Vulnerability management is integral to computer security and network security, and must not be confused with a Vulnerability assessment.\r\nVulnerability management is an ongoing process that includes proactive asset discovery, continuous monitoring, mitigation, remediation and defense tactics to protect your organization's modern IT attack surface from Cyber Exposure.\r\nVulnerabilities can be discovered with a vulnerability scanner, which analyzes a computer system in search of known vulnerabilities, such as open ports, insecure software configurations, and susceptibility to malware infections. They may also be identified by consulting public sources, such as NVD, or subscribing to a commercial vulnerability alerting services. Unknown vulnerabilities, such as a zero-day, may be found with fuzz testing, which can identify certain kinds of vulnerabilities, such as a buffer overflow with relevant test cases. Such analysis can be facilitated by test automation. In addition, antivirus software capable of heuristic analysis may discover undocumented malware if it finds software behaving suspiciously (such as attempting to overwrite a system file).\r\nCorrecting vulnerabilities may variously involve the installation of a patch, a change in network security policy, reconfiguration of software, or educating users about social engineering.\r\nNetwork vulnerabilities represent security gaps that could be abused by attackers to damage network assets, trigger a denial of service, and/or steal potentially sensitive information. Attackers are constantly looking for new vulnerabilities to exploit — and taking advantage of old vulnerabilities that may have gone unpatched.\r\nHaving a vulnerability management framework in place that regularly checks for new vulnerabilities is crucial for preventing cybersecurity breaches. Without a vulnerability testing and patch management system, old security gaps may be left on the network for extended periods of time. This gives attackers more of an opportunity to exploit vulnerabilities and carry out their attacks.\r\nOne statistic that highlights how crucial vulnerability management was featured in an Infosecurity Magazine article. According to survey data cited in the article, of the organizations that “suffered a breach, almost 60% were due to an unpatched vulnerability.” In other words, nearly 60% of the data breaches suffered by survey respondents could have been easily prevented simply by having a vulnerability management plan that would apply critical patches before attackers leveraged the vulnerability.","materialsDescription":" <span style=\"font-weight: bold;\">What is vulnerability management?</span>\r\nVulnerability management is a pro-active approach to managing network security by reducing the likelihood that flaws in code or design compromise the security of an endpoint or network.\r\n<span style=\"font-weight: bold;\">What processes does vulnerability management include?</span>\r\nVulnerability management processes include:\r\n<ul><li><span style=\"font-style: italic;\">Checking for vulnerabilities:</span> This process should include regular network scanning, firewall logging, penetration testing or use of an automated tool like a vulnerability scanner.</li><li><span style=\"font-style: italic;\">Identifying vulnerabilities:</span> This involves analyzing network scans and pen test results, firewall logs or vulnerability scan results to find anomalies that suggest a malware attack or other malicious event has taken advantage of a security vulnerability, or could possibly do so.</li><li><span style=\"font-style: italic;\">Verifying vulnerabilities:</span> This process includes ascertaining whether the identified vulnerabilities could actually be exploited on servers, applications, networks or other systems.

It provides a cost-effective alternative to SIEM (Security Information and Event Management).\r\nEveryday, the capabilities of attackers get more sophisticated and the volume of alerts becomes overwhelming and unmanageable. In-house teams might struggle to analyze and log data, which makes it harder than ever to determine if these threats are harmful. MDR can put a stop to attacks before they even happen. MDR technology monitors your systems and detects any unusual behavior, whilst our expert team responds to the threats detected within your business.\r\nMDR offers real-time threat intelligence, and is able to analyse behaviour which can be missed by traditional endpoint security technology. MDR also provides rapid identification of known threats, which in turn minimises overall attacks. Having remote incident investigation will minimise damage to your business, and will allow you to get back to work in no time. It’s important to note that using MDR services will allow third party access to your company's data. You need to consider working with a provider who understands and respects your data policy.","materialsDescription":" <span style=\"font-weight: bold;\">What is Managed Detection and Response?</span>\r\nManaged Detection and Response (MDR) is a managed cybersecurity service that provides intrusion detection of malware and malicious activity in your network, and assists in rapid incident response to eliminate those threats with succinct remediation actions. MDR typically combines a technology solution with outsourced security analysts that extend your technologies and team.\r\n<span style=\"font-weight: bold;\">Isn’t that What MSSPs or Managed SIEMs Do?</span>\r\nNo. Managed Security Service Providers (MSSPs) monitor network security controls and may send alerts when anomalies are identified. MSSPs typically do not investigate the anomalies to eliminate false positives, nor do they respond to real threats. This means that abnormalities in network usage are forwarded to your IT personnel who must then dig through the data to determine if there is a real threat and what to do about it.\r\n<span style=\"font-weight: bold;\">Doesn’t My Firewall Protect My Network?</span>\r\nFirewalls and other preventive forms of cybersecurity are very important and effective at preventing basic cyberattacks. However, over the past decade, it has become clear that preventive cybersecurity technologies are not enough to secure an organization’s network. Further, they are yet another source of alerts, log messages, and events that contribute to the “alert fatigue” being universally suffered today. Recent major hacks such as the Marriot Hack of 2018, the Anthem Hack of 2015, and the Target Hack of 2013 demonstrate how easily cybercriminals can breach networks at enterprise organizations to steal millions of credit card numbers, medical records, and other forms of PII/PHI.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Endpoint_Detection_and_Response.png"},{"id":481,"title":"WAF-web application firewall","alias":"waf-web-application-firewall","description":"A <span style=\"font-weight: bold; \">WAF (Web Application Firewall)</span> helps protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application. As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management?

Unfortunately, cybercrime happens every day, and great web security measures are needed to protect websites and web applications from becoming compromised.\r\nThat’s exactly what web security does – it is a system of protection measures and protocols that can protect your website or web application from being hacked or entered by unauthorized personnel. This integral division of Information Security is vital to the protection of websites, web applications, and web services. Anything that is applied over the Internet should have some form of web security to protect it.\r\nThere are a lot of factors that go into web security and web protection. Any website or application that is secure is surely backed by different types of checkpoints and techniques for keeping it safe.\r\nThere are a variety of security standards that must be followed at all times, and these standards are implemented and highlighted by the OWASP. Most experienced web developers from top cybersecurity companies will follow the standards of the OWASP as well as keep a close eye on the Web Hacking Incident Database to see when, how, and why different people are hacking different websites and services.\r\nEssential steps in protecting web apps from attacks include applying up-to-date encryption, setting proper authentication, continuously patching discovered vulnerabilities, avoiding data theft by having secure software development practices. The reality is that clever attackers may be competent enough to find flaws even in a fairly robust secured environment, and so a holistic security strategy is advised.\r\nThere are different types of technologies available for maintaining the best security standards. Some popular technical solutions for testing, building, and preventing threats include black and white box testing tools, fuzzing tools, WAF, security or vulnerability scanners, password cracking tools, and so on.","materialsDescription":" <span style=\"font-weight: bold; \">What is Malware?</span>\r\nThe name malware is short for ‘malicioussoftware’. Malware includes any software program that has been created to perform an unauthorised — and often harmful — action on a user’s device. Examples of malware include:\r\n<ul><li>Computer viruses</li><li>Word and Excel macro viruses</li><li>Boot sector viruses</li><li>Script viruses — including batch, Windows shell, Java and others</li><li>Keyloggers</li><li>Password stealers</li><li>Backdoor Trojan viruses</li><li>Other Trojan viruses</li><li>Crimeware</li><li>Spyware</li><li>Adware... and many other types of malicious software programs</li></ul>\r\n<span style=\"font-weight: bold; \">What is the difference between a computer virus and a worm?</span>\r\n<span style=\"font-weight: bold; \">Computer virus.</span> This is a type of malicious program that can replicate itself — so that it can spread from file to file on a computer, and can also spread from one computer to another. Computer viruses are often programmed to perform damaging actions — such as corrupting or deleting data. The longer a virus remains undetected on your machine, the greater the number of infected files that may be on your computer.\r\n<span style=\"font-weight: bold; \">Worms.</span> Worms are generally considered to be a subset of computer viruses — but with some specific differences:\r\n<ul><li>A worm is a computer program that replicates, but does not infect other files.</li><li>The worm will install itself once on a computer — and then look for a way to spread to other computers.</li><li>Whereas a virus is a set of code that adds itself to existing files, a worm exists as a separate, standalone file.</li></ul>\r\n<span style=\"font-weight: bold; \">What is a Trojan virus?</span>\r\nA Trojan is effectively a program that pretends to be legitimate software — but, when launched, it will perform a harmful action. Unlike computer viruses and worms, Trojans cannot spread by themselves. Typically, Trojans are installed secretly and they deliver their malicious payload without the user’s knowledge.\r\nCybercriminals use many different types of Trojans — and each has been designed to perform a specific malicious function. The most common are:\r\n<ul><li>Backdoor Trojans (these often include a keylogger)</li><li>Trojan Spies</li><li>Password stealing Trojans</li><li>Trojan Proxies — that convert your computer into a spam distribution machine</li></ul>\r\n<span style=\"font-weight: bold; \">Why are Trojan viruses called Trojans?</span>\r\nIn Greek mythology — during the Trojan war — the Greeks used subterfuge to enter the city of Troy. The Greeks constructed a massive wooden horse — and, unaware that the horse contained Greek soldiers, the Trojans pulled the horse into the city. At night, the Greek soldiers escaped from the horse and opened the city gates — for the Greek army to enter Troy.\r\nToday, Trojan viruses use subterfuge to enter unsuspecting users’ computers and devices.\r\n<span style=\"font-weight: bold; \">What is a Keylogger?</span>\r\nA keylogger is a program that can record what you type on your computer keyboard. Criminals use keyloggers to obtain confidential data — such as login details, passwords, credit card numbers, PINs and other items. Backdoor Trojans typically include an integrated keylogger.\r\n<span style=\"font-weight: bold; \">What is Phishing?</span>\r\nPhishing is a very specific type of cybercrime that is designed to trick you into disclosing valuable information — such as details about your bank account or credit cards. Often, cybercriminals will create a fake website that looks just like a legitimate site — such as a bank’s official website. The cybercriminal will try to trick you into visiting their fake site — typically by sending you an email that contains a hyperlink to the fake site. When you visit the fake website, it will generally ask you to type in confidential data — such as your login, password or PIN.\r\n<span style=\"font-weight: bold; \">What is Spyware?</span>\r\nSpyware is software that is designed to collect your data and send it to a third party — without your knowledge or consent. Spyware programs will often:\r\n<ul><li>Monitor the keys you press on your keyboard — using a keylogger</li><li>Collect confidential information — such as your passwords, credit card numbers, PIN numbers and more</li><li>Gather — or ‘harvest’ — email addresses from your computer</li><li>Track your Internet browsing habits</li></ul>\r\n<span style=\"font-weight: bold; \">What is a Rootkit?</span>\r\nRootkits are programs that hackers use in order to evade detection while trying to gain unauthorised access to a computer. Rootkits have been used increasingly as a form of stealth to hide Trojan virus activity. When installed on a computer, rootkits are invisible to the user and also take steps to avoid being detected by security software.\r\nThe fact that many people log into their computers with administrator rights — rather than creating a separate account with restricted access — makes it easier for cybercriminals to install a rootkit.\r\n<span style=\"font-weight: bold; \">What is a Botnet?</span>\r\nA botnet is a network of computers controlled by cybercriminals using a Trojan virus or other malicious program.\r\n<span style=\"font-weight: bold;\">What is a DDoS attack?</span>\r\nA Distributed-Denial-of-Service (DDoS) attack is similar to a DoS. However, a DDoS attack is conducted using multiple machines. Usually, for a DDoS attack, the hacker will use one security compromised computer as the ‘master’ machine that co-ordinates the attack by other ‘zombie machines’. Typically, the cybercriminal will compromise the security on the master and all of the zombie machines, by exploiting a vulnerability in an application on each computer — to install a Trojan or other piece of malicious code.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/security-web-application-security.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},"adnovum-nevisproxy":{"id":2195,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/nevisproxy.png","logo":true,"scheme":false,"title":"Adnovum nevisProxy","vendorVerified":0,"rating":"1.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"adnovum-nevisproxy","companyTitle":"Adnovum","companyTypes":["supplier","vendor"],"companyId":4569,"companyAlias":"adnovum","description":"<p>nevisProxy is a secure reverse proxy with integrated web application firewall (WAF).

The WAF addresses these code shortcomings by special configurations of rule sets, also known as policies.\r\nPreviously unknown vulnerabilities can be discovered through penetration testing or via a vulnerability scanner. A web application vulnerability scanner, also known as a web application security scanner, is defined in the SAMATE NIST 500-269 as “an automated program that examines web applications for potential security vulnerabilities. In addition to searching for web application-specific vulnerabilities, the tools also look for software coding errors.” Resolving vulnerabilities is commonly referred to as remediation. Corrections to the code can be made in the application but typically a more prompt response is necessary. In these situations, the application of a custom policy for a unique web application vulnerability to provide a temporary but immediate fix (known as a virtual patch) may be necessary.\r\nWAFs are not an ultimate security solution, rather they are meant to be used in conjunction with other network perimeter security solutions such as network firewalls and intrusion prevention systems to provide a holistic defense strategy.\r\nWAFs typically follow a positive security model, a negative security model, or a combination of both as mentioned by the SANS Institute. WAFs use a combination of rule-based logic, parsing, and signatures to detect and prevent attacks such as cross-site scripting and SQL injection. The OWASP produces a list of the top ten web application security flaws. All commercial WAF offerings cover these ten flaws at a minimum. There are non-commercial options as well. As mentioned earlier, the well-known open source WAF engine called ModSecurity is one of these options. A WAF engine alone is insufficient to provide adequate protection, therefore OWASP along with Trustwave's Spiderlabs help organize and maintain a Core-Rule Set via GitHub to use with the ModSecurity WAF engine.","materialsDescription":"A Web Application Firewall or WAF provides security for online services from malicious Internet traffic. WAFs detect and filter out threats such as the OWASP Top 10, which could degrade, compromise or bring down online applications.\r\n<span style=\"font-weight: bold;\">What are Web Application Firewalls?</span>\r\nWeb application firewalls assist load balancing by examining HTTP traffic before it reaches the application server. They also protect against web application vulnerability and unauthorized transfer of data from the web server at a time when security breaches are on the rise. According to the Verizon Data Breach Investigations Report, web application attacks were the most prevalent breaches in 2017 and 2018.\r\nThe PCI Security Standards Council defines a web application firewall as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\n<span style=\"font-weight: bold;\">How does a Web Application Firewall wWork?</span>\r\nA web application firewall (WAF) intercepts and inspects all HTTP requests using a security model based on a set of customized policies to weed out bogus traffic. WAFs block bad traffic outright or can challenge a visitor with a CAPTCHA test that humans can pass but a malicious bot or computer program cannot.\r\nWAFs follow rules or policies customized to specific vulnerabilities. As a result, this is how WAFs prevent DDoS attacks. Creating the rules on a traditional WAF can be complex and require expert administration. The Open Web Application Security Project maintains a list of the OWASP top web application security flaws for WAF policies to address.\r\nWAFs come in the form of hardware appliances, server-side software, or filter traffic as-a-service. WAFs can be considered as reverse proxies i.e. the opposite of a proxy server. Proxy servers protect devices from malicious applications, while WAFs protect web applications from malicious endpoints.\r\n<span style=\"font-weight: bold;\">What Are Some Web Application Firewall Benefits?</span>\r\nA web application firewall (WAF) prevents attacks that try to take advantage of the vulnerabilities in web-based applications. The vulnerabilities are common in legacy applications or applications with poor coding or designs. WAFs handle the code deficiencies with custom rules or policies.\r\nIntelligent WAFs provide real-time insights into application traffic, performance, security and threat landscape. This visibility gives administrators the flexibility to respond to the most sophisticated attacks on protected applications.\r\nWhen the Open Web Application Security Project identifies the OWASP top vulnerabilities, WAFs allow administrators to create custom security rules to combat the list of potential attack methods. An intelligent WAF analyzes the security rules matching a particular transaction and provides a real-time view as attack patterns evolve. Based on this intelligence, the WAF can reduce false positives.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between a Firewall and a Web Application Firewall?</span>\r\nA traditional firewall protects the flow of information between servers while a web application firewall is able to filter traffic for a specific web application. Network firewalls and web application firewalls are complementary and can work together.\r\nTraditional security methods include network firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS). They are effective at blocking bad L3-L4 traffic at the perimeter on the lower end (L3-L4) of the Open Systems Interconnection (OSI) model. Traditional firewalls cannot detect attacks in web applications because they do not understand Hypertext Transfer Protocol (HTTP) which occurs at layer 7 of the OSI model. They also only allow the port that sends and receives requested web pages from an HTTP server to be open or closed. This is why web application firewalls are effective for preventing attacks like SQL injections, session hijacking and Cross-Site Scripting (XSS).\r\n<span style=\"font-weight: bold;\">When Should You Use a Web Application Firewall?</span>\r\nAny business that uses a website to generate revenue should use a web application firewall to protect business data and services. Organizations that use online vendors should especially deploy web application firewalls because the security of outside groups cannot be controlled or trusted.\r\n<span style=\"font-weight: bold;\">How Do You Use a Web Application Firewall?</span>\r\nA web application firewall requires correct positioning, configuration, administration and monitoring. Web application firewall installation must include the following four steps: secure, monitor, test and improve. This should be a continuous process to ensure application specific protection.<br />The configuration of the firewall should be determined by the business rules and guardrails by the company’s security policy. This approach will allow the rules and filters in the web application firewall to define themselves.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAF_web_application_firewall_appliance.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},"airlock-web-application-firewall":{"id":1623,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/Airlock.png","logo":true,"scheme":false,"title":"Airlock Web Application Firewall","vendorVerified":0,"rating":"1.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"airlock-web-application-firewall","companyTitle":"Ergon Informatik AG","companyTypes":["supplier","vendor"],"companyId":4288,"companyAlias":"ergon-informatik-ag","description":"The Airlock Web Application Firewall offers a unique combination of protective mechanisms for web applications.

It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application. As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based.

This solution is less expensive than a network-based WAF and offers more customizability. The downside of a host-based WAF is the consumption of local server resources, implementation complexity, and maintenance costs. These components typically require engineering time, and may be costly.</li><li><span style=\"font-weight: bold; \">Cloud-based WAFs</span> offer an affordable option that is very easy to implement; they usually offer a turnkey installation that is as simple as a change in DNS to redirect traffic. Cloud-based WAFs also have a minimal upfront cost, as users pay monthly or annually for security as a service. Cloud-based WAFs can also offer a solution that is consistently updated to protect against the newest threats without any additional work or cost on the user’s end. The drawback of a cloud-based WAF is that users hand over the responsibility to a third-party, therefore some features of the WAF may be a black box to them. </li></ul>\r\n<p class=\"align-left\">&nbsp;</p>\r\n\r\n","materialsDescription":"<p class=\"align-center\"><span style=\"color: rgb(97, 97, 97); \"><span style=\"font-weight: bold; \">What types of attack WAF prevents?</span></span></p>\r\n<p class=\"align-left\"><span style=\"color: rgb(97, 97, 97); \">WAFs can prevent many attacks, including:</span></p>\r\n<ul><li><span style=\"color: rgb(97, 97, 97); \">Cross-site Scripting (XSS) — Attackers inject client-side scripts into web pages viewed by other users.</span></li><li><span style=\"color: rgb(97, 97, 97); \">SQL injection — Malicious code is inserted or injected into an web entry field that allows attackers to compromise the application and underlying systems.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Cookie poisoning — Modification of a cookie to gain unauthorized information about the user for purposes such as identity theft.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Unvalidated input — Attackers tamper with HTTP request (including the url, headers and form fields) to bypass the site’s security mechanisms.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Layer 7 DoS — An HTTP flood attack that utilizes valid requests in typical URL data retrievals.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Web scraping — Data scraping used for extracting data from websites.</span><span style=\"font-weight: bold; \"></span></li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What are some WAFs Benefits?</span></p>\r\nWeb app firewall prevents attacks that try to take advantage of the vulnerabilities in web-based applications.

AWS WAF gives you control over which traffic to allow or block to your web applications by defining customizable web security rules. You can use AWS WAF to create custom rules that block common attack patterns, such as SQL injection or cross-site scripting, and rules that are designed for your specific application. New rules can be deployed within minutes, letting you respond quickly to changing traffic patterns. Also, AWS WAF includes a full-featured API that you can use to automate the creation, deployment, and maintenance of web security rules.\r\n\r\n<span style=\"font-weight: bold;\">BENEFITS</span>\r\nINCREASED PROTECTION AGAINST WEB ATTACKS\r\nAWS WAF protects web applications from attacks by filtering traffic based on rules that you create. For example, you can filter web requests based on IP addresses, HTTP headers, HTTP body, or URI strings, which allows you to block common attack patterns, such as SQL injection or cross-site scripting.\r\nSECURITY INTEGRATED WITH HOW YOU DEVELOP APPLICATIONS\r\nEvery feature in AWS WAF can be configured using either the AWS WAF API or the AWS Management Console. This allows you to define application-specific rules that increase web security as you develop your application. This lets you put web security at multiple points in the development chain, from the hands of the developer initially writing code, to the DevOps engineer deploying software, to the security experts conducting an audit.\r\nEASE OF DEPLOYMENT &amp; MAINTENANCE\r\nAWS WAF is easy to deploy and protect application(s) deployed on either Amazon CloudFront as part of your CDN solution, the Application Load Balancer that fronts all your origin servers, or Amazon API Gateway for your APIs. There is no additional software to deploy except to enable AWS WAF on the right resource. You can centrally define your rules, and reuse them across all the web applications that you need to protect.\r\nIMPROVED WEB TRAFFIC VISIBILITY\r\nYou can set up AWS WAF to just monitor requests that match your filter criteria. AWS WAF gives near real-time visibility into your web traffic, which you can use to create new rules or alerts in Amazon CloudWatch.\r\nCOST EFFECTIVE WEB APPLICATION PROTECTION\r\nWith AWS WAF you pay only for what you use. AWS WAF provides a customizable, self-service offering, and pricing is based on how many rules you deploy and how many web requests your web application receives. There are no minimum fees and no upfront commitments.\r\nENHANCED SECURITY WITH MANAGED RULES\r\nWith Managed Rules for AWS WAF, you can quickly get started and protect your web application or APIs against common threats such as OWASP Top 10 security risks, threats specific to Content Management Systems (CMS), or emerging Common Vulnerabilities and Exposures (CVE). AWS security sellers will automatically update the managed rules for you as new exploits and bad actors emerge, so that you can spend more time building rather than managing security rules.<br /><br /><br />&nbsp;","shortDescription":"AWS WAF is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources.","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":true,"bonus":100,"usingCount":0,"sellingCount":0,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"AWS WAF - Web Application Firewall","keywords":"","description":"AWS WAF is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources.

It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application. As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based.

This solution is less expensive than a network-based WAF and offers more customizability. The downside of a host-based WAF is the consumption of local server resources, implementation complexity, and maintenance costs. These components typically require engineering time, and may be costly.</li><li><span style=\"font-weight: bold; \">Cloud-based WAFs</span> offer an affordable option that is very easy to implement; they usually offer a turnkey installation that is as simple as a change in DNS to redirect traffic.

They both do away with the need for on-premises network security appliances, yet still provide centralized control and ease of use for building network security defense in depth. While UTM systems and <span style=\"font-weight: bold; \">next-generation firewalls (NGFWs)</span> are sometimes comparable, unified threat management device includes added security features that NGFWs don't offer.\r\nOriginally developed to fill the network security gaps left by traditional firewalls, NGFWs usually include application intelligence and intrusion prevention systems, as well as denial-of-service protection. Unified threat management devices offer multiple layers of network security, including next-generation firewalls, intrusion detection/prevention systems, antivirus, virtual private networks (VPN), spam filtering and URL filtering for web content.\r\nUnified threat management appliance has gained traction in the industry due to the emergence of blended threats, which are combinations of different types of malware and attacks that target separate parts of the network simultaneously. By creating a single point of defense and providing a single console, unified security management make dealing with varied threats much easier.\r\nUnified threat management products provide increased protection and visibility, as well as control over network security, reducing complexity. Unified threat management system typically does this via inspection methods that address different types of threats. These methods include:\r\n<ul><li><span style=\"font-weight: bold; \">Flow-based inspection,</span> also known as stream-based inspection, samples data that enters a UTM device, and then uses pattern matching to determine whether there is malicious content in the data flow.</li><li> <span style=\"font-weight: bold; \">Proxy-based inspection</span> acts as a proxy to reconstruct the content entering a UTM device, and then executes a full inspection of the content to search for potential security threats. If the content is clean, the device sends the content to the user. However, if a virus or other security threat is detected, the device removes the questionable content, and then sends the file or webpage to the user.</li></ul>\r\n\r\n","materialsDescription":"<h1 class=\"align-center\"> How UTM is deployed?</h1>\r\nBusinesses can implement UTM as a UTM appliance that connects to a company's network, as a software program running on an existing network server, or as a service that works in a cloud environment.\r\nUTMs are particularly useful in organizations that have many branches or retail outlets that have traditionally used dedicated WAN, but are increasingly using public internet connections to the headquarters/data center. Using a UTM in these cases gives the business more insight and better control over the security of those branch or retail outlets.\r\nBusinesses can choose from one or more methods to deploy UTM to the appropriate platforms, but they may also find it most suitable to select a combination of platforms. Some of the options include installing unified threat management software on the company's servers in a data center; using software-based UTM products on cloud-based servers; using traditional UTM hardware appliances that come with preintegrated hardware and software; or using virtual appliances, which are integrated software suites that can be deployed in virtual environments.\r\n<h1 class=\"align-center\">Benefits of Using a Unified Threat Management Solution</h1>\r\nUTM solutions offer unique benefits to small and medium businesses that are looking to enhance their security programs. Because the capabilities of multiple specialized programs are contained in a single appliance, UTM threat management reduces the complexity of a company’s security system. Similarly, having one program that controls security reduces the amount of training that employees receive when being hired or migrating to a new system and allows for easy management in the future. This can also save money in the long run as opposed to having to buy multiple devices.\r\nSome UTM solutions provide additional benefits for companies in strictly regulated industries. Appliances that use identity-based security to report on user activity while enabling policy creation based on user identity meet the requirements of regulatory compliance such as HIPPA, CIPA, and GLBA that require access controls and auditing that meet control data leakage.\r\nUTM solutions also help to protect networks against combined threats. These threats consist of different types of malware and attacks that target separate parts of the network simultaneously. When using separate appliances for each security wall, preventing these combined attacks can be difficult. This is because each security wall has to be managed individually in order to remain up-to-date with the changing security threats. Because it is a single point of defense, UTM’s make dealing with combined threats easier.\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_UTM.jpg"},{"id":481,"title":"WAF-web application firewall","alias":"waf-web-application-firewall","description":"A <span style=\"font-weight: bold; \">WAF (Web Application Firewall)</span> helps protect web applications by filtering and monitoring HTTP traffic between a web application and the Internet.

It is deployed in front of web applications and analyzes bi-directional web-based (HTTP) traffic - detecting and blocking anything malicious. The OWASP provides a broad technical definition for a WAF as “a security solution on the web application level which - from a technical point of view - does not depend on the application itself.” According to the PCI DSS Information Supplement for requirement 6.6, a WAF is defined as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.” In other words, a WAF can be a physical appliance that prevents vulnerabilities in web applications from being exploited by outside threats. These vulnerabilities may be because the application itself is a legacy type or it was insufficiently coded by design. The WAF addresses these code shortcomings by special configurations of rule sets, also known as policies.\r\nPreviously unknown vulnerabilities can be discovered through penetration testing or via a vulnerability scanner. A web application vulnerability scanner, also known as a web application security scanner, is defined in the SAMATE NIST 500-269 as “an automated program that examines web applications for potential security vulnerabilities. In addition to searching for web application-specific vulnerabilities, the tools also look for software coding errors.” Resolving vulnerabilities is commonly referred to as remediation. Corrections to the code can be made in the application but typically a more prompt response is necessary. In these situations, the application of a custom policy for a unique web application vulnerability to provide a temporary but immediate fix (known as a virtual patch) may be necessary.\r\nWAFs are not an ultimate security solution, rather they are meant to be used in conjunction with other network perimeter security solutions such as network firewalls and intrusion prevention systems to provide a holistic defense strategy.\r\nWAFs typically follow a positive security model, a negative security model, or a combination of both as mentioned by the SANS Institute. WAFs use a combination of rule-based logic, parsing, and signatures to detect and prevent attacks such as cross-site scripting and SQL injection. The OWASP produces a list of the top ten web application security flaws. All commercial WAF offerings cover these ten flaws at a minimum. There are non-commercial options as well. As mentioned earlier, the well-known open source WAF engine called ModSecurity is one of these options. A WAF engine alone is insufficient to provide adequate protection, therefore OWASP along with Trustwave's Spiderlabs help organize and maintain a Core-Rule Set via GitHub to use with the ModSecurity WAF engine.","materialsDescription":"A Web Application Firewall or WAF provides security for online services from malicious Internet traffic.

WAFs block bad traffic outright or can challenge a visitor with a CAPTCHA test that humans can pass but a malicious bot or computer program cannot.\r\nWAFs follow rules or policies customized to specific vulnerabilities. As a result, this is how WAFs prevent DDoS attacks. Creating the rules on a traditional WAF can be complex and require expert administration. The Open Web Application Security Project maintains a list of the OWASP top web application security flaws for WAF policies to address.\r\nWAFs come in the form of hardware appliances, server-side software, or filter traffic as-a-service. WAFs can be considered as reverse proxies i.e. the opposite of a proxy server.

Security software is a broad term that encompasses a suite of different types of software that deliver data and computer and network security in various forms. \r\nSecurity software can protect a computer from viruses, malware, unauthorized users and other security exploits originating from the Internet. Different types of security software include anti-virus software, firewall software, network security software, Internet security software, malware/spamware removal and protection software, cryptographic software, and more.\r\nIn end-user computing environments, anti-spam and anti-virus security software is the most common type of software used, whereas enterprise users add a firewall and intrusion detection system on top of it. \r\nSecurity soft may be focused on preventing attacks from reaching their target, on limiting the damage attacks can cause if they reach their target and on tracking the damage that has been caused so that it can be repaired. As the nature of malicious code evolves, security software also evolves.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">Firewall. </span>Firewall security software prevents unauthorized users from accessing a computer or network without restricting those who are authorized. Firewalls can be implemented with hardware or software. Some computer operating systems include software firewalls in the operating system itself. For example, Microsoft Windows has a built-in firewall. Routers and servers can include firewalls. There are also dedicated hardware firewalls that have no other function other than protecting a network from unauthorized access.\r\n<span style=\"font-weight: bold; \">Antivirus.</span> Antivirus solutions work to prevent malicious code from attacking a computer by recognizing the attack before it begins. But it is also designed to stop an attack in progress that could not be prevented, and to repair damage done by the attack once the attack abates. Antivirus software is useful because it addresses security issues in cases where attacks have made it past a firewall. New computer viruses appear daily, so antivirus and security software must be continuously updated to remain effective.\r\n<span style=\"font-weight: bold; \">Antispyware.</span> While antivirus software is designed to prevent malicious software from attacking, the goal of antispyware software is to prevent unauthorized software from stealing information that is on a computer or being processed through the computer. Since spyware does not need to attempt to damage data files or the operating system, it does not trigger antivirus software into action. However, antispyware software can recognize the particular actions spyware is taking by monitoring the communications between a computer and external message recipients. When communications occur that the user has not authorized, antispyware can notify the user and block further communications.\r\n<span style=\"font-weight: bold; \">Home Computers.</span> Home computers and some small businesses usually implement&nbsp; security software at the desktop level - meaning on the PC itself. This category of computer security and protection, sometimes referred to as end-point security, remains resident, or continuously operating, on the desktop. Because the software is running, it uses system resources, and can slow the computer's performance. However, because it operates in real time, it can react rapidly to attacks and seek to shut them down when they occur.\r\n<span style=\"font-weight: bold; \">Network Security.</span> When several computers are all on the same network, it's more cost-effective to implement security at the network level. Antivirus software can be installed on a server and then loaded automatically to each desktop. However firewalls are usually installed on a server or purchased as an independent device that is inserted into the network where the Internet connection comes in. All of the computers inside the network communicate unimpeded, but any data going in or out of the network over the Internet is filtered trough the firewall.<br /><br /><br />","materialsDescription":"<h1 class=\"align-center\"> <span style=\"font-weight: normal; \">What is IT security software?</span></h1>\r\nIT security software provides protection to businesses’ computer or network.

It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application.

As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based.

Based on this intelligence, the WAF can reduce false positives.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between a Firewall and a Web Application Firewall?</span>\r\nA traditional firewall protects the flow of information between servers while a web application firewall is able to filter traffic for a specific web application. Network firewalls and web application firewalls are complementary and can work together.\r\nTraditional security methods include network firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS). They are effective at blocking bad L3-L4 traffic at the perimeter on the lower end (L3-L4) of the Open Systems Interconnection (OSI) model. Traditional firewalls cannot detect attacks in web applications because they do not understand Hypertext Transfer Protocol (HTTP) which occurs at layer 7 of the OSI model. They also only allow the port that sends and receives requested web pages from an HTTP server to be open or closed. This is why web application firewalls are effective for preventing attacks like SQL injections, session hijacking and Cross-Site Scripting (XSS).\r\n<span style=\"font-weight: bold;\">When Should You Use a Web Application Firewall?</span>\r\nAny business that uses a website to generate revenue should use a web application firewall to protect business data and services. Organizations that use online vendors should especially deploy web application firewalls because the security of outside groups cannot be controlled or trusted.\r\n<span style=\"font-weight: bold;\">How Do You Use a Web Application Firewall?</span>\r\nA web application firewall requires correct positioning, configuration, administration and monitoring. Web application firewall installation must include the following four steps: secure, monitor, test and improve. This should be a continuous process to ensure application specific protection.<br />The configuration of the firewall should be determined by the business rules and guardrails by the company’s security policy. This approach will allow the rules and filters in the web application firewall to define themselves.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAF_web_application_firewall_appliance.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},"core-security":{"id":4366,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/ServerChoice.png","logo":true,"scheme":false,"title":"CORE Security","vendorVerified":0,"rating":"0.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"core-security","companyTitle":"ServerChoice","companyTypes":["supplier","vendor"],"companyId":6756,"companyAlias":"serverchoice","description":"<p class=\"align-center\"><span style=\"font-weight: bold;\">Introducing CORE Security</span></p>\r\nWhen it comes to securing your cloud, you need to peace of mind that security’s at the core of your hosted infrastructure.

By focusing on the location, classification and monitoring of information at rest, in use and in motion, this solution can go far in helping an enterprise get a handle on what information it has, and in stopping the numerous leaks of information that occur each day. DLP is not a plug-and-play solution. The successful implementation of this technology requires significant preparation and diligent ongoing maintenance. Enterprises seeking to integrate and implement DLP should be prepared for a significant effort that, if done correctly, can greatly reduce risk to the organization.

Unfortunately, not always the management of companies is able to do this if it comes to information security threats. The key to successfully protecting against information leaks and other threats lies in the skillful use of both organizational and technical means of monitoring personnel actions.\r\n<span style=\"font-weight: bold;\">How should the personnel management system in the company be organized to minimize the risks of leakage of confidential information?</span>\r\nA company must have a special employee responsible for information security, and a large department must have a department directly reporting to the head of the company.\r\n<span style=\"font-weight: bold;\">Which industry representatives are most likely to encounter confidential information leaks?</span>\r\nMore than others, representatives of such industries as industry, energy, and retail trade suffer from leaks. Other industries traditionally exposed to leakage risks — banking, insurance, IT — are usually better at protecting themselves from information risks, and for this reason they are less likely to fall into similar situations.\r\n<span style=\"font-weight: bold;\">What should be adequate measures to protect against leakage of information for an average company?</span>\r\nFor each organization, the question of protection measures should be worked out depending on the specifics of its work, but developing information security policies, instructing employees, delineating access to confidential data and implementing a DLP system are necessary conditions for successful leak protection for any organization. Among all the technical means to prevent information leaks, the DLP system is the most effective today, although its choice must be taken very carefully to get the desired result. So, it should control all possible channels of data leakage, support automatic detection of confidential information in outgoing traffic, maintain control of work laptops that temporarily find themselves outside the corporate network...\r\n<span style=\"font-weight: bold;\">Is it possible to give protection against information leaks to outsourcing?</span>\r\nFor a small company, this may make sense because it reduces costs. However, it is necessary to carefully select the service provider, preferably before receiving recommendations from its current customers.\r\n<span style=\"font-weight: bold;\">What data channels need to be monitored to prevent leakage of confidential information?</span>\r\nAll channels used by employees of the organization - e-mail, Skype, HTTP World Wide Web protocol ... It is also necessary to monitor the information recorded on external storage media and sent to print, plus periodically check the workstation or laptop of the user for files that are there saying should not.\r\n<span style=\"font-weight: bold;\">What to do when the leak has already happened?</span>\r\nFirst of all, you need to notify those who might suffer - silence will cost your reputation much more. Secondly, you need to find the source and prevent further leakage. Next, you need to assess where the information could go, and try to somehow agree that it does not spread further. In general, of course, it is easier to prevent the leakage of confidential information than to disentangle its consequences.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Data_Leak_Prevention.png"},{"id":34,"title":"ITSM - IT Service Management","alias":"itsm-it-service-management","description":"<span style=\"font-weight: bold; \">IT service management (ITSM)</span> is the process of designing, delivering, managing, and improving the IT services an organization provides to its end users. ITSM is focused on aligning IT processes and services with business objectives to help an organization grow.\r\nITSM positions IT services as the key means of delivering and obtaining value, where an internal or external IT service provider works with business customers, at the same time taking responsibility for the associated costs and risks. ITSM works across the whole lifecycle of a service, from the original strategy, through design, transition and into live operation.\r\nTo ensure sustainable quality of IT services, ITSM establishes a set of practices, or processes, constituting a service management system. There are industrial, national and international standards for IT service management solutions, setting up requirements and good practices for the management system. \r\nITSM system is based on a set of principles, such as focusing on value and continual improvement. It is not just a set of processes – it is a cultural mindset to ensure that the desired outcome for the business is achieved. \r\n<span style=\"font-weight: bold; \">ITIL (IT Infrastructure Library)</span> is a framework of best practices and recommendations for managing an organization's IT operations and services. IT service management processes, when built based on the ITIL framework, pave the way for better IT service operations management and improved business. To summarize, ITIL is a set of guidelines for effective IT service management best practices. ITIL has evolved beyond the delivery of services to providing end-to-end value delivery. The focus is now on the co-creation of value through service relationships. \r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">ITSM processes typically include five stages, all based on the ITIL framework:</span></p>\r\n<span style=\"font-weight: bold; \">ITSM strategy.</span> This stage forms the foundation or the framework of an organization's ITSM process building. It involves defining the services that the organization will offer, strategically planning processes, and recognizing and developing the required assets to keep processes moving. \r\n<span style=\"font-weight: bold; \">Service design.</span> This stage's main aim is planning and designing the IT services the organization offers to meet business demands. It involves creating and designing new services as well as assessing current services and making relevant improvements.\r\n<span style=\"font-weight: bold; \">Service transition.</span> Once the designs for IT services and their processes have been finalized, it's important to build them and test them out to ensure that processes flow. IT teams need to ensure that the designs don't disrupt services in any way, especially when existing IT service processes are upgraded or redesigned. This calls for change management, evaluation, and risk management. \r\n<span style=\"font-weight: bold; \">Service operation. </span>This phase involves implementing the tried and tested new or modified designs in a live environment. While in this stage, the processes have already been tested and the issues fixed, but new processes are bound to have hiccups—especially when customers start using the services. \r\n<span style=\"font-weight: bold;\">Continual service improvement (CSI).</span> Implementing IT processes successfully shouldn't be the final stage in any organization. There's always room for improvement and new development based on issues that pop up, customer needs and demands, and user feedback.\r\n\r\n","materialsDescription":"<h1 class=\"align-center\">Benefits of efficient ITSM processes</h1>\r\nIrrespective of the size of business, every organization is involved in IT service management in some way. ITSM ensures that incidents, service requests, problems, changes, and IT assets—in addition to other aspects of IT services—are managed in a streamlined way.\r\nIT teams in your organization can employ various workflows and best practices in ITSM, as outlined in ITIL. Effective IT service management can have positive effects on an IT organization's overall function.\r\nHere are the 10 key benefits of ITSM:\r\n<ul><li>&nbsp;&nbsp;&nbsp; Lower costs for IT operations</li><li>&nbsp;&nbsp;&nbsp; Higher returns on IT investments</li><li>&nbsp;&nbsp;&nbsp; Minimal service outages</li><li>&nbsp;&nbsp;&nbsp; Ability to establish well-defined, repeatable, and manageable IT processes</li><li>&nbsp;&nbsp;&nbsp; Efficient analysis of IT problems to reduce repeat incidents</li><li>&nbsp;&nbsp;&nbsp; Improved efficiency of IT help desk teams</li><li>&nbsp;&nbsp;&nbsp; Well-defined roles and responsibilities</li><li>&nbsp;&nbsp;&nbsp; Clear expectations on service levels and service availability</li><li>&nbsp;&nbsp;&nbsp; Risk-free implementation of IT changes</li><li>&nbsp;&nbsp;&nbsp; Better transparency into IT processes and services</li></ul>\r\n<h1 class=\"align-center\">How to choose an ITSM tool?</h1>\r\nWith a competent IT service management goal in mind, it's important to invest in a service desk solution that caters to your business needs. It goes without saying, with more than 150 service desk tools to choose from, selecting the right one is easier said than done. Here are a few things to keep in mind when choosing an ITSM products:\r\n<span style=\"font-weight: bold; \">Identify key processes and their dependencies. </span>Based on business goals, decide which key ITSM processes need to be implemented and chart out the integrations that need to be established to achieve those goals. \r\n<span style=\"font-weight: bold; \">Consult with ITSM experts.</span> Participate in business expos, webinars, demos, etc., and educate yourself about the various options that are available in the market. Reports from expert analysts such as Gartner and Forrester are particularly useful as they include reviews of almost every solution, ranked based on multiple criteria.\r\n<span style=\"font-weight: bold; \">Choose a deployment option.</span> Every business has a different IT infrastructure model. Selecting an on-premises or software as a service (SaaS IT service management) tool depends on whether your business prefers to host its applications and data on its own servers or use a public or private cloud.\r\n<span style=\"font-weight: bold; \">Plan ahead for the future.</span> Although it's important to consider the &quot;needs&quot; primarily, you shouldn't rule out the secondary or luxury capabilities. If the ITSM tool doesn't have the potential to adapt to your needs as your organization grows, it can pull you back from progressing. Draw a clear picture of where your business is headed and choose an service ITSM that is flexible and technology-driven.\r\n<span style=\"font-weight: bold;\">Don't stop with the capabilities of the ITSM tool.</span> It might be tempting to assess an ITSM tool based on its capabilities and features but it's important to evaluate the vendor of the tool. A good IT support team, and a vendor that is endorsed for their customer-vendor relationship can take your IT services far. Check Gartner's magic quadrant and other analyst reports, along with product and support reviews to ensure that the said tool provides good customer support.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_ITSM.png"},{"id":41,"title":"Antispam","alias":"antispam","description":"In each system, which involves the communication of users, there is always the problem of spam, or the mass mailing of unsolicited emails, which is solved using the antispam system.

There are many programs that help to cope with this task, but not all of them are equally useful. The main objective of such programs is to stop sending unsolicited letters, however, the methods of assessing and suppressing such actions can be not only beneficial but also detrimental to your organization.

At the most basic level, a SIEM system can be rules-based or employ a statistical correlation engine to establish relationships between event log entries. Advanced SIEM products have evolved to include user and entity behavior analytics (UEBA) and security orchestration and automated response (SOAR). \r\nThe acronyms SEM, SIM and SIEM have sometimes been used interchangeably, but generally refer to the different primary focus of products:\r\n<ul><li><span style=\"font-weight: bold;\">Log management:</span> Focus on simple collection and storage of log messages and audit trails.</li><li><span style=\"font-weight: bold;\">Security information management (SIM):</span> Long-term storage as well as analysis and reporting of log data.</li><li><span style=\"font-weight: bold;\">Security event manager (SEM):</span> Real-time monitoring, correlation of events, notifications and console views.</li><li><span style=\"font-weight: bold;\">Security information event management (SIEM):</span> Combines SIM and SEM and provides real-time analysis of security alerts generated by network hardware and applications.</li><li><span style=\"font-weight: bold;\">Managed Security Service (MSS) or Managed Security Service Provider (MSSP):</span> The most common managed services appear to evolve around connectivity and bandwidth, network monitoring, security, virtualization, and disaster recovery.</li><li><span style=\"font-weight: bold;\">Security as a service (SECaaS):</span> These security services often include authentication, anti-virus, anti-malware/spyware, intrusion detection, Penetration testing and security event management, among others.</li></ul>\r\nToday, most of SIEM technology works by deploying multiple collection agents in a hierarchical manner to gather security-related events from end-user devices, servers, network equipment, as well as specialized security equipment like firewalls, antivirus or intrusion prevention systems. The collectors forward events to a centralized management console where security analysts sift through the noise, connecting the dots and prioritizing security incidents.\r\nSome of the most important features to review when evaluating Security Information and Event Management software are:\r\n<ol><li><span style=\"font-weight: bold; \">Integration with other controls:</span> Can the system give commands to other enterprise security controls to prevent or stop attacks in progress?</li><li><span style=\"font-weight: bold; \">Artificial intelligence:</span> Can the system improve its own accuracy by through machine and deep learning?</li><li><span style=\"font-weight: bold; \">Threat intelligence feeds:</span>&nbsp; Can the system support threat intelligence feeds of the organization's choosing or is it mandated to use a particular feed?</li><li><span style=\"font-weight: bold; \">Robust compliance reporting:</span>&nbsp; Does the system include built-in reports for common compliance needs and the provide the organization with the ability to customize or create new compliance reports?</li><li><span style=\"font-weight: bold; \">Forensics capabilities:</span>&nbsp; Can the system capture additional information about security events by recording the headers and contents of packets of interest? </li></ol>\r\n\r\n\r\n","materialsDescription":"<h1 class=\"align-center\"> Why is SIEM Important?</h1>\r\nSIEM has become a core security component of modern organizations. The main reason is that every user or tracker leaves behind a virtual trail in a network’s log data. SIEM software is designed to use this log data in order to generate insight into past attacks and events. A SIEM solution not only identifies that an attack has happened, but allows you to see how and why it happened as well.\r\nAs organizations update and upscale to increasingly complex IT infrastructures, SIEM has become even more important in recent years. Contrary to popular belief, firewalls and antivirus packages are not enough to protect a network in its entirety. Zero-day attacks can still penetrate a system’s defenses even with these security measures in place.\r\nSIEM addresses this problem by detecting attack activity and assessing it against past behavior on the network. A security event monitoring has the ability to distinguish between legitimate use and a malicious attack. This helps to increase a system’s incident protection and avoid damage to systems and virtual property.\r\nThe use of SIEM also helps companies to comply with a variety of industry cyber management regulations. Log management is the industry standard method of auditing activity on an IT network. SIEM management provides the best way to meet this regulatory requirement and provide transparency over logs in order to generate clear insights and improvements.\r\n<h1 class=\"align-center\">Evaluation criteria for security information and event management software:</h1>\r\n<ul><li>Threat identification: Raw log form vs. descriptive.</li><li>Threat tracking: Ability to track through the various events, from source to destination.</li><li>Policy enforcement: Ability to enforce defined polices.</li><li>Application analysis: Ability to analyze application at Layer 7 if necessary.</li><li>Business relevance of events: Ability to assign business risk to events and have weighted threat levels.</li><li>Measuring changes and improvements: Ability to track configuration changes to devices.</li><li>Asset-based information: Ability to gather information on devices on the network.</li><li>Anomalous behavior (server): Ability to trend and see changes in how it communicates to others.</li><li>Anomalous behavior (network): Ability to trend and see how communications pass throughout the network.</li><li>Anomalous behavior (application): Ability to trend and see changes in how it communicates to others.</li><li>User monitoring: User activity, logging in, applications usage, etc.</li></ul>\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_SIEM.png"},{"id":52,"title":"SaaS - software as a service","alias":"saas-software-as-a-service","description":"<span style=\"font-weight: bold;\">Software as a service (SaaS)</span> is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted. It is sometimes referred to as &quot;on-demand software&quot;, and was formerly referred to as &quot;software plus services&quot; by Microsoft.\r\n SaaS services is typically accessed by users using a thin client, e.g. via a web browser. SaaS software solutions has become a common delivery model for many business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD software, development software, gamification, virtualization, accounting, collaboration, customer relationship management (CRM), Management Information Systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), talent acquisition, learning management systems, content management (CM), Geographic Information Systems (GIS), and service desk management. SaaS has been incorporated into the strategy of nearly all leading enterprise software companies.\r\nSaaS applications are also known as <span style=\"font-weight: bold;\">Web-based software</span>, <span style=\"font-weight: bold;\">on-demand software</span> and<span style=\"font-weight: bold;\"> hosted software</span>.\r\nThe term &quot;Software as a Service&quot; (SaaS) is considered to be part of the nomenclature of cloud computing, along with Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Desktop as a Service (DaaS),managed software as a service (MSaaS), mobile backend as a service (MBaaS), and information technology management as a service (ITMaaS).\r\nBecause SaaS is based on cloud computing it saves organizations from installing and running applications on their own systems. That eliminates or at least reduces the associated costs of hardware purchases and maintenance and of software and support. The initial setup cost for a SaaS application is also generally lower than it for equivalent enterprise software purchased via a site license.\r\nSometimes, the use of SaaS cloud software can also reduce the long-term costs of software licensing, though that depends on the pricing model for the individual SaaS offering and the enterprise’s usage patterns. In fact, it’s possible for SaaS to cost more than traditional software licenses. This is an area IT organizations should explore carefully.<br />SaaS also provides enterprises the flexibility inherent with cloud services: they can subscribe to a SaaS offering as needed rather than having to buy software licenses and install the software on a variety of computers. The savings can be substantial in the case of applications that require new hardware purchases to support the software.<br /><br /><br /><br />","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Who uses SaaS?</span></h1>\r\nIndustry analyst Forrester Research notes that SaaS adoption has so far been concentrated mostly in human resource management (HRM), customer relationship management (CRM), collaboration software (e.g., email), and procurement solutions, but is poised to widen. Today it’s possible to have a data warehouse in the cloud that you can access with business intelligence software running as a service and connect to your cloud-based ERP like NetSuite or Microsoft Dynamics.The dollar savings can run into the millions. And SaaS installations are often installed and working in a fraction of the time of on-premises deployments—some can be ready in hours. \r\nSales and marketing people are likely familiar with Salesforce.com, the leading SaaS CRM software, with millions of users across more than 100,000 customers. Sales is going SaaS too, with apps available to support sales in order management, compensation, quote production and configure, price, quoting, electronic signatures, contract management and more.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">Why SaaS? Benefits of software as a service</span></h1>\r\n<ul><li><span style=\"font-weight: bold;\">Lower cost of entry</span>. With SaaS solution, you pay for what you need, without having to buy hardware to host your new applications. Instead of provisioning internal resources to install the software, the vendor provides APIs and performs much of the work to get their software working for you. The time to a working solution can drop from months in the traditional model to weeks, days or hours with the SaaS model. In some businesses, IT wants nothing to do with installing and running a sales app. In the case of funding software and its implementation, this can be a make-or-break issue for the sales and marketing budget, so the lower cost really makes the difference.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Reduced time to benefit/rapid prototyping</span>. In the SaaS model, the software application is already installed and configured. Users can provision the server for the cloud and quickly have the application ready for use. This cuts the time to benefit and allows for rapid demonstrations and prototyping. With many SaaS companies offering free trials, this means a painless proof of concept and discovery phase to prove the benefit to the organization. </li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Pay as you go</span>. SaaS business software gives you the benefit of predictable costs both for the subscription and to some extent, the administration. Even as you scale, you can have a clear idea of what your costs will be. This allows for much more accurate budgeting, especially as compared to the costs of internal IT to manage upgrades and address issues for an owned instance.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">The SaaS vendor is responsible for upgrades, uptime and security</span>. Under the SaaS model, since the software is hosted by the vendor, they take on the responsibility for maintaining the software and upgrading it, ensuring that it is reliable and meeting agreed-upon service level agreements, and keeping the application and its data secure.&nbsp; While some IT people worry about Software as a Service security outside of the enterprise walls, the likely truth is that the vendor has a much higher level of security than the enterprise itself would provide. Many will have redundant instances in very secure data centers in multiple geographies.&nbsp; Also, the data is being automatically backed up by the vendor, providing additional security and peace of mind.

Vulnerability management is integral to computer security and network security, and must not be confused with a Vulnerability assessment.\r\nVulnerability management is an ongoing process that includes proactive asset discovery, continuous monitoring, mitigation, remediation and defense tactics to protect your organization's modern IT attack surface from Cyber Exposure.\r\nVulnerabilities can be discovered with a vulnerability scanner, which analyzes a computer system in search of known vulnerabilities, such as open ports, insecure software configurations, and susceptibility to malware infections. They may also be identified by consulting public sources, such as NVD, or subscribing to a commercial vulnerability alerting services. Unknown vulnerabilities, such as a zero-day, may be found with fuzz testing, which can identify certain kinds of vulnerabilities, such as a buffer overflow with relevant test cases. Such analysis can be facilitated by test automation. In addition, antivirus software capable of heuristic analysis may discover undocumented malware if it finds software behaving suspiciously (such as attempting to overwrite a system file).\r\nCorrecting vulnerabilities may variously involve the installation of a patch, a change in network security policy, reconfiguration of software, or educating users about social engineering.\r\nNetwork vulnerabilities represent security gaps that could be abused by attackers to damage network assets, trigger a denial of service, and/or steal potentially sensitive information. Attackers are constantly looking for new vulnerabilities to exploit — and taking advantage of old vulnerabilities that may have gone unpatched.\r\nHaving a vulnerability management framework in place that regularly checks for new vulnerabilities is crucial for preventing cybersecurity breaches. Without a vulnerability testing and patch management system, old security gaps may be left on the network for extended periods of time. This gives attackers more of an opportunity to exploit vulnerabilities and carry out their attacks.\r\nOne statistic that highlights how crucial vulnerability management was featured in an Infosecurity Magazine article. According to survey data cited in the article, of the organizations that “suffered a breach, almost 60% were due to an unpatched vulnerability.” In other words, nearly 60% of the data breaches suffered by survey respondents could have been easily prevented simply by having a vulnerability management plan that would apply critical patches before attackers leveraged the vulnerability.","materialsDescription":" <span style=\"font-weight: bold;\">What is vulnerability management?</span>\r\nVulnerability management is a pro-active approach to managing network security by reducing the likelihood that flaws in code or design compromise the security of an endpoint or network.\r\n<span style=\"font-weight: bold;\">What processes does vulnerability management include?</span>\r\nVulnerability management processes include:\r\n<ul><li><span style=\"font-style: italic;\">Checking for vulnerabilities:</span> This process should include regular network scanning, firewall logging, penetration testing or use of an automated tool like a vulnerability scanner.</li><li><span style=\"font-style: italic;\">Identifying vulnerabilities:</span> This involves analyzing network scans and pen test results, firewall logs or vulnerability scan results to find anomalies that suggest a malware attack or other malicious event has taken advantage of a security vulnerability, or could possibly do so.</li><li><span style=\"font-style: italic;\">Verifying vulnerabilities:</span> This process includes ascertaining whether the identified vulnerabilities could actually be exploited on servers, applications, networks or other systems.

Unlike other areas of digital forensics, network investigations deal with volatile and dynamic information. Network traffic is transmitted and then lost, so network forensics is often a pro-active investigation.\r\nNetwork forensics generally has two uses. The first, relating to security, involves monitoring a network for anomalous traffic and identifying intrusions. An attacker might be able to erase all log files on a compromised host; network-based evidence might therefore be the only evidence available for forensic analysis. The second form relates to law enforcement. In this case analysis of captured network traffic can include tasks such as reassembling transferred files, searching for keywords and parsing human communication such as emails or chat sessions.\r\nTwo systems are commonly used to collect network data; a brute force &quot;catch it as you can&quot; and a more intelligent &quot;stop look listen&quot; method.\r\nNetwork forensics is a comparatively new field of forensic science. The growing popularity of the Internet in homes means that computing has become network-centric and data is now available outside of disk-based digital evidence. Network forensics can be performed as a standalone investigation or alongside a computer forensics analysis (where it is often used to reveal links between digital devices or reconstruct how a crime was committed).\r\nMarcus Ranum is credited with defining Network forensics as &quot;the capture, recording, and analysis of network events in order to discover the source of security attacks or other problem incidents&quot;.\r\nCompared to computer forensics, where evidence is usually preserved on disk, network data is more volatile and unpredictable. Investigators often only have material to examine if packet filters, firewalls, and intrusion detection systems were set up to anticipate breaches of security.\r\nSystems used to collect network data for forensics use usually come in two forms:\r\n<ul><li>&quot;Catch-it-as-you-can&quot; – This is where all packets passing through a certain traffic point are captured and written to storage with analysis being done subsequently in batch mode. This approach requires large amounts of storage.</li><li>&quot;Stop, look and listen&quot; – This is where each packet is analyzed in a rudimentary way in memory and only certain information saved for future analysis. This approach requires a faster processor to keep up with incoming traffic.</li></ul>","materialsDescription":" <span style=\"font-weight: bold;\">Why is network forensics important?</span>\r\nNetwork forensics is important because so many common attacks entail some type of misuse of network resources.\r\n<span style=\"font-weight: bold;\">What are the different ways in which the network can be attacked?</span>\r\nAttacks typically target availability confidentiality and integrity.

It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application. As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based.

This solution is less expensive than a network-based WAF and offers more customizability. The downside of a host-based WAF is the consumption of local server resources, implementation complexity, and maintenance costs. These components typically require engineering time, and may be costly.</li><li><span style=\"font-weight: bold; \">Cloud-based WAFs</span> offer an affordable option that is very easy to implement; they usually offer a turnkey installation that is as simple as a change in DNS to redirect traffic. Cloud-based WAFs also have a minimal upfront cost, as users pay monthly or annually for security as a service. Cloud-based WAFs can also offer a solution that is consistently updated to protect against the newest threats without any additional work or cost on the user’s end. The drawback of a cloud-based WAF is that users hand over the responsibility to a third-party, therefore some features of the WAF may be a black box to them. </li></ul>\r\n<p class=\"align-left\">&nbsp;</p>\r\n\r\n","materialsDescription":"<p class=\"align-center\"><span style=\"color: rgb(97, 97, 97); \"><span style=\"font-weight: bold; \">What types of attack WAF prevents?</span></span></p>\r\n<p class=\"align-left\"><span style=\"color: rgb(97, 97, 97); \">WAFs can prevent many attacks, including:</span></p>\r\n<ul><li><span style=\"color: rgb(97, 97, 97); \">Cross-site Scripting (XSS) — Attackers inject client-side scripts into web pages viewed by other users.</span></li><li><span style=\"color: rgb(97, 97, 97); \">SQL injection — Malicious code is inserted or injected into an web entry field that allows attackers to compromise the application and underlying systems.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Cookie poisoning — Modification of a cookie to gain unauthorized information about the user for purposes such as identity theft.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Unvalidated input — Attackers tamper with HTTP request (including the url, headers and form fields) to bypass the site’s security mechanisms.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Layer 7 DoS — An HTTP flood attack that utilizes valid requests in typical URL data retrievals.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Web scraping — Data scraping used for extracting data from websites.</span><span style=\"font-weight: bold; \"></span></li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What are some WAFs Benefits?</span></p>\r\nWeb app firewall prevents attacks that try to take advantage of the vulnerabilities in web-based applications. The vulnerabilities are common in legacy applications or applications with poor coding or designs. WAFs handle the code deficiencies with custom rules or policies.\r\nIntelligent WAFs provide real-time insights into application traffic, performance, security and threat landscape. This visibility gives administrators the flexibility to respond to the most sophisticated attacks on protected applications.\r\nWhen the Open Web Application Security Project identifies the OWASP top vulnerabilities, WAFs allow administrators to create custom security rules to combat the list of potential attack methods. An intelligent WAF analyzes the security rules matching a particular transaction and provides a real-time view as attack patterns evolve. Based on this intelligence, the WAF can reduce false positives.\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What is the difference between a firewall and a Web Application Firewall?</span></p>\r\nA traditional firewall protects the flow of information between servers while a web application firewall is able to filter traffic for a specific web application. Network firewalls and web application firewalls are complementary and can work together.\r\nTraditional security methods include network firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS). They are effective at blocking bad L3-L4 traffic at the perimeter on the lower end (L3-L4) of the Open Systems Interconnection (OSI) model. Traditional firewalls cannot detect attacks in web applications because they do not understand Hypertext Transfer Protocol (HTTP) which occurs at layer 7 of the OSI model. They also only allow the port that sends and receives requested web pages from an HTTP server to be open or closed. This is why web application firewalls are effective for preventing attacks like SQL injections, session hijacking and Cross-Site Scripting (XSS).","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAF_web_application_firewall.png"},{"id":483,"title":"Messaging Security","alias":"messaging-security","description":"<span style=\"font-weight: bold; \">Messaging security</span> is a subcategory of <span style=\"font-style: italic; \">unified threat management (UTM) </span>focused on securing and protecting an organization’s communication infrastructure.

This extra layer of security can help secure devices and block a wider range of viruses or malware attacks.\r\nMessaging security helps to ensure the confidentiality and authenticity of an organization’s communication methods. Confidentiality refers to making sure only the intended recipients are able to read the messages and authenticity refers to making sure the identity of each sender or recipient is verified.\r\nOftentimes, attackers aim to gain access to an entire network or system by infiltrating the messaging infrastructure. Implementing proper data and message security can minimize the chance of data leaks and identity theft.\r\n<span style=\"color: rgb(97, 97, 97); \">Encrypted messaging (also known as secure messaging) provides end-to-end encryption for user-to-user text messaging.

Computer viruses are often programmed to perform damaging actions — such as corrupting or deleting data. The longer a virus remains undetected on your machine, the greater the number of infected files that may be on your computer.\r\n<span style=\"font-weight: bold; \">Worms.</span> Worms are generally considered to be a subset of computer viruses — but with some specific differences:\r\n<ul><li>A worm is a computer program that replicates, but does not infect other files.</li><li>The worm will install itself once on a computer — and then look for a way to spread to other computers.</li><li>Whereas a virus is a set of code that adds itself to existing files, a worm exists as a separate, standalone file.</li></ul>\r\n<span style=\"font-weight: bold; \">What is a Trojan virus?</span>\r\nA Trojan is effectively a program that pretends to be legitimate software — but, when launched, it will perform a harmful action. Unlike computer viruses and worms, Trojans cannot spread by themselves. Typically, Trojans are installed secretly and they deliver their malicious payload without the user’s knowledge.\r\nCybercriminals use many different types of Trojans — and each has been designed to perform a specific malicious function. The most common are:\r\n<ul><li>Backdoor Trojans (these often include a keylogger)</li><li>Trojan Spies</li><li>Password stealing Trojans</li><li>Trojan Proxies — that convert your computer into a spam distribution machine</li></ul>\r\n<span style=\"font-weight: bold; \">Why are Trojan viruses called Trojans?</span>\r\nIn Greek mythology — during the Trojan war — the Greeks used subterfuge to enter the city of Troy. The Greeks constructed a massive wooden horse — and, unaware that the horse contained Greek soldiers, the Trojans pulled the horse into the city. At night, the Greek soldiers escaped from the horse and opened the city gates — for the Greek army to enter Troy.\r\nToday, Trojan viruses use subterfuge to enter unsuspecting users’ computers and devices.\r\n<span style=\"font-weight: bold; \">What is a Keylogger?</span>\r\nA keylogger is a program that can record what you type on your computer keyboard. Criminals use keyloggers to obtain confidential data — such as login details, passwords, credit card numbers, PINs and other items. Backdoor Trojans typically include an integrated keylogger.\r\n<span style=\"font-weight: bold; \">What is Phishing?</span>\r\nPhishing is a very specific type of cybercrime that is designed to trick you into disclosing valuable information — such as details about your bank account or credit cards. Often, cybercriminals will create a fake website that looks just like a legitimate site — such as a bank’s official website. The cybercriminal will try to trick you into visiting their fake site — typically by sending you an email that contains a hyperlink to the fake site. When you visit the fake website, it will generally ask you to type in confidential data — such as your login, password or PIN.\r\n<span style=\"font-weight: bold; \">What is Spyware?</span>\r\nSpyware is software that is designed to collect your data and send it to a third party — without your knowledge or consent. Spyware programs will often:\r\n<ul><li>Monitor the keys you press on your keyboard — using a keylogger</li><li>Collect confidential information — such as your passwords, credit card numbers, PIN numbers and more</li><li>Gather — or ‘harvest’ — email addresses from your computer</li><li>Track your Internet browsing habits</li></ul>\r\n<span style=\"font-weight: bold; \">What is a Rootkit?</span>\r\nRootkits are programs that hackers use in order to evade detection while trying to gain unauthorised access to a computer. Rootkits have been used increasingly as a form of stealth to hide Trojan virus activity. When installed on a computer, rootkits are invisible to the user and also take steps to avoid being detected by security software.\r\nThe fact that many people log into their computers with administrator rights — rather than creating a separate account with restricted access — makes it easier for cybercriminals to install a rootkit.\r\n<span style=\"font-weight: bold; \">What is a Botnet?</span>\r\nA botnet is a network of computers controlled by cybercriminals using a Trojan virus or other malicious program.\r\n<span style=\"font-weight: bold;\">What is a DDoS attack?</span>\r\nA Distributed-Denial-of-Service (DDoS) attack is similar to a DoS. However, a DDoS attack is conducted using multiple machines. Usually, for a DDoS attack, the hacker will use one security compromised computer as the ‘master’ machine that co-ordinates the attack by other ‘zombie machines’. Typically, the cybercriminal will compromise the security on the master and all of the zombie machines, by exploiting a vulnerability in an application on each computer — to install a Trojan or other piece of malicious code.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/security-web-application-security.png"},{"id":836,"title":"DRP - Digital Risk Protection","alias":"drp-digital-risk-protection","description":"Digital risks exist on social media and web channels, outside most organization's line of visibility.

It is a subset of endpoint security technology and a critical piece of an optimal security posture. EDR differs from other endpoint protection platforms (EPP) such as antivirus (AV) and anti-malware in that its primary focus isn't to automatically stop threats in the pre-execution phase on an endpoint. Rather, EDR is focused on providing the right endpoint visibility with the right insights to help security analysts discover, investigate and respond to very advanced threats and broader attack campaigns stretching across multiple endpoints. Many EDR tools, however, combine EDR and EPP.\r\nWhile small and mid-market organizations are increasingly turning to EDR technology for more advanced endpoint protection, many lack the resources to maximize the benefits of the technology. Utilizing advanced EDR features such as forensic analysis, behavioral monitoring and artificial intelligence (AI) is labor and resource intensive, requiring the attention of dedicated security professionals.\r\nA managed endpoint security service combines the latest technology, an around-the-clock team of certified CSOC experts and up-to-the-minute industry intelligence for a cost-effective monthly subscription.

It’s important to find EDR software that can provide the highest level of protection while requiring the least amount of effort and investment — adding value to your security team without draining resources. Here are the six key aspects of EDR you should look for:\r\n<span style=\"font-weight: bold;\">1. Visibility:</span> Real-time visibility across all your endpoints allows you to view adversary activities, even as they attempt to breach your environment and stop them immediately.\r\n<span style=\"font-weight: bold;\">2. Threat Database:</span> Effective EDR requires massive amounts of telemetry collected from endpoints and enriched with context so it can be mined for signs of attack with a variety of analytic techniques.\r\n<span style=\"font-weight: bold;\">3. Behavioral Protection:</span> Relying solely on signature-based methods or indicators of compromise (IOCs) lead to the “silent failure” that allows data breaches to occur. Effective endpoint detection and response requires behavioral approaches that search for indicators of attack (IOAs), so you are alerted of suspicious activities before a compromise can occur.\r\n<span style=\"font-weight: bold;\">4. Insight and Intelligence:</span> An endpoint detection and response solution that integrates threat intelligence can provide context, including details on the attributed adversary that is attacking you or other information about the attack.\r\n<span style=\"font-weight: bold;\">5.

These networks are responsible for providing automated control and remote human management of essential commodities and services such as water, natural gas, electricity and transportation to millions of people. They can also be used to improve the efficiencies and quality in other less essential (but some would say very important!) real-world processes such as snowmaking for ski resorts and beer brewing. SCADA is one of the most common types of industrial control systems (ICS).\r\nThese networks, just like any other network, are under threat from cyber-attacks that could bring down any part of the nation's critical infrastructure quickly and with dire consequences if the right security is not in place. Capital expenditure is another key concern; SCADA systems can cost an organization from tens of thousands to millions of dollars. For these reasons, it is essential that organizations implement robust SCADA security measures to protect their infrastructure and the millions of people that would be affected by the disruption caused by an external attack or internal error.\r\nSCADA security has evolved dramatically in recent years. Before computers, the only way to monitor a SCADA network was to deploy several people to each station to report back on the state of each system. In busier stations, technicians were stationed permanently to manually operate the network and communicate over telephone wires.\r\nIt wasn't until the introduction of the local area network (LAN) and improvements in system miniaturization that we started to see advances in SCADA development such as the distributed SCADA network. Next came networked systems that were able to communicate over a wide area network (WAN) and connect many more components together.\r\nFrom local companies to federal governments, every business or organization that works with SCADA systems are vulnerable to SCADA security threats. These threats can have wide-reaching effects on both the economy and the community. Specific threats to SCADA networks include the following:\r\n<span style=\"font-weight: bold;\">Hackers.</span> Individuals or groups with malicious intent could bring a SCADA network to its knees. By gaining access to key SCADA components, hackers could unleash chaos on an organization that can range from a disruption in services to cyber warfare.\r\n<span style=\"font-weight: bold;\">Malware.</span> Malware, including viruses, spyware and ransomware can pose a risk to SCADA systems. While malware may not be able to specifically target the network itself, it can still pose a threat to the key infrastructure that helps to manage the SCADA network. This includes mobile SCADA applications that are used to monitor and manage SCADA systems.\r\n<span style=\"font-weight: bold;\">Terrorists.</span> Where hackers are usually motivated by sordid gain, terrorists are driven by the desire to cause as much mayhem and damage as possible.\r\n<span style=\"font-weight: bold;\">Employees.</span> Insider threats can be just as damaging as external threats. From human error to a disgruntled employee or contractor, it is essential that SCADA security addresses these risks.\r\nManaging today's SCADA networks can be a challenge without the right security precautions in place. Many networks are still without the necessary detection and monitoring systems and this leaves them vulnerable to attack. Because SCADA network attacks exploit both cyber and physical vulnerabilities, it is critical to align cybersecurity measures accordingly.","materialsDescription":"<span style=\"font-weight: bold;\">What is the difference between ICS/SCADA cybersecurity and information security?</span>\r\nAutomated process control systems (SCADA) have a lot of differences from “traditional” corporate information systems: from the destination, specific data transfer protocols and equipment used and ending with the environment in which they operate. In corporate networks and systems, as a rule, the main protected resource is information that is processed, transmitted and stored in automated systems, and the main goal is to ensure its confidentiality. In ICS, the protected resource, first of all, is the technological process itself, and the main goal is to ensure its continuity (accessibility of all nodes) and integrity (including information transmitted between the nodes of the ICS). Moreover, the field of potential risks and threats to ICS, in comparison with corporate systems, expands with risks of potential damage to life and health of personnel and the public, damage to the environment and infrastructure. That is why it is incorrect to talk about “information security” in relation to ICS/SCADA. In English sources, the term “cybersecurity” is used for this, a direct translation of which (cybersecurity) is increasingly found in our market in relation to the protection of process control systems.\r\n<span style=\"font-weight: bold;\">Is it really necessary?</span>\r\nIt is necessary. There are a number of myths about process control systems, for example: “process control systems are completely isolated from the outside world”, “process control systems are too specific for someone to crack”, “process control systems are reliably protected by the developer”, or even “No one will ever try us, hacking us is not interesting. ” All this is no longer true. Many modern distributed process control systems have one or another connection with the corporate network, even if the system owners are unaware of this. Communication with the outside world greatly simplifies the task of the attacker, but does not remain the only possible option. Automated process control software and data transfer protocols are, as a rule, very, very insecure against cyber threats. This is evidenced by numerous articles and reports of experts involved in the study of the protection of industrial control systems and penetration tests. The PHDays III section on hacking automated process control systems impressed even ardent skeptics. Well, and, of course, the argument “they have NOT attacked us, therefore they will not” - can hardly be considered seriously. Everyone has heard about Stuxnet, which dispelled almost all the myths about the safety of ICS at once.\r\n<span style=\"font-weight: bold;\">Who needs this?</span>\r\nWith the phrase ICS/SCADA, most imagine huge plants, automated CNC machines or something similar. However, the application of process control systems is not limited to these objects - in the modern age of automation, process control systems are used everywhere: from large production facilities, the oil and gas industry, transport management to smart home systems. And, by the way, with the protection of the latter, as a rule, everything can be much worse, because the developer silently and imperceptibly shifts responsibility to the shoulders of the user.\r\nOf course, some of the objects with automated process control systems are more interesting for attackers, others less. But, given the ever-growing number of vulnerabilities discovered and published in the ICS, the spread of &quot;exclusive&quot; (written for specific protocols and ICS software) malware, considering your system safe &quot;by default&quot; is unreasonable.\r\n<span style=\"font-weight: bold;\">Are ICS and SCADA the same thing?</span>\r\nNo. SCADA systems (supervisory control and data acquisition, supervisory control and data collection) are part of the control system. Usually, a SCADA system means centralized control and management systems with the participation of a person as a whole system or a complex of industrial control systems. SCADA is the central link between people (human-machine interfaces) and PLC levels (programmable logic controller) or RTU (remote terminal unit).\r\n<span style=\"font-weight: bold;\">What is ICS/SCADA cybersecurity?</span>\r\nIn fact, ICS cybersecurity is a process similar to “information security” in a number of properties, but very different in details. And the devil, as you know, lies in them. ICS/SCADA also has similar information security-related processes: asset inventory, risk analysis and assessment, threat analysis, security management, change management, incident response, continuity, etc. But these processes themselves are different.<br />The cyber security of ICSs has the same basic target qualities - confidentiality, integrity and accessibility, but the significance and point of application for them are completely different. It should be remembered that in ICS/SCADA we, first of all, protect the technological process. Beyond this - from the risks of damage to human health and life and the environment.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_SCADA_Cyber_Security.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},"dbappsecurity-das-waf":{"id":2182,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/DAS-WAF.jpg","logo":true,"scheme":false,"title":"DBAPPSecurity DAS-WAF","vendorVerified":0,"rating":"1.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"dbappsecurity-das-waf","companyTitle":"DBAPPSecurity","companyTypes":["vendor"],"companyId":4562,"companyAlias":"dbappsecurity","description":"<p>DBAPPSecurity Web Application Firewall (DAS-WAF), which is the innovative product with our intellectual property, protects Web Application from cyber attacks and control the critical data.

It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application. As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based.

This solution is less expensive than a network-based WAF and offers more customizability. The downside of a host-based WAF is the consumption of local server resources, implementation complexity, and maintenance costs. These components typically require engineering time, and may be costly.</li><li><span style=\"font-weight: bold; \">Cloud-based WAFs</span> offer an affordable option that is very easy to implement; they usually offer a turnkey installation that is as simple as a change in DNS to redirect traffic. Cloud-based WAFs also have a minimal upfront cost, as users pay monthly or annually for security as a service. Cloud-based WAFs can also offer a solution that is consistently updated to protect against the newest threats without any additional work or cost on the user’s end. The drawback of a cloud-based WAF is that users hand over the responsibility to a third-party, therefore some features of the WAF may be a black box to them. </li></ul>\r\n<p class=\"align-left\">&nbsp;</p>\r\n\r\n","materialsDescription":"<p class=\"align-center\"><span style=\"color: rgb(97, 97, 97); \"><span style=\"font-weight: bold; \">What types of attack WAF prevents?</span></span></p>\r\n<p class=\"align-left\"><span style=\"color: rgb(97, 97, 97); \">WAFs can prevent many attacks, including:</span></p>\r\n<ul><li><span style=\"color: rgb(97, 97, 97); \">Cross-site Scripting (XSS) — Attackers inject client-side scripts into web pages viewed by other users.</span></li><li><span style=\"color: rgb(97, 97, 97); \">SQL injection — Malicious code is inserted or injected into an web entry field that allows attackers to compromise the application and underlying systems.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Cookie poisoning — Modification of a cookie to gain unauthorized information about the user for purposes such as identity theft.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Unvalidated input — Attackers tamper with HTTP request (including the url, headers and form fields) to bypass the site’s security mechanisms.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Layer 7 DoS — An HTTP flood attack that utilizes valid requests in typical URL data retrievals.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Web scraping — Data scraping used for extracting data from websites.</span><span style=\"font-weight: bold; \"></span></li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What are some WAFs Benefits?</span></p>\r\nWeb app firewall prevents attacks that try to take advantage of the vulnerabilities in web-based applications. The vulnerabilities are common in legacy applications or applications with poor coding or designs. WAFs handle the code deficiencies with custom rules or policies.\r\nIntelligent WAFs provide real-time insights into application traffic, performance, security and threat landscape. This visibility gives administrators the flexibility to respond to the most sophisticated attacks on protected applications.\r\nWhen the Open Web Application Security Project identifies the OWASP top vulnerabilities, WAFs allow administrators to create custom security rules to combat the list of potential attack methods. An intelligent WAF analyzes the security rules matching a particular transaction and provides a real-time view as attack patterns evolve. Based on this intelligence, the WAF can reduce false positives.\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What is the difference between a firewall and a Web Application Firewall?</span></p>\r\nA traditional firewall protects the flow of information between servers while a web application firewall is able to filter traffic for a specific web application. Network firewalls and web application firewalls are complementary and can work together.\r\nTraditional security methods include network firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS). They are effective at blocking bad L3-L4 traffic at the perimeter on the lower end (L3-L4) of the Open Systems Interconnection (OSI) model. Traditional firewalls cannot detect attacks in web applications because they do not understand Hypertext Transfer Protocol (HTTP) which occurs at layer 7 of the OSI model. They also only allow the port that sends and receives requested web pages from an HTTP server to be open or closed. This is why web application firewalls are effective for preventing attacks like SQL injections, session hijacking and Cross-Site Scripting (XSS).","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAF_web_application_firewall.png"},{"id":546,"title":"WAF-web application firewall appliance","alias":"waf-web-application-firewall-appliance","description":"A web application firewall is a special type of application firewall that applies specifically to web applications. It is deployed in front of web applications and analyzes bi-directional web-based (HTTP) traffic - detecting and blocking anything malicious. The OWASP provides a broad technical definition for a WAF as “a security solution on the web application level which - from a technical point of view - does not depend on the application itself.” According to the PCI DSS Information Supplement for requirement 6.6, a WAF is defined as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.” In other words, a WAF can be a physical appliance that prevents vulnerabilities in web applications from being exploited by outside threats. These vulnerabilities may be because the application itself is a legacy type or it was insufficiently coded by design. The WAF addresses these code shortcomings by special configurations of rule sets, also known as policies.\r\nPreviously unknown vulnerabilities can be discovered through penetration testing or via a vulnerability scanner. A web application vulnerability scanner, also known as a web application security scanner, is defined in the SAMATE NIST 500-269 as “an automated program that examines web applications for potential security vulnerabilities. In addition to searching for web application-specific vulnerabilities, the tools also look for software coding errors.” Resolving vulnerabilities is commonly referred to as remediation. Corrections to the code can be made in the application but typically a more prompt response is necessary. In these situations, the application of a custom policy for a unique web application vulnerability to provide a temporary but immediate fix (known as a virtual patch) may be necessary.\r\nWAFs are not an ultimate security solution, rather they are meant to be used in conjunction with other network perimeter security solutions such as network firewalls and intrusion prevention systems to provide a holistic defense strategy.\r\nWAFs typically follow a positive security model, a negative security model, or a combination of both as mentioned by the SANS Institute. WAFs use a combination of rule-based logic, parsing, and signatures to detect and prevent attacks such as cross-site scripting and SQL injection. The OWASP produces a list of the top ten web application security flaws. All commercial WAF offerings cover these ten flaws at a minimum. There are non-commercial options as well. As mentioned earlier, the well-known open source WAF engine called ModSecurity is one of these options. A WAF engine alone is insufficient to provide adequate protection, therefore OWASP along with Trustwave's Spiderlabs help organize and maintain a Core-Rule Set via GitHub to use with the ModSecurity WAF engine.","materialsDescription":"A Web Application Firewall or WAF provides security for online services from malicious Internet traffic.

It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application. As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based.

It is deployed in front of web applications and analyzes bi-directional web-based (HTTP) traffic - detecting and blocking anything malicious. The OWASP provides a broad technical definition for a WAF as “a security solution on the web application level which - from a technical point of view - does not depend on the application itself.” According to the PCI DSS Information Supplement for requirement 6.6, a WAF is defined as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.” In other words, a WAF can be a physical appliance that prevents vulnerabilities in web applications from being exploited by outside threats. These vulnerabilities may be because the application itself is a legacy type or it was insufficiently coded by design. The WAF addresses these code shortcomings by special configurations of rule sets, also known as policies.\r\nPreviously unknown vulnerabilities can be discovered through penetration testing or via a vulnerability scanner. A web application vulnerability scanner, also known as a web application security scanner, is defined in the SAMATE NIST 500-269 as “an automated program that examines web applications for potential security vulnerabilities. In addition to searching for web application-specific vulnerabilities, the tools also look for software coding errors.” Resolving vulnerabilities is commonly referred to as remediation. Corrections to the code can be made in the application but typically a more prompt response is necessary. In these situations, the application of a custom policy for a unique web application vulnerability to provide a temporary but immediate fix (known as a virtual patch) may be necessary.\r\nWAFs are not an ultimate security solution, rather they are meant to be used in conjunction with other network perimeter security solutions such as network firewalls and intrusion prevention systems to provide a holistic defense strategy.\r\nWAFs typically follow a positive security model, a negative security model, or a combination of both as mentioned by the SANS Institute. WAFs use a combination of rule-based logic, parsing, and signatures to detect and prevent attacks such as cross-site scripting and SQL injection. The OWASP produces a list of the top ten web application security flaws. All commercial WAF offerings cover these ten flaws at a minimum. There are non-commercial options as well. As mentioned earlier, the well-known open source WAF engine called ModSecurity is one of these options. A WAF engine alone is insufficient to provide adequate protection, therefore OWASP along with Trustwave's Spiderlabs help organize and maintain a Core-Rule Set via GitHub to use with the ModSecurity WAF engine.","materialsDescription":"A Web Application Firewall or WAF provides security for online services from malicious Internet traffic.

This is why web application firewalls are effective for preventing attacks like SQL injections, session hijacking and Cross-Site Scripting (XSS).","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAF_web_application_firewall.png"},{"id":546,"title":"WAF-web application firewall appliance","alias":"waf-web-application-firewall-appliance","description":"A web application firewall is a special type of application firewall that applies specifically to web applications. It is deployed in front of web applications and analyzes bi-directional web-based (HTTP) traffic - detecting and blocking anything malicious. The OWASP provides a broad technical definition for a WAF as “a security solution on the web application level which - from a technical point of view - does not depend on the application itself.” According to the PCI DSS Information Supplement for requirement 6.6, a WAF is defined as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.” In other words, a WAF can be a physical appliance that prevents vulnerabilities in web applications from being exploited by outside threats. These vulnerabilities may be because the application itself is a legacy type or it was insufficiently coded by design. The WAF addresses these code shortcomings by special configurations of rule sets, also known as policies.\r\nPreviously unknown vulnerabilities can be discovered through penetration testing or via a vulnerability scanner. A web application vulnerability scanner, also known as a web application security scanner, is defined in the SAMATE NIST 500-269 as “an automated program that examines web applications for potential security vulnerabilities. In addition to searching for web application-specific vulnerabilities, the tools also look for software coding errors.” Resolving vulnerabilities is commonly referred to as remediation. Corrections to the code can be made in the application but typically a more prompt response is necessary. In these situations, the application of a custom policy for a unique web application vulnerability to provide a temporary but immediate fix (known as a virtual patch) may be necessary.\r\nWAFs are not an ultimate security solution, rather they are meant to be used in conjunction with other network perimeter security solutions such as network firewalls and intrusion prevention systems to provide a holistic defense strategy.\r\nWAFs typically follow a positive security model, a negative security model, or a combination of both as mentioned by the SANS Institute. WAFs use a combination of rule-based logic, parsing, and signatures to detect and prevent attacks such as cross-site scripting and SQL injection. The OWASP produces a list of the top ten web application security flaws. All commercial WAF offerings cover these ten flaws at a minimum. There are non-commercial options as well. As mentioned earlier, the well-known open source WAF engine called ModSecurity is one of these options. A WAF engine alone is insufficient to provide adequate protection, therefore OWASP along with Trustwave's Spiderlabs help organize and maintain a Core-Rule Set via GitHub to use with the ModSecurity WAF engine.","materialsDescription":"A Web Application Firewall or WAF provides security for online services from malicious Internet traffic. WAFs detect and filter out threats such as the OWASP Top 10, which could degrade, compromise or bring down online applications.\r\n<span style=\"font-weight: bold;\">What are Web Application Firewalls?</span>\r\nWeb application firewalls assist load balancing by examining HTTP traffic before it reaches the application server. They also protect against web application vulnerability and unauthorized transfer of data from the web server at a time when security breaches are on the rise. According to the Verizon Data Breach Investigations Report, web application attacks were the most prevalent breaches in 2017 and 2018.\r\nThe PCI Security Standards Council defines a web application firewall as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\n<span style=\"font-weight: bold;\">How does a Web Application Firewall wWork?</span>\r\nA web application firewall (WAF) intercepts and inspects all HTTP requests using a security model based on a set of customized policies to weed out bogus traffic. WAFs block bad traffic outright or can challenge a visitor with a CAPTCHA test that humans can pass but a malicious bot or computer program cannot.\r\nWAFs follow rules or policies customized to specific vulnerabilities. As a result, this is how WAFs prevent DDoS attacks. Creating the rules on a traditional WAF can be complex and require expert administration. The Open Web Application Security Project maintains a list of the OWASP top web application security flaws for WAF policies to address.\r\nWAFs come in the form of hardware appliances, server-side software, or filter traffic as-a-service. WAFs can be considered as reverse proxies i.e. the opposite of a proxy server. Proxy servers protect devices from malicious applications, while WAFs protect web applications from malicious endpoints.\r\n<span style=\"font-weight: bold;\">What Are Some Web Application Firewall Benefits?</span>\r\nA web application firewall (WAF) prevents attacks that try to take advantage of the vulnerabilities in web-based applications. The vulnerabilities are common in legacy applications or applications with poor coding or designs. WAFs handle the code deficiencies with custom rules or policies.\r\nIntelligent WAFs provide real-time insights into application traffic, performance, security and threat landscape. This visibility gives administrators the flexibility to respond to the most sophisticated attacks on protected applications.\r\nWhen the Open Web Application Security Project identifies the OWASP top vulnerabilities, WAFs allow administrators to create custom security rules to combat the list of potential attack methods. An intelligent WAF analyzes the security rules matching a particular transaction and provides a real-time view as attack patterns evolve. Based on this intelligence, the WAF can reduce false positives.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between a Firewall and a Web Application Firewall?</span>\r\nA traditional firewall protects the flow of information between servers while a web application firewall is able to filter traffic for a specific web application. Network firewalls and web application firewalls are complementary and can work together.\r\nTraditional security methods include network firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS). They are effective at blocking bad L3-L4 traffic at the perimeter on the lower end (L3-L4) of the Open Systems Interconnection (OSI) model. Traditional firewalls cannot detect attacks in web applications because they do not understand Hypertext Transfer Protocol (HTTP) which occurs at layer 7 of the OSI model. They also only allow the port that sends and receives requested web pages from an HTTP server to be open or closed. This is why web application firewalls are effective for preventing attacks like SQL injections, session hijacking and Cross-Site Scripting (XSS).\r\n<span style=\"font-weight: bold;\">When Should You Use a Web Application Firewall?</span>\r\nAny business that uses a website to generate revenue should use a web application firewall to protect business data and services. Organizations that use online vendors should especially deploy web application firewalls because the security of outside groups cannot be controlled or trusted.\r\n<span style=\"font-weight: bold;\">How Do You Use a Web Application Firewall?</span>\r\nA web application firewall requires correct positioning, configuration, administration and monitoring. Web application firewall installation must include the following four steps: secure, monitor, test and improve. This should be a continuous process to ensure application specific protection.<br />The configuration of the firewall should be determined by the business rules and guardrails by the company’s security policy. This approach will allow the rules and filters in the web application firewall to define themselves.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAF_web_application_firewall_appliance.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},"f5-silverline-web-application-firewall":{"id":1604,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/F5_Networks.png","logo":true,"scheme":false,"title":"F5 Silverline Web Application Firewall","vendorVerified":0,"rating":"1.70","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":1,"alias":"f5-silverline-web-application-firewall","companyTitle":"F5 Networks","companyTypes":["vendor"],"companyId":2749,"companyAlias":"f5-networks","description":"F5 Silverline Web Application Firewall is a cloud based service with 24x7x365 support from highly specialized security experts.

Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based.

Cloud-based WAFs also have a minimal upfront cost, as users pay monthly or annually for security as a service. Cloud-based WAFs can also offer a solution that is consistently updated to protect against the newest threats without any additional work or cost on the user’s end. The drawback of a cloud-based WAF is that users hand over the responsibility to a third-party, therefore some features of the WAF may be a black box to them. </li></ul>\r\n<p class=\"align-left\">&nbsp;</p>\r\n\r\n","materialsDescription":"<p class=\"align-center\"><span style=\"color: rgb(97, 97, 97); \"><span style=\"font-weight: bold; \">What types of attack WAF prevents?</span></span></p>\r\n<p class=\"align-left\"><span style=\"color: rgb(97, 97, 97); \">WAFs can prevent many attacks, including:</span></p>\r\n<ul><li><span style=\"color: rgb(97, 97, 97); \">Cross-site Scripting (XSS) — Attackers inject client-side scripts into web pages viewed by other users.</span></li><li><span style=\"color: rgb(97, 97, 97); \">SQL injection — Malicious code is inserted or injected into an web entry field that allows attackers to compromise the application and underlying systems.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Cookie poisoning — Modification of a cookie to gain unauthorized information about the user for purposes such as identity theft.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Unvalidated input — Attackers tamper with HTTP request (including the url, headers and form fields) to bypass the site’s security mechanisms.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Layer 7 DoS — An HTTP flood attack that utilizes valid requests in typical URL data retrievals.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Web scraping — Data scraping used for extracting data from websites.</span><span style=\"font-weight: bold; \"></span></li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What are some WAFs Benefits?</span></p>\r\nWeb app firewall prevents attacks that try to take advantage of the vulnerabilities in web-based applications.

It is deployed in front of web applications and analyzes bi-directional web-based (HTTP) traffic - detecting and blocking anything malicious. The OWASP provides a broad technical definition for a WAF as “a security solution on the web application level which - from a technical point of view - does not depend on the application itself.” According to the PCI DSS Information Supplement for requirement 6.6, a WAF is defined as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.” In other words, a WAF can be a physical appliance that prevents vulnerabilities in web applications from being exploited by outside threats. These vulnerabilities may be because the application itself is a legacy type or it was insufficiently coded by design. The WAF addresses these code shortcomings by special configurations of rule sets, also known as policies.\r\nPreviously unknown vulnerabilities can be discovered through penetration testing or via a vulnerability scanner. A web application vulnerability scanner, also known as a web application security scanner, is defined in the SAMATE NIST 500-269 as “an automated program that examines web applications for potential security vulnerabilities. In addition to searching for web application-specific vulnerabilities, the tools also look for software coding errors.” Resolving vulnerabilities is commonly referred to as remediation. Corrections to the code can be made in the application but typically a more prompt response is necessary. In these situations, the application of a custom policy for a unique web application vulnerability to provide a temporary but immediate fix (known as a virtual patch) may be necessary.\r\nWAFs are not an ultimate security solution, rather they are meant to be used in conjunction with other network perimeter security solutions such as network firewalls and intrusion prevention systems to provide a holistic defense strategy.\r\nWAFs typically follow a positive security model, a negative security model, or a combination of both as mentioned by the SANS Institute. WAFs use a combination of rule-based logic, parsing, and signatures to detect and prevent attacks such as cross-site scripting and SQL injection. The OWASP produces a list of the top ten web application security flaws. All commercial WAF offerings cover these ten flaws at a minimum. There are non-commercial options as well. As mentioned earlier, the well-known open source WAF engine called ModSecurity is one of these options. A WAF engine alone is insufficient to provide adequate protection, therefore OWASP along with Trustwave's Spiderlabs help organize and maintain a Core-Rule Set via GitHub to use with the ModSecurity WAF engine.","materialsDescription":"A Web Application Firewall or WAF provides security for online services from malicious Internet traffic. WAFs detect and filter out threats such as the OWASP Top 10, which could degrade, compromise or bring down online applications.\r\n<span style=\"font-weight: bold;\">What are Web Application Firewalls?</span>\r\nWeb application firewalls assist load balancing by examining HTTP traffic before it reaches the application server. They also protect against web application vulnerability and unauthorized transfer of data from the web server at a time when security breaches are on the rise. According to the Verizon Data Breach Investigations Report, web application attacks were the most prevalent breaches in 2017 and 2018.\r\nThe PCI Security Standards Council defines a web application firewall as “a security policy enforcement point positioned between a web application and the client endpoint.

WAFs block bad traffic outright or can challenge a visitor with a CAPTCHA test that humans can pass but a malicious bot or computer program cannot.\r\nWAFs follow rules or policies customized to specific vulnerabilities. As a result, this is how WAFs prevent DDoS attacks. Creating the rules on a traditional WAF can be complex and require expert administration. The Open Web Application Security Project maintains a list of the OWASP top web application security flaws for WAF policies to address.\r\nWAFs come in the form of hardware appliances, server-side software, or filter traffic as-a-service. WAFs can be considered as reverse proxies i.e. the opposite of a proxy server. Proxy servers protect devices from malicious applications, while WAFs protect web applications from malicious endpoints.\r\n<span style=\"font-weight: bold;\">What Are Some Web Application Firewall Benefits?</span>\r\nA web application firewall (WAF) prevents attacks that try to take advantage of the vulnerabilities in web-based applications.

This includes blocking technical attacks such as SQL injection, cross-site scripting and remote file inclusion that exploit vulnerabilities in web applications; business logic attacks such as site scraping and comment spam; botnets and DDoS attacks; and preventing account takeover attempts in real-time, before fraudulent transactions can be performed.\r\n\r\nDYNAMIC APPLICATION PROFILING\r\n\r\nWAF uses patented Dynamic Application Profiling to learn all aspects of web applications, including the directories, URLs, parameters, and acceptable user inputs to detect attacks with exceptional accuracy and block only bad parties, while eliminating impact to legitimate customers. WAF mitigates both technical attacks such as DDoS and SQL injection, as well as non-technical attacks such as comment spamming and site scraping.\r\n\r\nGRANULAR CORRELATION POLICIES REDUCE FALSE POSITIVES\r\n\r\nWAF distinguishes attacks from unusual, but legitimate, behavior by correlating web requests across security layers and over time. Correlated Attack Validation capability examines multiple attributes such as HTTP protocol conformance, profile violations, signatures, special characters, and user reputation, to accurately alert on or block attacks with the lowest rate of false positives in the industry.\r\n\r\nFLEXIBLE DEPLOYMENT OPTIONS\r\n\r\nWAF can be deployed as a physical or virtual appliance on-premises, and as a virtual image on Amazon Web Services or Microsoft Azure. Physical appliance deployments are particularly flexible in that they allow WAF to run transparently, requiring virtually no changes to the customer’s network. And granular policy controls enable superior accuracy and unequaled control to match each organization’s specific protection requirements.\r\n\r\nDEEP THREAT INTELLIGENCE\r\n\r\nTo protect against today’s well resourced cyber-criminals, it is vital to have an advanced warning system that is aware of and protects against constantly evolving web-based attacks. Imperva ThreatRadar updates WAF with real-time threat intelligence crowd-sourced from around the world and curated by Imperva Application Defense Center. ThreatRadar provides better protection, improves WAF accuracy, and makes the security team more efficient by proactively filtering traffic from known bad sources so the security team can focus on what is really important. The following ThreatRadar intelligence feeds are available: Reputation Services: Filters traffic based upon latest, real-time reputation of source Community Defense: Adds unique threat intelligence crowd-sourced from Imperva users Bot Protection: Detects botnet clients and application DDoS attacks Account Takeover Protection: Protects website user accounts from attack and takeover Fraud Prevention: Simplifies deployment of best-in-class partner fraud prevention solutions VIRTUAL PATCHING WAF can perform “virtual patching” for your web applications via vulnerability scanner integration. Instead of leaving a web application exposed to attack for weeks or months while code is modified after discovering a vulnerability, virtual patching actively protects web applications from attacks to reduce the window of exposure, and decreases the costs of emergency fix cycles until you are able to patch them.\r\n\r\nCUSTOMIZABLE REPORTS FOR COMPLIANCE AND FORENSICS\r\n\r\nWAF rich graphical reporting capabilities enable customers to easily understand security status and meet regulatory compliance. WAF provides both pre-defined and fully-customizable reports. This enables you to quickly assess your security status and streamline demonstration of compliance with PCI, SOX, HIPAA and FISMA and other compliance standards.\r\n\r\nMONITORING FOR IN-DEPTH ANALYSIS OF ATTACKS\r\n\r\nAlerts can be easily searched, sorted, and directly linked to corresponding security rules. WAF monitoring and reporting framework provides instant visibility into security, compliance, and content delivery concerns. A real-time dashboard provides a high-level view of system status and security events.","shortDescription":"Imperva SecureSphere Web Application Firewall (WAF) analyzes all user access to your business-critical web applications and protects your applications and data from cyber attacks.","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":true,"bonus":100,"usingCount":20,"sellingCount":18,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"Imperva Web Application Firewall","keywords":"SecureSphere, attacks, from, applications, such, security, your, with","description":"\r\nImperva Web Application Firewall (WAF) analyzes all user access to your business-critical web applications and protects your applications and data from cyber attacks.

It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application. As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based.

This solution is less expensive than a network-based WAF and offers more customizability. The downside of a host-based WAF is the consumption of local server resources, implementation complexity, and maintenance costs. These components typically require engineering time, and may be costly.</li><li><span style=\"font-weight: bold; \">Cloud-based WAFs</span> offer an affordable option that is very easy to implement; they usually offer a turnkey installation that is as simple as a change in DNS to redirect traffic. Cloud-based WAFs also have a minimal upfront cost, as users pay monthly or annually for security as a service. Cloud-based WAFs can also offer a solution that is consistently updated to protect against the newest threats without any additional work or cost on the user’s end. The drawback of a cloud-based WAF is that users hand over the responsibility to a third-party, therefore some features of the WAF may be a black box to them. </li></ul>\r\n<p class=\"align-left\">&nbsp;</p>\r\n\r\n","materialsDescription":"<p class=\"align-center\"><span style=\"color: rgb(97, 97, 97); \"><span style=\"font-weight: bold; \">What types of attack WAF prevents?</span></span></p>\r\n<p class=\"align-left\"><span style=\"color: rgb(97, 97, 97); \">WAFs can prevent many attacks, including:</span></p>\r\n<ul><li><span style=\"color: rgb(97, 97, 97); \">Cross-site Scripting (XSS) — Attackers inject client-side scripts into web pages viewed by other users.</span></li><li><span style=\"color: rgb(97, 97, 97); \">SQL injection — Malicious code is inserted or injected into an web entry field that allows attackers to compromise the application and underlying systems.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Cookie poisoning — Modification of a cookie to gain unauthorized information about the user for purposes such as identity theft.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Unvalidated input — Attackers tamper with HTTP request (including the url, headers and form fields) to bypass the site’s security mechanisms.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Layer 7 DoS — An HTTP flood attack that utilizes valid requests in typical URL data retrievals.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Web scraping — Data scraping used for extracting data from websites.</span><span style=\"font-weight: bold; \"></span></li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What are some WAFs Benefits?</span></p>\r\nWeb app firewall prevents attacks that try to take advantage of the vulnerabilities in web-based applications. The vulnerabilities are common in legacy applications or applications with poor coding or designs. WAFs handle the code deficiencies with custom rules or policies.\r\nIntelligent WAFs provide real-time insights into application traffic, performance, security and threat landscape. This visibility gives administrators the flexibility to respond to the most sophisticated attacks on protected applications.\r\nWhen the Open Web Application Security Project identifies the OWASP top vulnerabilities, WAFs allow administrators to create custom security rules to combat the list of potential attack methods. An intelligent WAF analyzes the security rules matching a particular transaction and provides a real-time view as attack patterns evolve. Based on this intelligence, the WAF can reduce false positives.\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What is the difference between a firewall and a Web Application Firewall?</span></p>\r\nA traditional firewall protects the flow of information between servers while a web application firewall is able to filter traffic for a specific web application. Network firewalls and web application firewalls are complementary and can work together.\r\nTraditional security methods include network firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS). They are effective at blocking bad L3-L4 traffic at the perimeter on the lower end (L3-L4) of the Open Systems Interconnection (OSI) model. Traditional firewalls cannot detect attacks in web applications because they do not understand Hypertext Transfer Protocol (HTTP) which occurs at layer 7 of the OSI model. They also only allow the port that sends and receives requested web pages from an HTTP server to be open or closed. This is why web application firewalls are effective for preventing attacks like SQL injections, session hijacking and Cross-Site Scripting (XSS).","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAF_web_application_firewall.png"},{"id":485,"title":"Web security","alias":"web-security","description":" Web security basically means protecting a website or web application by detecting, preventing and responding to cyber threats.\r\nWebsites and web applications are just as prone to security breaches as physical homes, stores, and government locations. Unfortunately, cybercrime happens every day, and great web security measures are needed to protect websites and web applications from becoming compromised.\r\nThat’s exactly what web security does – it is a system of protection measures and protocols that can protect your website or web application from being hacked or entered by unauthorized personnel. This integral division of Information Security is vital to the protection of websites, web applications, and web services. Anything that is applied over the Internet should have some form of web security to protect it.\r\nThere are a lot of factors that go into web security and web protection. Any website or application that is secure is surely backed by different types of checkpoints and techniques for keeping it safe.\r\nThere are a variety of security standards that must be followed at all times, and these standards are implemented and highlighted by the OWASP. Most experienced web developers from top cybersecurity companies will follow the standards of the OWASP as well as keep a close eye on the Web Hacking Incident Database to see when, how, and why different people are hacking different websites and services.\r\nEssential steps in protecting web apps from attacks include applying up-to-date encryption, setting proper authentication, continuously patching discovered vulnerabilities, avoiding data theft by having secure software development practices. The reality is that clever attackers may be competent enough to find flaws even in a fairly robust secured environment, and so a holistic security strategy is advised.\r\nThere are different types of technologies available for maintaining the best security standards. Some popular technical solutions for testing, building, and preventing threats include black and white box testing tools, fuzzing tools, WAF, security or vulnerability scanners, password cracking tools, and so on.","materialsDescription":" <span style=\"font-weight: bold; \">What is Malware?</span>\r\nThe name malware is short for ‘malicioussoftware’. Malware includes any software program that has been created to perform an unauthorised — and often harmful — action on a user’s device. Examples of malware include:\r\n<ul><li>Computer viruses</li><li>Word and Excel macro viruses</li><li>Boot sector viruses</li><li>Script viruses — including batch, Windows shell, Java and others</li><li>Keyloggers</li><li>Password stealers</li><li>Backdoor Trojan viruses</li><li>Other Trojan viruses</li><li>Crimeware</li><li>Spyware</li><li>Adware... and many other types of malicious software programs</li></ul>\r\n<span style=\"font-weight: bold; \">What is the difference between a computer virus and a worm?</span>\r\n<span style=\"font-weight: bold; \">Computer virus.</span> This is a type of malicious program that can replicate itself — so that it can spread from file to file on a computer, and can also spread from one computer to another. Computer viruses are often programmed to perform damaging actions — such as corrupting or deleting data. The longer a virus remains undetected on your machine, the greater the number of infected files that may be on your computer.\r\n<span style=\"font-weight: bold; \">Worms.</span> Worms are generally considered to be a subset of computer viruses — but with some specific differences:\r\n<ul><li>A worm is a computer program that replicates, but does not infect other files.</li><li>The worm will install itself once on a computer — and then look for a way to spread to other computers.</li><li>Whereas a virus is a set of code that adds itself to existing files, a worm exists as a separate, standalone file.</li></ul>\r\n<span style=\"font-weight: bold; \">What is a Trojan virus?</span>\r\nA Trojan is effectively a program that pretends to be legitimate software — but, when launched, it will perform a harmful action. Unlike computer viruses and worms, Trojans cannot spread by themselves. Typically, Trojans are installed secretly and they deliver their malicious payload without the user’s knowledge.\r\nCybercriminals use many different types of Trojans — and each has been designed to perform a specific malicious function. The most common are:\r\n<ul><li>Backdoor Trojans (these often include a keylogger)</li><li>Trojan Spies</li><li>Password stealing Trojans</li><li>Trojan Proxies — that convert your computer into a spam distribution machine</li></ul>\r\n<span style=\"font-weight: bold; \">Why are Trojan viruses called Trojans?</span>\r\nIn Greek mythology — during the Trojan war — the Greeks used subterfuge to enter the city of Troy. The Greeks constructed a massive wooden horse — and, unaware that the horse contained Greek soldiers, the Trojans pulled the horse into the city. At night, the Greek soldiers escaped from the horse and opened the city gates — for the Greek army to enter Troy.\r\nToday, Trojan viruses use subterfuge to enter unsuspecting users’ computers and devices.\r\n<span style=\"font-weight: bold; \">What is a Keylogger?</span>\r\nA keylogger is a program that can record what you type on your computer keyboard. Criminals use keyloggers to obtain confidential data — such as login details, passwords, credit card numbers, PINs and other items. Backdoor Trojans typically include an integrated keylogger.\r\n<span style=\"font-weight: bold; \">What is Phishing?</span>\r\nPhishing is a very specific type of cybercrime that is designed to trick you into disclosing valuable information — such as details about your bank account or credit cards. Often, cybercriminals will create a fake website that looks just like a legitimate site — such as a bank’s official website. The cybercriminal will try to trick you into visiting their fake site — typically by sending you an email that contains a hyperlink to the fake site. When you visit the fake website, it will generally ask you to type in confidential data — such as your login, password or PIN.\r\n<span style=\"font-weight: bold; \">What is Spyware?</span>\r\nSpyware is software that is designed to collect your data and send it to a third party — without your knowledge or consent. Spyware programs will often:\r\n<ul><li>Monitor the keys you press on your keyboard — using a keylogger</li><li>Collect confidential information — such as your passwords, credit card numbers, PIN numbers and more</li><li>Gather — or ‘harvest’ — email addresses from your computer</li><li>Track your Internet browsing habits</li></ul>\r\n<span style=\"font-weight: bold; \">What is a Rootkit?</span>\r\nRootkits are programs that hackers use in order to evade detection while trying to gain unauthorised access to a computer. Rootkits have been used increasingly as a form of stealth to hide Trojan virus activity. When installed on a computer, rootkits are invisible to the user and also take steps to avoid being detected by security software.\r\nThe fact that many people log into their computers with administrator rights — rather than creating a separate account with restricted access — makes it easier for cybercriminals to install a rootkit.\r\n<span style=\"font-weight: bold; \">What is a Botnet?</span>\r\nA botnet is a network of computers controlled by cybercriminals using a Trojan virus or other malicious program.\r\n<span style=\"font-weight: bold;\">What is a DDoS attack?</span>\r\nA Distributed-Denial-of-Service (DDoS) attack is similar to a DoS. However, a DDoS attack is conducted using multiple machines. Usually, for a DDoS attack, the hacker will use one security compromised computer as the ‘master’ machine that co-ordinates the attack by other ‘zombie machines’. Typically, the cybercriminal will compromise the security on the master and all of the zombie machines, by exploiting a vulnerability in an application on each computer — to install a Trojan or other piece of malicious code.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/security-web-application-security.png"},{"id":546,"title":"WAF-web application firewall appliance","alias":"waf-web-application-firewall-appliance","description":"A web application firewall is a special type of application firewall that applies specifically to web applications. It is deployed in front of web applications and analyzes bi-directional web-based (HTTP) traffic - detecting and blocking anything malicious. The OWASP provides a broad technical definition for a WAF as “a security solution on the web application level which - from a technical point of view - does not depend on the application itself.” According to the PCI DSS Information Supplement for requirement 6.6, a WAF is defined as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.” In other words, a WAF can be a physical appliance that prevents vulnerabilities in web applications from being exploited by outside threats. These vulnerabilities may be because the application itself is a legacy type or it was insufficiently coded by design. The WAF addresses these code shortcomings by special configurations of rule sets, also known as policies.\r\nPreviously unknown vulnerabilities can be discovered through penetration testing or via a vulnerability scanner. A web application vulnerability scanner, also known as a web application security scanner, is defined in the SAMATE NIST 500-269 as “an automated program that examines web applications for potential security vulnerabilities. In addition to searching for web application-specific vulnerabilities, the tools also look for software coding errors.” Resolving vulnerabilities is commonly referred to as remediation. Corrections to the code can be made in the application but typically a more prompt response is necessary. In these situations, the application of a custom policy for a unique web application vulnerability to provide a temporary but immediate fix (known as a virtual patch) may be necessary.\r\nWAFs are not an ultimate security solution, rather they are meant to be used in conjunction with other network perimeter security solutions such as network firewalls and intrusion prevention systems to provide a holistic defense strategy.\r\nWAFs typically follow a positive security model, a negative security model, or a combination of both as mentioned by the SANS Institute. WAFs use a combination of rule-based logic, parsing, and signatures to detect and prevent attacks such as cross-site scripting and SQL injection. The OWASP produces a list of the top ten web application security flaws. All commercial WAF offerings cover these ten flaws at a minimum. There are non-commercial options as well. As mentioned earlier, the well-known open source WAF engine called ModSecurity is one of these options. A WAF engine alone is insufficient to provide adequate protection, therefore OWASP along with Trustwave's Spiderlabs help organize and maintain a Core-Rule Set via GitHub to use with the ModSecurity WAF engine.","materialsDescription":"A Web Application Firewall or WAF provides security for online services from malicious Internet traffic. WAFs detect and filter out threats such as the OWASP Top 10, which could degrade, compromise or bring down online applications.\r\n<span style=\"font-weight: bold;\">What are Web Application Firewalls?</span>\r\nWeb application firewalls assist load balancing by examining HTTP traffic before it reaches the application server. They also protect against web application vulnerability and unauthorized transfer of data from the web server at a time when security breaches are on the rise. According to the Verizon Data Breach Investigations Report, web application attacks were the most prevalent breaches in 2017 and 2018.\r\nThe PCI Security Standards Council defines a web application firewall as “a security policy enforcement point positioned between a web application and the client endpoint.

WAFs block bad traffic outright or can challenge a visitor with a CAPTCHA test that humans can pass but a malicious bot or computer program cannot.\r\nWAFs follow rules or policies customized to specific vulnerabilities. As a result, this is how WAFs prevent DDoS attacks. Creating the rules on a traditional WAF can be complex and require expert administration. The Open Web Application Security Project maintains a list of the OWASP top web application security flaws for WAF policies to address.\r\nWAFs come in the form of hardware appliances, server-side software, or filter traffic as-a-service. WAFs can be considered as reverse proxies i.e. the opposite of a proxy server. Proxy servers protect devices from malicious applications, while WAFs protect web applications from malicious endpoints.\r\n<span style=\"font-weight: bold;\">What Are Some Web Application Firewall Benefits?</span>\r\nA web application firewall (WAF) prevents attacks that try to take advantage of the vulnerabilities in web-based applications.

Web application firewall installation must include the following four steps: secure, monitor, test and improve. This should be a continuous process to ensure application specific protection.<br />The configuration of the firewall should be determined by the business rules and guardrails by the company’s security policy.

Types of network security appliance:\r\n<span style=\"font-weight: bold;\">Active devices</span> block unwanted traffic. Examples of such devices are firewalls, anti-virus scanning devices, and content filtering devices. For instance, if you want to make sure that you do not get pointless spam and other unnecessary issues, installing an active device might be a great idea. Active devices include anti-virus scanning devices, which will automatically scan throughout the network to ensure that no virus exists within the protected network. Then, there are web filtering appliances as well as firewalls, the purpose of both of which is to ensure that only useful content and traffic flows through the network and all pointless or harmful data is filtered.\r\n<span style=\"font-weight: bold;\">Passive devices detect and report on unwanted traffic.</span> A common example is intrusion detection appliances, which are installed in order to determine whether the network has been compromised in any way. These devices usually work in the background at all times.\r\n<span style=\"font-weight: bold;\">Preventative devices</span> scan networks and identify potential security problems (such as penetration testing and vulnerability assessment appliances). These devices are usually designed to 'prevent' damage to the network by identifying problems in advance. Common examples include devices that employ penetration testing as well as those devices which carry out vulnerability assessment on networks.\r\n<span style=\"font-weight: bold;\">Unified Threat Management (UTM)</span> combines features together into one system, such as some firewalls, content filtering, web caching etc. UTM devices are designed to provide users with a one-stop solution to all of their network needs and internet security appliances. As the name clearly suggests, these devices provide the features of all of the other network devices and condense them into one. These devices are designed to provide a number of different network security options in one package, hence providing networks with a simple solution. Rather than installing four different devices, users can easily install one and be done with it. The market of UTM devices has exceeded the billion dollar mark already, which just goes to show how popular these devices have become amongst network users.\r\nOne of the most popular and accessible types of web security appliance tools is the hardware <span style=\"font-weight: bold;\">keylogger.</span> This device is placed covertly between the case and keyboard with an output for the computer case and input for the keyboard. As hardware standards have changed over time, a USB hardware keylogger provides access on many devices.\r\nThe <span style=\"font-weight: bold;\">web proxy appliance</span> is basically hardware you use to manage user web access. More to the point, it's the type of device that handles the blocking or controlling of suspicious programs. It's typically placed in between network users and the worldwide web; ergo, it's most popular application is serving as a central control hub over employee Internet use by corporations and enterprises.

It typically protects web applications from attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection, among others. A WAF is a protocol layer 7 defense (in the OSI model), and is not designed to defend against all types of attacks. This method of attack mitigation is usually part of a suite of tools which together create a holistic defense against a range of attack vectors.\r\nIn recent years, web application security has become increasingly important, especially after web application attacks ranked as the most common reason for breaches, as reported in the Verizon Data Breach Investigations Report. WAFs have become a critical component of web application security, and guard against web application vulnerabilities while providing the ability to customize the security rules for each application. As WAF is inline with traffic, some functions are conveniently implemented by a load balancer.\r\nAccording to the PCI Security Standards Council, WAFs function as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in software or hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.”\r\nBy deploying a WAF firewall in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a web firewall is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server.\r\nA WAF operates through a set of rules often called <span style=\"font-weight: bold; \">policies.</span> These policies aim to protect against vulnerabilities in the application by filtering out malicious traffic. The value of a WAF management comes in part from the speed and ease with which policy modification can be implemented, allowing for faster response to varying attack vectors; during a DDoS attack, rate limiting can be quickly implemented by modifying WAF policies.\r\nWAF solutions can be deployed in several ways—it all depends on where your applications are deployed, the services needed, how you want to manage it, and the level of architectural flexibility and performance you require. Do you want to manage it yourself, or do you want to outsource that management? Is it a better model to have a cloud WAF service, option or do you want your WAF to sit on-premises?\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">A WAF products can be implemented one of three different ways:</span></p>\r\n<ul><li><span style=\"font-weight: bold; \">A network-based WAF</span> is generally hardware-based. Since they are installed locally they minimize latency, but network-based WAFs are the most expensive option and also require the storage and maintenance of physical equipment.</li><li><span style=\"font-weight: bold; \">A host-based WAF</span> may be fully integrated into an application’s software. This solution is less expensive than a network-based WAF and offers more customizability. The downside of a host-based WAF is the consumption of local server resources, implementation complexity, and maintenance costs. These components typically require engineering time, and may be costly.</li><li><span style=\"font-weight: bold; \">Cloud-based WAFs</span> offer an affordable option that is very easy to implement; they usually offer a turnkey installation that is as simple as a change in DNS to redirect traffic. Cloud-based WAFs also have a minimal upfront cost, as users pay monthly or annually for security as a service. Cloud-based WAFs can also offer a solution that is consistently updated to protect against the newest threats without any additional work or cost on the user’s end. The drawback of a cloud-based WAF is that users hand over the responsibility to a third-party, therefore some features of the WAF may be a black box to them. </li></ul>\r\n<p class=\"align-left\">&nbsp;</p>\r\n\r\n","materialsDescription":"<p class=\"align-center\"><span style=\"color: rgb(97, 97, 97); \"><span style=\"font-weight: bold; \">What types of attack WAF prevents?</span></span></p>\r\n<p class=\"align-left\"><span style=\"color: rgb(97, 97, 97); \">WAFs can prevent many attacks, including:</span></p>\r\n<ul><li><span style=\"color: rgb(97, 97, 97); \">Cross-site Scripting (XSS) — Attackers inject client-side scripts into web pages viewed by other users.</span></li><li><span style=\"color: rgb(97, 97, 97); \">SQL injection — Malicious code is inserted or injected into an web entry field that allows attackers to compromise the application and underlying systems.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Cookie poisoning — Modification of a cookie to gain unauthorized information about the user for purposes such as identity theft.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Unvalidated input — Attackers tamper with HTTP request (including the url, headers and form fields) to bypass the site’s security mechanisms.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Layer 7 DoS — An HTTP flood attack that utilizes valid requests in typical URL data retrievals.</span></li><li><span style=\"color: rgb(97, 97, 97); \">Web scraping — Data scraping used for extracting data from websites.</span><span style=\"font-weight: bold; \"></span></li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">What are some WAFs Benefits?</span></p>\r\nWeb app firewall prevents attacks that try to take advantage of the vulnerabilities in web-based applications.

They are effective at blocking bad L3-L4 traffic at the perimeter on the lower end (L3-L4) of the Open Systems Interconnection (OSI) model. Traditional firewalls cannot detect attacks in web applications because they do not understand Hypertext Transfer Protocol (HTTP) which occurs at layer 7 of the OSI model. They also only allow the port that sends and receives requested web pages from an HTTP server to be open or closed. This is why web application firewalls are effective for preventing attacks like SQL injections, session hijacking and Cross-Site Scripting (XSS).","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAF_web_application_firewall.png"},{"id":546,"title":"WAF-web application firewall appliance","alias":"waf-web-application-firewall-appliance","description":"A web application firewall is a special type of application firewall that applies specifically to web applications. It is deployed in front of web applications and analyzes bi-directional web-based (HTTP) traffic - detecting and blocking anything malicious. The OWASP provides a broad technical definition for a WAF as “a security solution on the web application level which - from a technical point of view - does not depend on the application itself.” According to the PCI DSS Information Supplement for requirement 6.6, a WAF is defined as “a security policy enforcement point positioned between a web application and the client endpoint. This functionality can be implemented in hardware, running in an appliance device, or in a typical server running a common operating system. It may be a stand-alone device or integrated into other network components.” In other words, a WAF can be a physical appliance that prevents vulnerabilities in web applications from being exploited by outside threats. These vulnerabilities may be because the application itself is a legacy type or it was insufficiently coded by design. The WAF addresses these code shortcomings by special configurations of rule sets, also known as policies.\r\nPreviously unknown vulnerabilities can be discovered through penetration testing or via a vulnerability scanner. A web application vulnerability scanner, also known as a web application security scanner, is defined in the SAMATE NIST 500-269 as “an automated program that examines web applications for potential security vulnerabilities. In addition to searching for web application-specific vulnerabilities, the tools also look for software coding errors.” Resolving vulnerabilities is commonly referred to as remediation. Corrections to the code can be made in the application but typically a more prompt response is necessary. In these situations, the application of a custom policy for a unique web application vulnerability to provide a temporary but immediate fix (known as a virtual patch) may be necessary.\r\nWAFs are not an ultimate security solution, rather they are meant to be used in conjunction with other network perimeter security solutions such as network firewalls and intrusion prevention systems to provide a holistic defense strategy.\r\nWAFs typically follow a positive security model, a negative security model, or a combination of both as mentioned by the SANS Institute. WAFs use a combination of rule-based logic, parsing, and signatures to detect and prevent attacks such as cross-site scripting and SQL injection. The OWASP produces a list of the top ten web application security flaws. All commercial WAF offerings cover these ten flaws at a minimum. There are non-commercial options as well. As mentioned earlier, the well-known open source WAF engine called ModSecurity is one of these options. A WAF engine alone is insufficient to provide adequate protection, therefore OWASP along with Trustwave's Spiderlabs help organize and maintain a Core-Rule Set via GitHub to use with the ModSecurity WAF engine.","materialsDescription":"A Web Application Firewall or WAF provides security for online services from malicious Internet traffic. WAFs detect and filter out threats such as the OWASP Top 10, which could degrade, compromise or bring down online applications.\r\n<span style=\"font-weight: bold;\">What are Web Application Firewalls?</span>\r\nWeb application firewalls assist load balancing by examining HTTP traffic before it reaches the application server. They also protect against web application vulnerability and unauthorized transfer of data from the web server at a time when security breaches are on the rise. According to the Verizon Data Breach Investigations Report, web application attacks were the most prevalent breaches in 2017 and 2018.\r\nThe PCI Security Standards Council defines a web application firewall as “a security policy enforcement point positioned between a web application and the client endpoint.

WAFs block bad traffic outright or can challenge a visitor with a CAPTCHA test that humans can pass but a malicious bot or computer program cannot.\r\nWAFs follow rules or policies customized to specific vulnerabilities. As a result, this is how WAFs prevent DDoS attacks. Creating the rules on a traditional WAF can be complex and require expert administration. The Open Web Application Security Project maintains a list of the OWASP top web application security flaws for WAF policies to address.\r\nWAFs come in the form of hardware appliances, server-side software, or filter traffic as-a-service. WAFs can be considered as reverse proxies i.e. the opposite of a proxy server. Proxy servers protect devices from malicious applications, while WAFs protect web applications from malicious endpoints.\r\n<span style=\"font-weight: bold;\">What Are Some Web Application Firewall Benefits?</span>\r\nA web application firewall (WAF) prevents attacks that try to take advantage of the vulnerabilities in web-based applications.

Web application firewall installation must include the following four steps: secure, monitor, test and improve.
