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. Because of the data center hosting, you’re getting the added benefit of at least some disaster recovery. Lastly, the vendor manages these issues as part of their core competencies—let them.</li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Integration and scalability.</span> Most SaaS apps are designed to support some amount of customization for the way you do business. SaaS vendors create APIs to allow connections not only to internal applications like ERPs or CRMs but also to other SaaS providers. One of the terrific aspects of integration is that orders written in the field can be automatically sent to the ERP. Now a salesperson in the field can check inventory through the catalog, write the order in front of the customer for approval, send it and receive confirmation, all in minutes. And as you scale with a SaaS vendor, there’s no need to invest in server capacity and software licenses. </li></ul>\r\n\r\n<ul><li><span style=\"font-weight: bold;\">Work anywhere</span>. Since the software is hosted in the cloud and accessible over the internet, users can access it via mobile devices wherever they are connected. This includes checking customer order histories prior to a sales call, as well as having access to real time data and real time order taking with the customer.</li></ul>\r\n<p class=\"align-left\">&nbsp;</p>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/SaaS__1_.png","alias":"saas-software-as-a-service"},"174":{"id":174,"title":"​System and Network Management Software","description":"System and network management software is used to manage all the computing resources for the end-user, small business, workgroup, or enterprise, including systems, applications, and the network infrastructure.

First, make sure that the commercial tool meets the bulk of your requirements. (The product probably won’t meet all your needs, which is why you also need in-house tools.) Second, how easily can you roll out the product, and how much training will your team need before you can capitalize on your investment? Analysts recommend that if you can evaluate demonstration software first, do so. If you can wait to purchase management software until you’ve tested it in your lab, ensured that it will integrate with your existing in-house or third-party tools, and successfully rolled it out to your production environment.","materialsDescription":" <span style=\"font-weight: bold;\">What is the difference between a network operating system and a network-management software?</span>\r\nDifference between network operating system and network management software:\r\n<span style=\"font-weight: bold;\">Network operating system</span>\r\n<ul><li>The network operating system is used to controls computer systems and network devices and permits them to communicate with one another.</li><li>The network operating system performs the same functions for the network as operating system software does for a computer...</li></ul>\r\n<span style=\"font-weight: bold;\">Network management software</span>\r\n<ul><li>Network management software is used to monitor, discover, provision and maintain computer networks.</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/_System_and_Network_Management_Software.png","alias":"system-and-network-management-software"},"197":{"id":197,"title":"WAN optimization","description":" WAN optimization is a collection of techniques for increasing data transfer efficiencies across wide-area networks (WANs). In 2008, the WAN optimization market was estimated to be $1 billion, and was to grow to $4.4 billion by 2014 according to Gartner, a technology research firm. In 2015 Gartner estimated the WAN optimization market to be a $1.1 billion market.\r\nThe most common measures of TCP data-transfer efficiencies (i.e., optimization) are throughput, bandwidth requirements, latency, protocol optimization, and congestion, as manifested in dropped packets. In addition, the WAN itself can be classified with regards to the distance between endpoints and the amounts of data transferred. Two common business WAN topologies are Branch to Headquarters and Data Center to Data Center (DC2DC). In general, &quot;Branch&quot; WAN links are closer, use less bandwidth, support more simultaneous connections, support smaller connections and more short-lived connections, and handle a greater variety of protocols. They are used for business applications such as email, content management systems, database application, and Web delivery. In comparison, &quot;DC2DC&quot; WAN links tend to require more bandwidth, are more distant, and involve fewer connections, but those connections are bigger (100 Mbit/s to 1 Gbit/s flows) and of longer duration. Traffic on a &quot;DC2DC&quot; WAN may include replication, back up, data migration, virtualization, and other Business Continuity/Disaster Recovery (BC/DR) flows.\r\nWAN optimization has been the subject of extensive academic research almost since the advent of the WAN. In the early 2000s, research in both the private and public sectors turned to improving the end-to-end throughput of TCP, and the target of the first proprietary WAN optimization solutions was the Branch WAN. In recent years, however, the rapid growth of digital data, and the concomitant needs to store and protect it, has presented a need for DC2DC WAN optimization. For example, such optimizations can be performed to increase overall network capacity utilization, meet inter-datacenter transfer deadlines, or minimize average completion times of data transfers. As another example, private inter-datacenter WANs can benefit optimizations for fast and efficient geo-replication of data and content, such as newly computed machine learning models or multimedia content.\r\nComponent techniques of Branch WAN Optimization include deduplication, wide area file services (WAFS), SMB proxy, HTTPS Proxy, media multicasting, web caching, and bandwidth management. Requirements for DC2DC WAN Optimization also center around deduplication and TCP acceleration, however these must occur in the context of multi-gigabit data transfer rates.","materialsDescription":" <span style=\"font-weight: bold;\">What Is WAN Optimization?</span>\r\nWAN optimization involves prioritizing specific parts of the network to receive more bandwidth. For example, you might want to allocate more throughput and bandwidth to the parts of the network involved in a critical data-processing task, to make sure it’s completed quickly. Many WAN improvements can be accomplished with either physical or logical changes to your network.\r\n<span style=\"font-weight: bold;\">Why Is WAN Optimization Important?</span>\r\nBusinesses are increasingly facing pressures on their WAN setups due to increased use of cloud computing, applications, and other network-wide technologies such as web portals. The associated increase in traffic across the WAN makes WAN optimization even more important, as network slowdowns can become a major issue if you don’t proactively manage this complexity and volume.\r\nNumerous different business processes are affected by a slow network. Even simple actions, like employees accessing files, can become unacceptably slow. If the network is dragging, it might take their business-wide file manager a while to load, and then even longer to open the file. Even though it seems like a small, two-minute task, these problems quickly add up.\r\nMeanwhile, admins may have trouble effectively managing and monitoring their network — and ensuring network security — if they’re fighting against inefficient, high-latency network infrastructure. WAN optimization can potentially allow admins — and their software tools — to more effectively protect all devices and end-users.\r\nWAN optimization also supports remote and mobile workers. When someone works remotely, they’re expanding the WAN and requiring business data to travel further. Without WAN optimization, their connection could be slow. Even simple business processes such as email can become inconvenient to use. If the network is optimized correctly, all employees will be able to access network portals and business information, even if they’re connecting remotely.\r\nFurthermore, even applications not directly affected by optimization processes can benefit when bandwidth is freed up in relation to other parts of the network. All these benefits increase business efficiency and promote cost savings as a result.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/WAN_optimization1.png","alias":"wan-optimization"},"475":{"id":475,"title":"Network Management - Hardware","description":" Your business is much more than just a machine that dispenses products or services in exchange for money. It’s akin to a living and breathing thing. Just as with the human body, in business, all the parts are interconnected and work together to move things forward.\r\nIf a company’s management is the brain, then its employees are the muscles. Muscles don’t work without the oxygen carried to them by the blood. Blood doesn’t pump through the body without the heart and circulatory system.\r\nData moves through your network like blood through veins, delivering vital information to employees who need it to do their jobs. In a business sense, the digital network is the heart and circulatory system. Without a properly functioning network, the entire business collapses. That’s why keeping networks healthy is vitally important. Just as keeping the heart healthy is critical to living a healthy life, a healthy network is a key to a thriving business. It starts with network management.\r\nNetwork management is hardware with a broad range of functions including activities, methods, procedures and the use of tools to administrate, operate, and reliably maintain computer network systems.\r\nStrictly speaking, network Management does not include terminal equipment (PCs, workstations, printers, etc.). Rather, it concerns the reliability, efficiency and capacity/capabilities of data transfer channels.","materialsDescription":" <span style=\"font-weight: bold;\">What Is Network Management?</span>\r\nNetwork management refers to the processes, tools, and applications used to administer, operate and maintain network infrastructure. Performance management and fault analysis also fall into the category of network management. To put it simply, network management is the process of keeping your network healthy, which keeps your business healthy.\r\n<span style=\"font-weight: bold;\">What Are the Components of Network Management?</span>\r\nThe definition of network management is often broad, as network management involves several different components. Here are some of the terms you’ll often hear when network management or network management software is talked about:\r\n<ul><li>Network administration</li><li>Network maintenance</li><li>Network operation</li><li>Network provisioning</li><li>Network security</li></ul>\r\n<span style=\"font-weight: bold;\">Why Is Network Management so Important When It Comes to Network Infrastructure?</span>\r\nThe whole point of network management is to keep the network infrastructure running smoothly and efficiently. Network management helps you:\r\n<ul><li><span style=\"font-style: italic;\">Avoid costly network disruptions.</span> Network downtime can be very costly. In fact, industry research shows the cost can be up to $5,600 per minute or more than $300K per hour. Network disruptions take more than just a financial toll. They also have a negative impact on customer relationships. Slow and unresponsive corporate networks make it harder for employees to serve customers. And customers who feel underserved could be quick to leave.</li><li><span style=\"font-style: italic;\">Improve IT productivity.</span> By monitoring every aspect of the network, an effective network management system does many jobs at once. This frees up IT staff to focus on other things.</li><li><span style=\"font-style: italic;\">Improve network security.</span> With a focus on network management, it’s easy to identify and respond to threats before they propagate and impact end-users. Network management also aims to ensure regulatory and compliance requirements are met.</li><li><span style=\"font-style: italic;\">Gain a holistic view of network performance.</span> Network management gives you a complete view of how your network is performing. It enables you to identify issues and fix them quickly.</li></ul>\r\n<span style=\"font-weight: bold;\">What Are the Challenges of Maintaining Effective Network Management and Network Infrastructure?</span>\r\nNetwork infrastructures can be complex. Because of that complexity, maintaining effective network management is difficult. Advances in technology and the cloud have increased user expectations for faster network speeds and network availability. On top of that, security threats are becoming ever more advanced, varied and numerous. And if you have a large network, it incorporates several devices, systems, and tools that all need to work together seamlessly. As your network scales and your company grows, new potential points of failure are introduced. Increased costs also come into play.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Network_Management_Hardware__1_.png","alias":"network-management-hardware"},"485":{"id":485,"title":"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","alias":"web-security"},"536":{"id":536,"title":"WAN optimization - appliance","description":" WAN optimization appliance is a collection of techniques for increasing data-transfer efficiencies across wide-area networks (WANs). In 2008, the WAN optimization market was estimated to be $1 billion and was to grow to $4.4 billion by 2014 according to Gartner, a technology research firm. In 2015 Gartner estimated the WAN optimization market to be a $1.1 billion market.\r\nThe most common measures of TCP data-transfer efficiencies (i.e., optimization) are throughput, bandwidth requirements, latency, protocol optimization, and congestion, as manifested in dropped packets. In addition, the WAN itself can be classified with regards to the distance between endpoints and the amounts of data transferred. Two common business WAN topologies are Branch to Headquarters and Data Center to Data Center (DC2DC). In general, &quot;Branch&quot; WAN links are closer, use less bandwidth, support more simultaneous connections, support smaller connections and more short-lived connections, and handle a greater variety of protocols. They are used for business applications such as email, content management systems, database application, and Web delivery. In comparison, &quot;DC2DC&quot; WAN links tend to require more bandwidth, are more distant and involve fewer connections, but those connections are bigger (100 Mbit/s to 1 Gbit/s flows) and of longer duration. Traffic on a &quot;DC2DC&quot; WAN may include replication, back up, data migration, virtualization, and other Business Continuity/Disaster Recovery (BC/DR) flow.\r\nWAN optimization has been the subject of extensive academic research almost since the advent of the WAN. In the early 2000s, research in both the private and public sectors turned to improve the end-to-end throughput of TCP, and the target of the first proprietary WAN optimization solutions was the Branch WAN. In recent years, however, the rapid growth of digital data, and the concomitant needs to store and protect it, has presented a need for DC2DC WAN optimization. For example, such optimizations can be performed to increase overall network capacity utilization, meet inter-datacenter transfer deadlines, or minimize average completion times of data transfers. As another example, private inter-datacenter WANs can benefit optimizations for fast and efficient geo-replication of data and content, such as newly computed machine learning models or multimedia content.\r\nComponent techniques of Branch WAN Optimization include deduplication, wide-area file services (WAFS), SMB proxy, HTTPS Proxy, media multicasting, web caching, and bandwidth management. Requirements for DC2DC WAN Optimization also center around deduplication and TCP acceleration, however, these must occur in the context of multi-gigabit data transfer rates. ","materialsDescription":" <span style=\"font-weight: bold;\">What techniques does WAN optimization have?</span>\r\n<ul><li><span style=\"font-weight: bold;\">Deduplication</span> – Eliminates the transfer of redundant data across the WAN by sending references instead of the actual data. By working at the byte level, benefits are achieved across IP applications.</li><li><span style=\"font-weight: bold;\">Compression</span> – Relies on data patterns that can be represented more efficiently. Essentially compression techniques similar to ZIP, RAR, ARJ, etc. are applied on-the-fly to data passing through hardware (or virtual machine) based WAN acceleration appliances.</li><li><span style=\"font-weight: bold;\">Latency optimization</span> – Can include TCP refinements such as window-size scaling, selective acknowledgments, Layer 3 congestion control algorithms, and even co-location strategies in which the application is placed in near proximity to the endpoint to reduce latency. In some implementations, the local WAN optimizer will answer the requests of the client locally instead of forwarding the request to the remote server in order to leverage write-behind and read-ahead mechanisms to reduce WAN latency.</li><li><span style=\"font-weight: bold;\">Caching/proxy</span> – Staging data in local caches; Relies on human behavior, accessing the same data over and over.</li><li><span style=\"font-weight: bold;\">Forward error correction</span> – Mitigates packet loss by adding another loss-recovery packet for every “N” packets that are sent, and this would reduce the need for retransmissions in error-prone and congested WAN links.</li><li><span style=\"font-weight: bold;\">Protocol spoofing</span> – Bundles multiple requests from chatty applications into one. May also include stream-lining protocols such as CIFS.</li><li><span style=\"font-weight: bold;\">Traffic shaping</span> – Controls data flow for specific applications. Giving flexibility to network operators/network admins to decide which applications take precedence over the WAN. A common use case of traffic shaping would be to prevent one protocol or application from hogging or flooding a link over other protocols deemed more important by the business/administrator. Some WAN acceleration devices are able to traffic shape with granularity far beyond traditional network devices. Such as shaping traffic on a per-user AND per application basis simultaneously.</li><li><span style=\"font-weight: bold;\">Equalizing</span> – Makes assumptions on what needs immediate priority based on data usage. Usage examples for equalizing may include wide open unregulated Internet connections and clogged VPN tunnels.</li><li><span style=\"font-weight: bold;\">Connection limits</span> – Prevents access gridlock in and to denial of service or to peer. Best suited for wide-open Internet access links, can also be used links.</li><li><span style=\"font-weight: bold;\">Simple rate limits</span> – Prevents one user from getting more than a fixed amount of data. Best suited as a stop-gap first effort for remediating a congested Internet connection or WAN link.</li></ul>","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_WAN_optimization_appliance.png","alias":"wan-optimization-appliance"},"540":{"id":540,"title":"Security Hardware","description":"Hardware security as a discipline originated out of cryptographic engineering and involves hardware design, access control, secure multi-party computation, secure key storage, ensuring code authenticity and measures to ensure that the supply chain that built the product is secure, among other things.\r\nA hardware security module (HSM) is a physical computing device that safeguards and manages digital keys for strong authentication and provides cryptoprocessing. These modules traditionally come in the form of a plug-in card or an external device that attaches directly to a computer or network server.\r\nSome providers in this discipline consider that the key difference between hardware security and software security is that hardware security is implemented using &quot;non-Turing-machine&quot; logic (raw combinatorial logic or simple state machines). One approach, referred to as &quot;hardsec&quot;, uses FPGAs to implement non-Turing-machine security controls as a way of combining the security of hardware with the flexibility of software.\r\nHardware backdoors are backdoors in hardware. Conceptionally related, a hardware Trojan (HT) is a malicious modification of an electronic system, particularly in the context of an integrated circuit.\r\nA physical unclonable function (PUF) is a physical entity that is embodied in a physical structure and is easy to evaluate but hard to predict. Further, an individual PUF device must be easy to make but practically impossible to duplicate, even given the exact manufacturing process that produced it. In this respect, it is the hardware analog of a one-way function. The name &quot;physically unclonable function&quot; might be a little misleading as some PUFs are clonable, and most PUFs are noisy and therefore do not achieve the requirements for a function.

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 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.

The need to “broker” packet before it is sent to tools comes from 2 major driving forces.&nbsp; First, the throughput of tools is limited, second, every tool requires a different subset of traffic to maximize performance.\r\nPacket broker is designed to deliver only the traffic of interest required by any specific tool. NPBs achieve this by using a variety of filtering options that will be explained in detail in the next blog in this series. NPBs act as the man-in-the-middle between TAP/SPAN ports and the tool itself and should be designed with 4 different deployment scenarios in mind.\r\n<span style=\"font-weight: bold; \">Broker traffic from a single TAP port to a single tool.</span> In this application the most important function of the NPB is its filtering capability.&nbsp; Most tools currently deployed handle up to 10Gbps of traffic at any given time. If the incoming TAP traffic is 40Gbps, the traffic needs to be filtered by a factor of 4.&nbsp; The NPB needs to ensure the traffic is filtered adequately to meet this limitation while providing every packet the tool needs to do its job.\r\n<span style=\"font-weight: bold; \">Broker traffic from multiple TAP ports to a single tool.</span> This application builds on the previous, but now the NPB needs to support aggregation.&nbsp; Aggregation allows the user to setup single filters that will be applied to all incoming traffic streams, reducing the setup time/complexity of the device. Aggregation also ensures the tool receives traffic from multiple streams.\r\n<span style=\"font-weight: bold; \">Broker traffic from a single TAP port to multiple tools.</span> This application builds on the first, however, the NPB now needs to be able to replicate and/or load balance traffic. The traffic needs to be replicated/mirrored/copied to ensure each tool has access to any necessary packets.&nbsp; To properly handle this application, the NPB must also support egress filtering, to allow unique filters criteria for each different tool. If multiple tools require the same filtered traffic, the NPB must also support load balancing and options on how to load balance.&nbsp; \r\n<span style=\"font-weight: bold; \">Broker Traffic from multiple TAP ports to multiple tools.</span> The final application builds on the previous three and uses filtering, aggregation and load balancing to guarantee each tool operates at its maximum efficiency.\r\nThe current crop of NPBs plays a critical role in enabling businesses to perform several functions, such as moving to a virtual network, upgrading the network, and cost-effectively adding more advanced tools.

A good analogy to consider is the evolution of application delivery controllers (ADCs). They started as simple load balancers and then added advanced load-balancing capabilities to become ADCs. After several years, security and cloud capabilities were introduced, and the product category shifted to advanced ADCs.

It does as its title explains: it secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.\r\nNetwork security starts with authentication, commonly with a username and a password. Since this requires just one detail authenticating the user name — i.e., the password—this is sometimes termed one-factor authentication. With two-factor authentication, something the user 'has' is also used (e.g., a security token or 'dongle', an ATM card, or a mobile phone); and with three-factor authentication, something the user 'is' is also used (e.g., a fingerprint or retinal scan).\r\nOnce authenticated, a firewall enforces access policies such as what services are allowed to be accessed by the network users. Though effective to prevent unauthorized access, this component may fail to check potentially harmful content such as computer worms or Trojans being transmitted over the network. Anti-virus software or an intrusion prevention system (IPS) help detect and inhibit the action of such malware. An anomaly-based intrusion detection system may also monitor the network like wireshark traffic and may be logged for audit purposes and for later high-level analysis. Newer systems combining unsupervised machine learning with full network traffic analysis can detect active network attackers from malicious insiders or targeted external attackers that have compromised a user machine or account.\r\nCommunication between two hosts using a network may be encrypted to maintain privacy.\r\nHoneypots, essentially decoy network-accessible resources, may be deployed in a network as surveillance and early-warning tools, as the honeypots are not normally accessed for legitimate purposes. Techniques used by the attackers that attempt to compromise these decoy resources are studied during and after an attack to keep an eye on new exploitation techniques. Such analysis may be used to further tighten security of the actual network being protected by the honeypot. A honeypot can also direct an attacker's attention away from legitimate servers. A honeypot encourages attackers to spend their time and energy on the decoy server while distracting their attention from the data on the real server. Similar to a honeypot, a honeynet is a network set up with intentional vulnerabilities. Its purpose is also to invite attacks so that the attacker's methods can be studied and that information can be used to increase network security. A honeynet typically contains one or more honeypots.","materialsDescription":" <span style=\"font-weight: bold;\">What is Network Security?</span>\r\nNetwork security is any action an organization takes to prevent malicious use or accidental damage to the network’s private data, its users, or their devices.

They may be able to damage users’ devices or manipulate systems to gain physical access to facilities. This leaves the organization’s property and members at risk of harm.\r\nCompetent network security procedures keep data secure and block vulnerable systems from outside interference.

The need to “broker” packet before it is sent to tools comes from 2 major driving forces.&nbsp; First, the throughput of tools is limited, second, every tool requires a different subset of traffic to maximize performance.\r\nPacket broker is designed to deliver only the traffic of interest required by any specific tool. NPBs achieve this by using a variety of filtering options that will be explained in detail in the next blog in this series. NPBs act as the man-in-the-middle between TAP/SPAN ports and the tool itself and should be designed with 4 different deployment scenarios in mind.\r\n<span style=\"font-weight: bold; \">Broker traffic from a single TAP port to a single tool.</span> In this application the most important function of the NPB is its filtering capability.&nbsp; Most tools currently deployed handle up to 10Gbps of traffic at any given time. If the incoming TAP traffic is 40Gbps, the traffic needs to be filtered by a factor of 4.&nbsp; The NPB needs to ensure the traffic is filtered adequately to meet this limitation while providing every packet the tool needs to do its job.\r\n<span style=\"font-weight: bold; \">Broker traffic from multiple TAP ports to a single tool.</span> This application builds on the previous, but now the NPB needs to support aggregation.&nbsp; Aggregation allows the user to setup single filters that will be applied to all incoming traffic streams, reducing the setup time/complexity of the device. Aggregation also ensures the tool receives traffic from multiple streams.\r\n<span style=\"font-weight: bold; \">Broker traffic from a single TAP port to multiple tools.</span> This application builds on the first, however, the NPB now needs to be able to replicate and/or load balance traffic. The traffic needs to be replicated/mirrored/copied to ensure each tool has access to any necessary packets.&nbsp; To properly handle this application, the NPB must also support egress filtering, to allow unique filters criteria for each different tool. If multiple tools require the same filtered traffic, the NPB must also support load balancing and options on how to load balance.&nbsp; \r\n<span style=\"font-weight: bold; \">Broker Traffic from multiple TAP ports to multiple tools.</span> The final application builds on the previous three and uses filtering, aggregation and load balancing to guarantee each tool operates at its maximum efficiency.\r\nThe current crop of NPBs plays a critical role in enabling businesses to perform several functions, such as moving to a virtual network, upgrading the network, and cost-effectively adding more advanced tools. However, infrastructure evolution continues to march on, and now it’s time for <span style=\"font-weight: bold;\">next generation network packet broker</span>.\r\n<span style=\"font-weight: bold;\">Next-generation NPBs</span> are designed to meet the needs of digital businesses. A good analogy to consider is the evolution of application delivery controllers (ADCs). They started as simple load balancers and then added advanced load-balancing capabilities to become ADCs. After several years, security and cloud capabilities were introduced, and the product category shifted to advanced ADCs. The same trend is happening with NPBs as they evolve to next-generation NPBs.","materialsDescription":"<h1 class=\"align-center\"> Network Packet Brokers - How can they help you? </h1>\r\nAs your network continues to grow physically and virtually and speeds increase up 100 Gig it has become increasingly difficult to ensure that all your security and monitoring tools see and receive the real-time traffic that they need to analyze.

Hackers, disgruntled employees, or poor security practices within the organization can leave private data exposed, including trade secrets and customers’ private details.\r\nLosing confidential research, for example, can potentially cost an organization millions of dollars by taking away competitive advantages it paid to gain. While hackers stealing customers’ details and selling them to be used in fraud, it creates negative publicity and public mistrust of the organization.\r\nThe majority of common attacks against networks are designed to gain access to information, by spying on the communications and data of users, rather than to damage the network itself.\r\nBut attackers can do more than steal data. They may be able to damage users’ devices or manipulate systems to gain physical access to facilities. This leaves the organization’s property and members at risk of harm.\r\nCompetent network security procedures keep data secure and block vulnerable systems from outside interference. This allows the network’s users to remain safe and focus on achieving the organization’s goals.\r\n<span style=\"font-weight: bold;\">Why Do I Need Formal Education to Run a Computer Network?</span>\r\nEven the initial setup of security systems can be difficult for those unfamiliar with the field. A comprehensive security system is made of many pieces, each of which needs specialized knowledge.\r\nBeyond setup, each aspect of security is constantly evolving. New technology creates new opportunities for accidental security leaks, while hackers take advantage of holes in security to do damage as soon as they find them. Whoever is in charge of the network’s security needs to be able to understand the technical news and changes as they happen, so they can implement safety strategies right away.\r\nProperly securing your network using the latest information on vulnerabilities helps minimize the risk that attacks will succeed. Security Week reported that 44% of breaches in 2014 came from exploits that were 2-4 years old.\r\nUnfortunately, many of the technical aspects of network security are beyond those who make hiring decisions. So, the best way an organization can be sure that their network security personnel are able to properly manage the threats is to hire staff with the appropriate qualifications.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Network_security.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":5198,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/niagara_networks_logo.png","logo":true,"scheme":false,"title":"Niagara Network Packet Brokers","vendorVerified":0,"rating":"0.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"niagara-network-packet-brokers","companyTitle":"Niagara Networks","companyTypes":["supplier","vendor"],"companyId":6002,"companyAlias":"niagara-networks","description":"<span style=\"font-weight: bold;\">What is a Network Packet Broker?</span>\r\nA Network Packet Broker (NPB) is an active device that directs selected raw data packets from network interfaces (typically via SPAN or tap points) to specific network service and monitoring devices, and performance management and security applications.\r\n<span style=\"font-weight: bold;\">What Exactly Does a Network Packet Broker Do?</span>\r\nNiagara’s NPB solutions perform a range of crucial functionalities for all types of networks, even those with extremely complex architectures and that is resource-intensive including:\r\n<ul><li><span style=\"font-style: italic;\">Total Network Visibility</span> - Identifying known, suspicious, and unknown traffic passing through the network.</li><li><span style=\"font-style: italic;\">Network robustness</span> - Ensuring data loss prevention and advanced filtering, as well as high availability, stripping, and other special-purpose packet capabilities.</li><li><span style=\"font-style: italic;\">Network management</span> - Not just knowing how to monitor network traffic, but also knowing what to do with each type of traffic: where to pass known (authorized) data types, and how to handle suspicious and unknown traffic.</li></ul>\r\n<span style=\"font-weight: bold;\">Why You Need a Network Packet Broker?</span>\r\nIn their role as data analyzers, Niagara’s Packet Brokers can also handle the deduplication of redundant (duplicate) packets before they reach analysis or security tools within the network, that are passed along by multiple taps forwarding their data traffic.

The need to “broker” packet before it is sent to tools comes from 2 major driving forces.&nbsp; First, the throughput of tools is limited, second, every tool requires a different subset of traffic to maximize performance.\r\nPacket broker is designed to deliver only the traffic of interest required by any specific tool. NPBs achieve this by using a variety of filtering options that will be explained in detail in the next blog in this series. NPBs act as the man-in-the-middle between TAP/SPAN ports and the tool itself and should be designed with 4 different deployment scenarios in mind.\r\n<span style=\"font-weight: bold; \">Broker traffic from a single TAP port to a single tool.</span> In this application the most important function of the NPB is its filtering capability.&nbsp; Most tools currently deployed handle up to 10Gbps of traffic at any given time. If the incoming TAP traffic is 40Gbps, the traffic needs to be filtered by a factor of 4.&nbsp; The NPB needs to ensure the traffic is filtered adequately to meet this limitation while providing every packet the tool needs to do its job.\r\n<span style=\"font-weight: bold; \">Broker traffic from multiple TAP ports to a single tool.</span> This application builds on the previous, but now the NPB needs to support aggregation.&nbsp; Aggregation allows the user to setup single filters that will be applied to all incoming traffic streams, reducing the setup time/complexity of the device. Aggregation also ensures the tool receives traffic from multiple streams.\r\n<span style=\"font-weight: bold; \">Broker traffic from a single TAP port to multiple tools.</span> This application builds on the first, however, the NPB now needs to be able to replicate and/or load balance traffic. The traffic needs to be replicated/mirrored/copied to ensure each tool has access to any necessary packets.&nbsp; To properly handle this application, the NPB must also support egress filtering, to allow unique filters criteria for each different tool. If multiple tools require the same filtered traffic, the NPB must also support load balancing and options on how to load balance.&nbsp; \r\n<span style=\"font-weight: bold; \">Broker Traffic from multiple TAP ports to multiple tools.</span> The final application builds on the previous three and uses filtering, aggregation and load balancing to guarantee each tool operates at its maximum efficiency.\r\nThe current crop of NPBs plays a critical role in enabling businesses to perform several functions, such as moving to a virtual network, upgrading the network, and cost-effectively adding more advanced tools. However, infrastructure evolution continues to march on, and now it’s time for <span style=\"font-weight: bold;\">next generation network packet broker</span>.\r\n<span style=\"font-weight: bold;\">Next-generation NPBs</span> are designed to meet the needs of digital businesses. A good analogy to consider is the evolution of application delivery controllers (ADCs). They started as simple load balancers and then added advanced load-balancing capabilities to become ADCs. After several years, security and cloud capabilities were introduced, and the product category shifted to advanced ADCs. The same trend is happening with NPBs as they evolve to next-generation NPBs.","materialsDescription":"<h1 class=\"align-center\"> Network Packet Brokers - How can they help you? </h1>\r\nAs your network continues to grow physically and virtually and speeds increase up 100 Gig it has become increasingly difficult to ensure that all your security and monitoring tools see and receive the real-time traffic that they need to analyze. These tools need to know exactly what is happening on the network, and are only as good as the data they receive.\r\nThe challenge is to ensure each tool see’s the traffic that it needs to.&nbsp; Using a combination of Taps, Bypass Switches and packet brokers we can set up a visibility architecture that sits between the IT infrastructure and the tools which gives you access to all the traffic traversing the virtual and physical links.\r\n<p class=\"align-center\"><span style=\"font-weight: bold;\">NPB USES</span></p>\r\n<ul><li>Data from one network link, to one tool</li><li>Data from one network link, to multiple tools – Regeneration</li><li>Data from multiple network links, to one tool - Aggregation</li><li>Data from multiple network links, to multiple tools</li><li>Load balance traffic among all your tools</li></ul>\r\n<p class=\"align-center\"><span style=\"font-weight: bold;\">HOW NPB's BENEFIT YOU</span></p>\r\n<p class=\"align-left\">Ultimately, NPBs make monitoring and security tools more effective, by giving them access to a range of data from across the entire network.
