IdM systems fall under the overarching umbrellas of IT security and Data Management.\r\nWith an IAM framework in place, information technology (IT) managers can control user access to critical information within their organizations. Identity and access management software offers role-based access control, which lets system administrators regulate access to systems or networks based on the roles of individual users within the enterprise. In this context, access is the ability of an individual user to perform a specific task, such as view, create or modify a file. Roles are defined according to job competency, authority and responsibility within the enterprise.\r\nSystems used for identity and access management include single sign-on systems, multi-factor authentication and privileged access management (PAM). These technologies also provide the ability to securely store identity and profile data as well as data governance functions to ensure that only data that is necessary and relevant is shared. IAM systems can be deployed on premises, provided by a third-party vendor through a cloud-based subscription model or deployed in a hybrid cloud.\r\n<span style=\"font-weight: bold; \">Basic components of IAM.</span> On a fundamental level, IAM encompasses the following components:\r\n<ul><li>How individuals are identified in a system.</li><li>How roles are identified in a system and how they are assigned to individuals.</li><li>Adding, removing and updating individuals and their roles in a system.</li><li>Assigning levels of access to individuals or groups of individuals.</li><li>Protecting the sensitive data within the system and securing the system itself.</li></ul>\r\nAccess identity management system should consist of all the necessary controls and tools to capture and record user login information, manage the enterprise database of user identities and orchestrate the assignment and removal of access privileges. That means that systems used for IAM should provide a centralized directory service with oversight as well as visibility into all aspects of the company user base.\r\nTechnologies for identity access and management should simplify the user provisioning and account setup process. User access management software should reduce the time it takes to complete these processes with a controlled workflow that decreases errors as well as the potential for abuse while allowing automated account fulfillment. An identity and access management system should also allow administrators to instantly view and change access rights.\r\nIAM systems should be used to provide flexibility to establish groups with specific privileges for specific roles so that access rights based on employee job functions can be uniformly assigned. Identity access management software should also provide request and approval processes for modifying privileges because employees with the same title and job location may need customized, or slightly different, access.\r\n\r\n","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: bold; \">What is the difference between identity and access management?</span></h1>\r\nAfter authentication, there needs to be an access control decision. The decision is based on the information available about the user. The difference between identity management and access management is thus:\r\n<ul><li>Identity Management is about managing the attributes related to the user.</li><li>Access Management is about evaluating the attributes based on policies and making Yes/No decisions.</li></ul>\r\nThere are three types of Access Control Systems: \r\n<ul><li>Discretionary Access Control (DAC)</li><li>Mandatory Access Control (MAC)</li><li>Role-Based Access Control (RBAC)</li></ul>\r\n<h1 class=\"align-center\">What are the main benefits of identity management?</h1>\r\nIdentity access and management are useful in many ways: it ensures regulatory compliance, enables cost savings, and simplifies the lives of your customers by enhancing their experience. These are the main benefits of having an IAM solution:\r\n<ul><li><span style=\"font-weight: bold; \">Easily accessible anywhere</span></li></ul>\r\nNowadays, people need their identities all the time to use services and resources. In that sense, they require access to any platform without limits using their IDs, thus eliminating barriers for customers to enter the platform anytime, anywhere.\r\n<ul><li><span style=\"font-weight: bold; \">It encourages the connection between the different parts</span></li></ul>\r\nThe digital transformation that is taking place among more and more organizations forces the need for people, applications and devices to stay connected to each other. And, as expected, all of these processes bring with them some security threats.\r\nHowever, IAM software is a solution that guarantees correct administration with the best identity providers, such as Salesforce, Twitter and Google. Authentication and security are two of the strengths of Identity and Access Management, as well as being extendable and ready for future advances.&nbsp; \r\n<ul><li><span style=\"font-weight: bold; \">It improves productivity</span></li></ul>\r\nIdentity software automates the entry of new personnel and facilitates access to all components of the system with which the company operates. This allows reducing times in the delivery of access so that they begin to produce immediately. For this reason, business agility is also increased by using the advantages that technology makes available to meet the demands of today’s world. \r\n<ul><li><span style=\"font-weight: bold; \">It optimizes user experience</span></li></ul>\r\nRemembering so many usernames and passwords to access social networks, banks and other services on the Internet becomes a challenge for people. Thanks to user identity management system, people can get an identity that provides access to different systems. Single sign-on (SSO) allows customers and partners to access different internal and external applications with the same access method. That way the user experience will not be affected.\r\n<ul><li><span style=\"font-weight: bold; \">Secure your brand at all levels</span></li></ul>\r\nThere will be no risk of security breach, regardless of whether a connection is made from multiple identity providers. Identity management software and access management software enables strong authentication to keep your business and brand secure. Detailed verification of all identities entering the system is performed, in addition to allowing various licenses to limit access levels. At the same time, it monitors through analysis, fraud detection and alert functions that indicate a possible real risk. In short, enterprise identity management system is a reliable tool that employs technology to support digital transformation. A software that provides agility, security and satisfaction to the company’s customers.

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","alias":"siem-security-information-and-event-management"},"56":{"id":56,"title":"Router","description":"A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.\r\nA router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.\r\nThe most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an Internet service provider (ISP). More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone.\r\nThe main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address. When a router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the addresses in the routing table. Once a match is found, the packet is encapsulated in the layer-2 data link frame for the outgoing interface indicated in the table entry. A router typically does not look into the packet payload,[citation needed] but only at the layer-3 addresses to make a forwarding decision, plus optionally other information in the header for hints on, for example, quality of service (QoS). For pure IP forwarding, a router is designed to minimize the state information associated with individual packets. Once a packet is forwarded, the router does not retain any historical information about the packet.\r\nThe routing table itself can contain information derived from a variety of sources, such as a default or static routes that are configured manually, or dynamic routing protocols where the router learns routes from other routers. A default route is one that is used to route all traffic whose destination does not otherwise appear in the routing table; this is common – even necessary – in small networks, such as a home or small business where the default route simply sends all non-local traffic to the Internet service provider. The default route can be manually configured (as a static route), or learned by dynamic routing protocols, or be obtained by DHCP.\r\nA router can run more than one routing protocol at a time, particularly if it serves as an autonomous system border router between parts of a network that run different routing protocols; if it does so, then redistribution may be used (usually selectively) to share information between the different protocols running on the same router.\r\nBesides making a decision as to which interface a packet is forwarded to, which is handled primarily via the routing table, a router also has to manage congestion when packets arrive at a rate higher than the router can process. Three policies commonly used in the Internet are tail drop, random early detection (RED), and weighted random early detection (WRED). Tail drop is the simplest and most easily implemented; the router simply drops new incoming packets once the length of the queue exceeds the size of the buffers in the router. RED probabilistically drops datagrams early when the queue exceeds a pre-configured portion of the buffer, until a pre-determined max, when it becomes tail drop. WRED requires a weight on the average queue size to act upon when the traffic is about to exceed the pre-configured size, so that short bursts will not trigger random drops.\r\nAnother function a router performs is to decide which packet should be processed first when multiple queues exist. This is managed through QoS, which is critical when Voice over IP is deployed, so as not to introduce excessive latency.\r\nYet another function a router performs is called policy-based routing where special rules are constructed to override the rules derived from the routing table when a packet forwarding decision is made.\r\nRouter functions may be performed through the same internal paths that the packets travel inside the router. Some of the functions may be performed through an application-specific integrated circuit (ASIC) to avoid overhead of scheduling CPU time to process the packets. Others may have to be performed through the CPU as these packets need special attention that cannot be handled by an ASIC.","materialsDescription":" <span style=\"font-weight: bold;\">What Is a Router?</span>\r\nRouters are the nodes that make up a computer network like the internet. The router you use at home is the central node of your home network.\r\nIt functions as an information manager between the internet and all devices that go online (i.e. all devices connected to the router). Generally speaking, routers direct incoming traffic to its destination.\r\nThis also makes your router the first line of security in protecting your home network from malicious online attacks.\r\n<span style=\"font-weight: bold;\">What Does a Router Do?</span>\r\nYour router handles network traffic. For example, to view this article, data packages coding for this website have to transit from our server, through various nodes on the internet, and finally through your router to arrive on your phone or computer. On your device, your browser decodes those data packages to display the article you’re currently reading.\r\nSince a typical household has more than one device that connects to the internet, you need a router to manage the incoming network signals. In other words, your router makes sure that the data packages coding for a website you want to view on your computer aren’t sent to your phone. It does that by using your device’s MAC address.\r\nWhile your router has a unique (external) IP address to receive data packages from servers worldwide, every device on your home network also carries a unique MAC address. Simply put, when you try to access information online, your router maintains a table to keep track of which device requested information from where. Based on this table, your router distributes incoming data packages to the correct recipient.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between Modems and Routers?</span>\r\nA modem turns the proprietary network signal of your ISP (internet service provider) into a standard network signal. In theory, you can choose between multiple ISPs and some of them may use the same delivery route. Your modem knows which signals to read and translate.\r\nThe kind of modem your ISP will provide you with depends on how you’re connecting to the internet. For example, a DSL modem requires a different technology than a cable or fiber optic broadband modem. That’s because one uses the copper wiring of your telephone line, while the others use a coaxial or a fiber optic cable, respectively.\r\nThe DSL modem has to filter and read both the low frequencies that phone and voice data produce, as well as the high frequencies of internet data. Cable modems, on the other hand, have to differentiate between television and internet signals, which are transmitted on different channels, rather than different frequencies. Finally, fiber optic uses pulses of light to transmit information. The modem has to decode these signals into standard data packages.\r\nOnce the modem has turned the ISP’s network signal into data packages, the router can distribute them to the target device.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Router1.png","alias":"router"},"82":{"id":82,"title":"Unified Communications","description":"Unified communications (UC) is a framework for integrating various asynchronous and real-time communication tools. The goal of UC is to enhance business communication, collaboration and productivity. Unified communications do not represent a singular technology; rather, it describes a strategy for integrating interconnected systems of enterprise communication devices and applications that can be used in concert or successively.\r\nSome business communication tools - like Internet Protocol (IP) telephony and video conferencing - facilitate real-time communication, also called synchronous communication. Other enterprise communication tools, like email, facilitate asynchronous communication, which takes place at a person's convenience.\r\nIncreasingly, team collaboration tools have emerged to offer messaging-centric workflows and near-real-time communication. These tools also offer voice and video capabilities, API integrations and, ultimately, expound on instant messaging services by providing better UC features.\r\nThe goal of unified communications is to integrate the software that supports synchronous and asynchronous communication, so the end user has easy access to all tools from whatever device is in use.\r\nA unified communications environment is typically supported by one or more back-end systems, often referred to as UC platforms, that facilitate integration among services, as well as the front-end clients that provide access. For example, a web conferencing system would make use of an audio conferencing system - which, in turn, would be built on an underlying IP telephony platform - and a unified messaging client would allow click-to-talk (CTC), click-to-chat or click-to-video functionality.\r\nUC also supports users moving from one mode of communication to another within the same session. For example, a user may start communicating via email but then decide to escalate the interaction to real-time communication, transitioning the session to a voice call with one click and then to a video conference with another click without any disruption.\r\nUnified communications systems and their components can be deployed on premises, in a public or private cloud, or a combination of all three. Cloud-based unified communications is also called UC as a service (UCaaS). An open source project called WebRTC, for example, enables real-time communications to be embedded into web browsers.\r\nHistorically, single-vendor UC environments have demonstrated the tightest integration and compatibility. Interoperability among vendors remains an ongoing challenge in UC, but it has also been mitigated, in part, by partnerships, common protocols and open APIs.","materialsDescription":" <span style=\"font-weight: bold;\">What technology do unified communications have?</span>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Contrasting unified messaging</span></span>\r\nUnified communications are sometimes confused with unified messaging, but it is distinct. Unified communications refer to both real-time and non-real-time delivery of communications based on the preferred method and location of the recipient; unified messaging culls messages from several sources (such as e-mail, voice mail and faxes), but holds those messages only for retrieval at a later time. Unified communications allow for an individual to check and retrieve an e-mail or voice mail from any communication device at any time. It expands beyond voice mail services to data communications and video services.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Components</span></span>\r\nWith unified communications, multiple modes of business communications are integrated. Unified communications is not a single product but a collection of elements that include:\r\n<ul><li>Call control and multimodal communications</li><li>Presence</li><li>Instant messaging</li><li>Unified messaging</li><li>Speech access and personal assistant</li><li>Conferencing (audio, Web and video)</li><li>Collaboration tools</li><li>Mobility</li><li>Business process integration (BPI)</li><li>Software to enable business process integration</li></ul>\r\nPresence — knowing where intended recipients are, and if they are available, in real-time — is a key component of unified communications. Unified communications integrate all systems a user might already use, and helps those systems work together in real-time. For example, unified communications technology could allow a user to seamlessly collaborate with another person on a project, even if the two users are in separate locations. The user could quickly locate the necessary person by accessing an interactive directory, engage in a text messaging session, and then escalate the session to a voice call or even a video call.\r\nIn another example, an employee receives a call from a customer who wants answers. Unified communications enable that employee to call an expert colleague from a real-time list. This way, the employee can answer the customer faster by eliminating rounds of back-and-forth e-mails and phone-tag.\r\nThe examples in the previous paragraph primarily describe &quot;personal productivity&quot; enhancements that tend to benefit the individual user. While such benefits can be important, enterprises are finding that they can achieve even greater impact by using unified communications capabilities to transform business processes. This is achieved by integrating UC functionality directly into the business applications using development tools provided by many of the suppliers. Instead of the individual user invoking the UC functionality to, say, find an appropriate resource, the workflow or process application automatically identifies the resource at the point in the business activity where one is needed.\r\nWhen used in this manner, the concept of presence often changes. Most people associate presence with instant messaging (IM &quot;buddy lists&quot;) the status of individuals is identified. But, in many business process applications, what is important is finding someone with a certain skill. In these environments, presence identifies available skills or capabilities.\r\nThis &quot;business process&quot; approach to integrating UC functionality can result in bottom-line benefits that are an order of magnitude greater than those achievable by personal productivity methods alone.\r\n<span style=\"font-weight: bold;\">Related concepts</span>\r\nUnified communications &amp; collaboration (UCC) is the integration of various communications methods with collaboration tools such as virtual white boards, real-time audio and video conferencing, and enhanced call control capabilities. Before this fusion of communications and collaboration tools into a single platform, enterprise collaboration service vendors and enterprise communications service vendors offered distinctly different solutions. Now, collaboration service vendors also offer communications services, and communications service providers have developed collaboration tools.\r\nUnified communications &amp; collaboration as a service (UCCaaS) is cloud-based UCC platforms. Compared to premises-based UCC solutions, UCCaaS platforms offer enhanced flexibility and scalability due to the SaaS subscription model.\r\nUnified communications provisioning is the act of entering and configuring the settings for users of phone systems, instant messaging, telepresence, and other collaboration channels. Provisioners refer to this process as making moves, adds, changes, and deletes or MAC-Ds.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Unified_Communications.png","alias":"unified-communications"},"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.

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"},"204":{"id":204,"title":"Managed Detection and Response","description":" MDR, which stands for Managed Detection &amp; Response, is an all-encompassing threat detection system, which arose from the need for small/medium-sized organizations who lack resources to be able to monitor their network systems in-house.

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.

In plain words, these scanners are used to discover the weaknesses of a given system. They are utilized in the identification and detection of vulnerabilities arising from mis-configurations or flawed programming within a network-based asset such as a firewall, router, web server, application server, etc. They&nbsp; are typically available as SaaS (Software as a service); provided over the internet and delivered as a web application. \r\nMost vulnerability scanners will also attempt to log in to systems using default or other credentials in order to build a more detailed picture of the system. After building up an inventory, the vulnerability scanner checks each item in the inventory against one or more databases of known vulnerabilities to see if any items are subject to any of these vulnerabilities. The result of such scan is a systems vulnerability analysis, highlighting any that have known vulnerabilities that may need threat and vulnerability management.\r\n<span style=\"font-weight: bold;\">How vulnerability scanning works</span>. Vulnerability scanning finds systems and software that have known security vulnerabilities, but this information is only useful to IT security teams when it is used as the first part of a four-part vulnerability management process. <span style=\"font-weight: bold;\">Vulnerability management process involves:</span>\r\n<ul><li>Identification of vulnerabilities</li><li>Evaluation of the risk posed by any vulnerabilities identified</li><li>Treatment of any identified vulnerabilities</li><li>Reporting on vulnerabilities and how they have been handled</li></ul>\r\n<br /><span style=\"font-weight: bold;\">Types of vulnerability scans. </span>Not all vulnerability scans are alike, and to ensure compliance with certain regulations (such as those set by the PCI Security Standards Council) it is necessary to carry out two distinct types of vulnerability scans: an internal and an external vulnerability scan. \r\n<span style=\"font-weight: bold;\">External vulnerability scan.</span> As the name suggests, an external vulnerability scan is carried out from outside an organization's network, and its principal purpose is to detect vulnerabilities in the perimeter defenses such as open ports in the network firewall or specialized web application firewall. An external vulnerability scan can help organizations fix security issues that could enable hackers to gain access to the organization's network.\r\n<span style=\"font-weight: bold;\">Internal vulnerability scan. </span>By contrast, an internal vulnerability scan is carried out from inside an organization's perimeter defenses.

A scan may be performed by an organization’s IT department or a security service provide, possibly as a condition imposed by some authority.&nbsp; Vulnerability scans are also used by attackers looking for points of entry.\r\nA vulnerability scanner runs from the end point of the person inspecting the attack surface in question. The software compares details about the target attack surface to a database of information about known security holes in services and ports, anomalies in packet construction, and potential paths to exploitable programs or scripts. The scanner software attempts to exploit each vulnerability that is discovered.\r\nRunning a vulnerability scan can pose its own risks as it is inherently intrusive on the target machine’s running code. As a result, the scan can cause issues such as errors and reboots, reducing productivity.\r\n<h1 class=\"align-center\">How to choose the best vulnerability scanning tool?</h1>\r\nWhen researching vulnerability scanners, it's important to find out how they're rated for accuracy (the most important metric) as well as reliability, scalability and reporting. If accuracy is lacking, you'll end up running two different scanners, hoping that one picks up vulnerabilities that the other misses. This adds cost and effort to the scanning process. \r\n<span style=\"font-weight: bold;\">Software-Based Vulnerability Scanners.</span> These types of scanning products generally include configuration auditing, target profiling, penetration testing and detailed vulnerability analysis. They integrate with Windows products, such as Microsoft System Center, to provide intelligent patch management; some work with mobile device managers. They can scan not only physical network devices, servers and workstations, but extend to virtual machines, BYOD mobile devices and databases.\r\n<span style=\"font-weight: bold;\">Cloud-Based Vulnerability Scanners: </span>Continuous, On-Demand Monitoring. A newer type of vulnerability finder&nbsp; is delivered on-demand as Software as a Service (SaaS). Like software-based scanners, on-demand scanners incorporate links for downloading vendor patches and updates for identified vulnerabilities, reducing remediation effort. These services also include scanning thresholds to prevent overloading devices during the scanning process, which can cause devices to crash.\r\n<h1 class=\"align-center\">What is mobile application security scanner?</h1>\r\nMobile application security testing can help ensure there aren’t any loopholes in the software that may cause data loss. The sets of tests are meant to attack the app to identify possible threats and vulnerabilities that would allow external persons or systems to access private information stored on the mobile device. \r\nMobile application vulnerability scanner can help to ensure that applications are free from the flaws and weaknesses that hackers use to gain access to sensitive information. From backdoors, malicious code and other threats, these flaws may be present both in commercial and open source applications as well as software developed in-house.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Vulnerability_Scanner.png","alias":"vulnerability-scanner"}},"branches":"Information Technology","companySizes":"1001 to 2000 Employees","companyUrl":"http://www.extremenetworks.com/","countryCodes":[],"certifications":[],"isSeller":true,"isSupplier":false,"isVendor":true,"presenterCodeLng":"","seo":{"title":"Extreme Networks","keywords":"Ethernet, Gigabit, Extreme, Networks, metro, networks, using, grade","description":"Extreme Networks is a networking company based in San Jose, California that was founded in 1996.

Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.\r\nA router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.\r\nThe most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an Internet service provider (ISP). More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone.\r\nThe main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address. When a router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the addresses in the routing table. Once a match is found, the packet is encapsulated in the layer-2 data link frame for the outgoing interface indicated in the table entry. A router typically does not look into the packet payload,[citation needed] but only at the layer-3 addresses to make a forwarding decision, plus optionally other information in the header for hints on, for example, quality of service (QoS). For pure IP forwarding, a router is designed to minimize the state information associated with individual packets. Once a packet is forwarded, the router does not retain any historical information about the packet.\r\nThe routing table itself can contain information derived from a variety of sources, such as a default or static routes that are configured manually, or dynamic routing protocols where the router learns routes from other routers. A default route is one that is used to route all traffic whose destination does not otherwise appear in the routing table; this is common – even necessary – in small networks, such as a home or small business where the default route simply sends all non-local traffic to the Internet service provider. The default route can be manually configured (as a static route), or learned by dynamic routing protocols, or be obtained by DHCP.\r\nA router can run more than one routing protocol at a time, particularly if it serves as an autonomous system border router between parts of a network that run different routing protocols; if it does so, then redistribution may be used (usually selectively) to share information between the different protocols running on the same router.\r\nBesides making a decision as to which interface a packet is forwarded to, which is handled primarily via the routing table, a router also has to manage congestion when packets arrive at a rate higher than the router can process. Three policies commonly used in the Internet are tail drop, random early detection (RED), and weighted random early detection (WRED). Tail drop is the simplest and most easily implemented; the router simply drops new incoming packets once the length of the queue exceeds the size of the buffers in the router. RED probabilistically drops datagrams early when the queue exceeds a pre-configured portion of the buffer, until a pre-determined max, when it becomes tail drop. WRED requires a weight on the average queue size to act upon when the traffic is about to exceed the pre-configured size, so that short bursts will not trigger random drops.\r\nAnother function a router performs is to decide which packet should be processed first when multiple queues exist. This is managed through QoS, which is critical when Voice over IP is deployed, so as not to introduce excessive latency.\r\nYet another function a router performs is called policy-based routing where special rules are constructed to override the rules derived from the routing table when a packet forwarding decision is made.\r\nRouter functions may be performed through the same internal paths that the packets travel inside the router. Some of the functions may be performed through an application-specific integrated circuit (ASIC) to avoid overhead of scheduling CPU time to process the packets. Others may have to be performed through the CPU as these packets need special attention that cannot be handled by an ASIC.","materialsDescription":" <span style=\"font-weight: bold;\">What Is a Router?</span>\r\nRouters are the nodes that make up a computer network like the internet. The router you use at home is the central node of your home network.\r\nIt functions as an information manager between the internet and all devices that go online (i.e. all devices connected to the router). Generally speaking, routers direct incoming traffic to its destination.\r\nThis also makes your router the first line of security in protecting your home network from malicious online attacks.\r\n<span style=\"font-weight: bold;\">What Does a Router Do?</span>\r\nYour router handles network traffic. For example, to view this article, data packages coding for this website have to transit from our server, through various nodes on the internet, and finally through your router to arrive on your phone or computer. On your device, your browser decodes those data packages to display the article you’re currently reading.\r\nSince a typical household has more than one device that connects to the internet, you need a router to manage the incoming network signals. In other words, your router makes sure that the data packages coding for a website you want to view on your computer aren’t sent to your phone. It does that by using your device’s MAC address.\r\nWhile your router has a unique (external) IP address to receive data packages from servers worldwide, every device on your home network also carries a unique MAC address. Simply put, when you try to access information online, your router maintains a table to keep track of which device requested information from where. Based on this table, your router distributes incoming data packages to the correct recipient.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between Modems and Routers?</span>\r\nA modem turns the proprietary network signal of your ISP (internet service provider) into a standard network signal. In theory, you can choose between multiple ISPs and some of them may use the same delivery route. Your modem knows which signals to read and translate.\r\nThe kind of modem your ISP will provide you with depends on how you’re connecting to the internet. For example, a DSL modem requires a different technology than a cable or fiber optic broadband modem. That’s because one uses the copper wiring of your telephone line, while the others use a coaxial or a fiber optic cable, respectively.\r\nThe DSL modem has to filter and read both the low frequencies that phone and voice data produce, as well as the high frequencies of internet data. Cable modems, on the other hand, have to differentiate between television and internet signals, which are transmitted on different channels, rather than different frequencies. Finally, fiber optic uses pulses of light to transmit information. The modem has to decode these signals into standard data packages.\r\nOnce the modem has turned the ISP’s network signal into data packages, the router can distribute them to the target device.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Router1.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":230,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/Extreme_Networks_BlackDiamond_X8.jpg","logo":true,"scheme":false,"title":"Extreme Networks BlackDiamond X8","vendorVerified":0,"rating":"1.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":0,"alias":"extreme-networks-blackdiamond-x8","companyTitle":"Extreme Networks","companyTypes":["vendor"],"companyId":2783,"companyAlias":"extreme-networks","description":"Cloud-Scale Data Center Switch\r\nMeets HPC, IXP, and data center demands\r\nHigh-density wire-speed 10GbE, 40GbE, and 100GbE connectivity\r\nUnmatched performance with 20.48Tbs capacity\r\n\r\n&nbsp; &nbsp;&nbsp;\r\nMeets HPC, IXP, and data center demands\r\nHigh-density wire-speed 10GbE, 40GbE, and 100GbE connectivity\r\nUnmatched performance with 20.48Tbs capacity\r\nClick to talk to a network expert\r\n\r\nData centers today demand highly virtualized, converged, and scalable infrastructure.
