how ccna works

how ccna works.Human-to-human connections: involving collaboration technologies such as TelePresence and WebEx. Machine-to-human connections: involving traditional and new applications. Big data analytics performed for cybersecurity within the loE domain requires a lot of engineering to process huge data setsCombined. Scalability can be a huge challenge. In addition, the wide variety of IoT applications can create problems for security operations and maintenance. People are facing these challenges today. For example, on the factory floor, embedded ProgrammableLogicControllers (PLCs) that control production systems and robots can be prime targets for malicious actors. Only by being fully aware of all potential indicators of a real attack can we analyze and respond to security incidents in depth.In this ever-changing world, the need to combine threat intelligence with big data analytics will become increasingly important.Configuring FlexibleNetFlow on CiscoIOS and CiscoIOS-XE AppliancesFlexibleNetFlow goes beyond several other flow-based technologies available today to enhance and optimize network infrastructure, reduce costs, and improve the efficiency of capacity planning and security detection. As of CiscoIOS Software Release 15.2(1)T, FlexibleNetFlow supports IPv6 and IPv6-based Network Application Recognition (NBAR). flexible NetFlow also supports IPv6 transition technologies (IPv6 within IPv4) o11.2 Network Insight Technologies 429Flexible NetFlow can track multiple applications simultaneously. For example, security monitoring, traffic analysis, and billing can be tracked separately, as well as information customized to the application.Network administrators or network security personnel can use Flexible NetFlow to create multiple caches of flows or databases of information to be tracked. NetFlow typically has only one cache, and all applications use the same cached information. Flexible NetFlow supports capturing specific security information in one flow cache and analyzing traffic in another flow cache. Each NetFlow cache then serves a different purpose. For example, multicast and security information can be tracked separately, and then the results sent to two different collectors. Figure 11-23 shows the FlexibleNetFlow model and how the 3 different monitors are used. Monitor 1 exports Flexible NetFlow data to Exporter 1, Monitor 2 exports Flexible NetFlow data to Exporter 2, and Monitor 3 exports FlexibleNetFlow data to Exporters 1 and 3.The following shows the Flexible NetFlow components.Record.
