ExplanationThe Firepower System uses network discovery and identity policies to collect host, application, and user data for traffic on your network. You can use certain types of discovery and identity data to build a comprehensive map of your network assets, perform forensic analysis, behavioral profiling, access control, and mitigate and respond to the vulnerabilities and exploits to which your organization is susceptible.The Cisco Advanced Malware Protection (AMP) solution enables you to detect and block malware, continuously analyze for malware, and get retrospective alerts. AMP for Networks delivers network-based advanced malware protection that goes beyond point-in-time detection to protect your organization across the entire attack continuum - before, during, and after an attack. Designed for Cisco Firepower network threat appliances, AMP for Networks detects, blocks, tracks, and contains malware threats across multiple threat vectors within a single system. It also provides the visibility and control necessary to protect your organization against highly sophisticated, targeted, zero-day, and persistent advanced malware threats.

NetFlow Secure Event Logging (NSEL) is a security logging mechanism that is built on NetFlow Version 9 technology. It provides a stateful, IP flow tracking method that exports only those records that indicate significant events in a flow, such as flow-create, flow-teardown, and flow-denied. NSEL events are triggered by the event that caused the state change in the flow. This reduces the amount of data that is exported and provides more relevant information for security analysis. NSEL also supports periodic flow-update events, which provide byte counters over the duration of the flow. These events are usually time-driven, but may also be triggered by state changes in the flow. NSEL uses templates to describe the format of the data records that are exported through NetFlow. Each event has several record formats or templates associated with it. NSEL delivers templates and data records to configured NSEL collectors through NetFlow over UDP only. NSEL also allows filtering of NSEL events based on the traffic and event type through Modular Policy Framework, and then sends records to different collectors. The supported event types are flow-create, flow-denied, flow-teardown, flow-update, and all. References := Some possible references are:
