Lesson 1- Intrusion Detection
This document discusses intrusion detection and prevention systems (IDPS). It defines the key concepts of intrusion detection, prevention, reaction, and correction. There are two main types of IDPS: network-based systems which monitor network traffic for attacks, and host-based systems which monitor activity on individual hosts. The document outlines the advantages and disadvantages of both approaches. It also describes different models of network-based IDPS including wireless and network behavior analysis systems.
