Chapter Description

Cisco Secure IDS is a network-based intrusion detection system that uses a signature database to trigger intrusion alarms. The major components are a sensor platform and a director platform. The sensor platform monitors the network and the director platform provides a single GUI management interface for the end user. This chapter describes the available plaforms and explains how they interact.

This sample chapter is excerpted from Cisco Secure Intrusion Detection Systems.
