Chapter 13. Intrusion Detection System (IDS) Sensors

Refer to the following sections for information about these topics:

• 13-1: IDS Overview Discusses the Cisco IDS components and operation. The firewall and router embedded IDS sensors are covered in detail.

• 13-2: IDS Embedded Sensor Configuration Provides a sequence of steps you can follow to configure a Cisco firewall or router as an IDS sensor.

• 13-3: Monitoring IDS Activity Presents steps you can take to verify that an IDS sensor is operating and reporting alarms correctly.

• 13-4: IDS Sensor Signature List Gives a complete list of signatures available in the firewall and router IDS sensor platforms.

Intrusion Detection Systems (IDSs) are also called Intrusion Protection Systems (IPSs). The terminology is evolving, so these two terms are used interchangeably in this chapter.
