Intrusion Detection

The Cisco's IOS Firewall's Intrusion Detection system is an add-on module to the IOS Firewall Feature Set. It has 59 of the most common attack signatures to detect intrusion. When IDS detects suspicious activity, it logs the event and can either shut down the port or send an alarm before network security is compromised. Cisco Firewall IDS is supported on 2600, 3600, 7100, and 7200 series routers.
