SND v Cisco IOS IPS Signature Features Cisco IOS IPS Signature Feature Description Enables the creation of string patterns using regular expressions Enables the sensor to take an action when the signature is triggered Enables the sensor to aggregate alarms; does this to limit the number of times an alarm is sent when the signature is triggered Enables a signature to be tuned to perform optimally in a network Regular expression string pattern matching Response actions Alarm summarization Threshold configuration Antievasive techniques Enables a signature to defeat evasive techniques used by an attacker

Choose a router interface to apply the IPS rule. 4. Choose the traffic flow direction to be inspected by the IPS rules. 5. Specify where the router will find the SDFs. 6. Confirm status of interfaces and signature files. 7. Configure signature alarm severity, event actions, and parameters. 8. Save the Cisco IPS configuration to the router.

17 © 2006 Cisco Systems, Inc. All rights reserved. SND v Summary Cisco IOS IPS uses the underlying routing infrastructure to provide an additional layer of security to deny malicious traffic from inside and outside the network. Cisco IOS IPS works with Cisco IDS, Cisco IOS Firewall, VPN, and NAC solutions, and it is supported by Cisco SDM and CiscoWorks device management software. Using the Cisco SDM software there are basically eight steps to configure Cisco IOS IPS on a router. The Cisco SDM GUI is browser-based and easy to use. Use the Cisco SDM GUI wizard to configure IPS rules. Use the Cisco SDM GUI to configure and tune IPS signatures. Use the Cisco SDM GUI to configure global settings. Using the Cisco SDM GUI, you can save your configuration to the router or to a file on your PC.
