Building Cisco IDS 3.0(3) Custom Signatures

Article Description

When using a signature-based Intrusion Detection System (IDS), keeping signature definitions up to date is crucial to maintaining optimum protection of your network resources. Earl Carter discusses building Cisco IDS 3.0(3) custom signatures in this timely article.


Cisco IDS 3.0 provides a very robust custom signature creation capability. You can very easily create new signatures to enhance the protection of your network against new threats. You can also use this capability to tune existing signatures so that your Cisco IDS operates more effectively considering your unique network configuration. Furthermore, since all of your custom signatures and tuning parameters are incorporated into a user configuration file, this information remains in effect even after software updates to the Cisco IDS.
