Summary

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.
