Configuring the Status of Signatures can be a daunting task. Especially if you have multiple Cisco IPS systems. Using the Cisco IPS signature status change script / web form is a huge time saver. So when you get your email updates from Cisco about the new signature releases you can just input what you want to enable and disable into this web form. Type in the name of the signature definition in the the first line then click the add signature button to add more web form fields to the web form.
It’s important to keep the number of enabled signatures as low as possible – any disabled signatures should be retired.
The result of the submit button will yield all the commands necessary to enter into your Cisco ips CLI.
The results will look like this
service signature-definition sig0
signatures 6213 0
signatures 6456 0
Once you copy the output just log in to your IPS sensor via ssh and enter configuration terminal mode, config t. Paste the list of command and give the sensor while to process the series. Upon completion of processing the IPS will ask if you want to apply the changes. type “yes” and hit enter.
