I started scratching my head after realizing that I need to have a custom set of signatures trimmed to fit the clients requirement. Let's assume I disabled and retired not needed signatures and tuned others, making one staging IPS trimmed and ready to fire only those relevant signatures. Now my question is about how to deploy this prepared signatures to other live IPS sensors? And the most important question. Is there a mechanism that keeps those previously deployed signatures after signatures update from Cisco site ?
