Re: Automated IDS Signature Generator?

Is there a utility/function/program that automatically generates an IDS
signature based on a recording of a monitored exploit attempt?

It would be quite useless. For one thing, you must see more than one
attempt, since polymorphism is obviously an issue: so, you generally want a
signature which catches most forms of the attack. For another, you
definitely don't want it to generate false positives.

In other words you need to recognize a common pattern between different
exploits, and to avoid including legitimate traffic.

In other words, you need either a very good AI/datamining approach (still
working on it, sorry ;) or a very skilled analyst :)
