similar pattern
How do you define "similar pattern"? Detecting similar patterns/signatures is trivial if the signature is known in advance, but how do you know if something is "similar" before it even happens? And if it is KNOWN then it probably already has a signature right? Anomaly based Intrusion Detection/Prevention is very complex, much more complex than just trapping traffic and predicting similar patterns. -- Johnny Calhoun, GCIA Information Security Analyst LURHQ 843-903-4376 opt2 jcalhoun@lurhq.com -------------------------------------------------------------------------- Test Your IDS Is your IDS deployed correctly?
