I'm developing a graduation Project "Network Based Intrusion Detection System
using Signature Analysis"
I've already finished some phases
1. Packet Capture
2. Packet Decoding
3. And i'm working now in the detection Engine

I really need some information about different Attacks
(using any protocol ) and the corresponding packet format
for this attack,I thought you might help me, or at least
show me where i can find help.
i hope i'm not annoying you , but my graduation project have
to be handed over the next month ,and i still have a lot of
work to do.
