Chris I have been using it from a long time ago. The main use is to verify what the firewall and IDS logs are trying to tell me. Although, my first wonderful experience using packet capturing systems (tcpdump with 128 bytes of payload) was when a customer denounced to my employeer (a TELCO) about DNS poisoning. I worked on network forensics by tracking and reconstructing packet by packet to show to this customers that we never were exploited by a DNS poisoning attack, and our DNS resolved perfectly well.

Id like to see what the pro's think about capturing and storing packet payloads from firewalls, ids, etc... everything rather than just loggin the incidents. Im trying to explain to my management how useful the payloads could be if we were ever to really need them, say from a forensics point of view. To give another example, one time I was seeing lots of firewall drops, I could tell what ports, src and dest. but no packet data. To everyone involved it looked like a worm trying to spread. Well in the end it wasnt, infact is was something that was nice to know about, but it was not hostile traffic. But if I had been able to see the payloads i could have seen the data request and known from the start what it was, or was not. What would be really great, is a whitepaper covering this, or enough info/facts that I could throw one together. thanks!
