Re: analysing captured packets

[Dan Goldberg <dan () madjic net>]

This is a good place to start learning about "what to look for":
http://www.packet-level.com/productsServ.htm#labkit
(I am not affiliated - nor have I been to the training)

Of course the SANS Institutes Intrusion Detection course is a great
place to develop hands on experience with analysis and the mastering
packet analysis course form SANS to.
(I am loosely affiliated with the SANS institute but do not gain
personally from these activities)
