SANSFIRE

Hope all the attendees at SANSFire are having a GREAT time and learning much. Judy Novak had a three hour mini-course on packet crafting using scapy. If you don't know of Judy, she's one of the really top notch intrusion analysts in the world today.
Used to work for the military, now with Sourcefire. Co-authored a really good book with Stephen Northcutt on intrusion analysis (see my reading list to the right on this blog).
