While I love LaBrea, I think it's a bad idea to 'incorporate' into
Snort. It's a separate application, period. And it should run on a
separate box. A lot of folks are running Snort on a stealth interface
and that would not be able to send the packets LaBrea sends to keep the
TCP 'alive'. Also, LaBrea creates bandwidth by trapping the TCP
connections, which can't be good for an IDS that is busy decoding
Also, Snort would have to be multi-threaded so that it can keep TCP
connections alive while at the same still doing its regular job.
An IDS is an IDS is an IDS....
I use LaBrea on one box and Snort (on a stealth interface/ro-cable) on
another box. Snort logs the scan attempts just fine, while LaBrea keeps
them tarpitted. The run fine in tandem, but on separate boxes.
