Hi,

working on a test concept for FW-Fset I'm seeking for info on the
reassembly method the integrated IDS system is doing.
Don't mix with PIX or NetRanger IDS, they probably handle it quite different.
The method of reassembly will affect the way to test and interpret
test results in terms of false positives and others.

Probably it's doing at least reassembling frags, but whats about
  - reordering frags to come along in right sequence
  - stream reassembly
  - state tracking

Yes, I read Marcus paper on IDS benchmarking ;-)

I assume, CBAC is doing frag reassembly anyway (found this in the docu,
but nothing on IDS).

TIA
---Maik
