Yes this is why I stated a "hyperactive" NID at work (or maybe a hyperactive
admin ). Unfortunately I have run into a lot more of these lately as people
seem to think it is a cool thing to do. Until I shun them from there next
hop:-)

One way to detect a NIDS is to launch attacks and see if you are then
shunned from the network. This is a good indication that a hyperactive
NID
is at work. Also if your connection gets reset when you attempt an
exploit
that is another tip-off. As far as fingerprinting goes, if you where
knowledgeable about default rulesets you might be able to determine a
NID
by
its reactions, or lack of action, to certain attacks.


I think think you'll find that most IDS have the auto response facility
turned off
