WebApp Sec: Intrusion Detection

["David Robert" <david31900 () rogers com>]

Hello all,

I've been reading this list for some time and I can't help but notice that
there is a lot of information and discussion about securing systems, but
very little about how to detect if you *are* compromised.

This one of my major concerns.  I can advocate all kinds of practices and
procedures, but eventually someone will get through.  So how can I tell?
Especially if they are trying not to leave traces?

Is there a few very simple, dumb things that everyone should do in this
regard?  If so, then I haven't heard them.  If you could list them, or point
me to some good resources, it would be much appreciated.

Thanks,

Securing a web application goes far beyond testing the application using 
manual processes, or by using automated systems and tools. Watchfire's
