Re: Is Marty Lying?

Peter:

Intrusion Detection systems are designed to detect intrusions. Period.
No one AFAIK has yet developed the Intrusion Prediction system. If you
have an alpha version lying around, pls respond with a link. I'm sure
that you will quickly be deluged with download requests =;^)

Reactive is the nature of the beast, a point that has been rehashed many 
many times here and elsewhere. No finite state machine can anticipate or 
detect the virus that I am right now writing, unless I foolishly make part
of the binary match an existing sig. there will *always* be a latency
between action and response. One of the things that people on this list
do is attempt to assist each other in minimizing that latency.

Now, if we could only get some of the vendors onboard >-)
