Re: third party utility to kill ...

The snort FAQ describes why trying to invoke an external process from an IDS is a generally bad idea (hint: this creates a security hole that allows your IDS to be bypassed by causing it to waste so much time invoking processes it starts missing packets.).

Read the faq:

http://www.snort.org/docs/faq.html#5.9

And yes, the FAQ mentions a bit about the speed of this on windows, but it's not acceptably fast to do in *nix either.

I want to make use of tcpkill by Dugsong.

Is there a way I can call this program once an alert, say web-iis cmd.exe,
is sensed by snort, then snort is going to execute tcpkill -9 <target_ip>?
