It's a policy. There are various ways of responding, the most
"effective" of which is to use ipchains or ipfwadm in Linux to filter
out the traffic from the attacking host. That way the attacker only sees
a "black hole" when they try and contact the victim machine.
One side effect of any of the "active" responses is a potential denial
of service for legit. users though.
