This ratio detection doesn't need to shutdown anything, just syslog the fact so that admins have something in their logs like SYN/ACK RATIO 33:1 POSSIBLE HACKER ATTACK which will make them sit up and take notice.
Ah, you're an optimist.
Most sysadmins would simply ignore whatever warnings they get as long as their internal users aren't complaining.
And half of them wouldn't know what SYN/ACK ratio is.

As long as the attacks were logged another provider (like their upstream provider for example) can come along and say "we traced the attack to your network, what sort of traps were logged". If they are totally clueless they can at least set up the traps and traplogs (possibly with some help) at that point and get the next attack. Curtis
