Surprising how few tools there are for this purpose.
pam_tally is a start but not really the full solution I was expecting to
The theory is simply that once you see suspicious activity of any kind
from an IP then there is a good chance that IP is going to scan for
other holes as well so you'd want to shut them down early.
Of course any automatic firewall based on attack signatures might then
be subject to denial of service because of IP spoofing so perhaps thats
why it isn't more common place.
