How about project Darknet and sinkholes and monitoring dark ip space,
worms and botnets usually scans blindly right and left, so there is a
good chance you will get a glimpse on infected hosts if thats what you
want, i catch infected hosts by looking at apache access logs and i see
alot of scans,
and Randy for that i change the ssh port to a higher one :)

it's enough of a pita to clean up the syslogs from all the 25k/day
password attacjs per host, when one does not have password ssh
even enabled.
