I use a combination of the already mentioned DenyHosts, and also I turn
off password authentication. I then generate SSH key pairs, which
ensures that only machines I want connecting that have the key, can
connect.

With that and the DenyHosts utility, when someone offends a) they can't
connect to begin with because of the keys, and b) DenyHosts adds them to
a deny file and won't allow them to connect again from the offending IP.

There are a number of ways to accomplish what you seek.
