When it comes to attacks on the Internet, doing simple things to get rid of the stupid bots means kicking 90% of attacks out. No, it won't work against a determined foe, but it does something useful.

Same goes for setting SSH to a random port. Logs are so much cleaner after doing that.

Setting a random SSH port and limiting it to 3/min saw failed login attempts fall by 99% and jailed IPs fall to 0.
