I run Fail2Ban on my various servers, and I think all but one of them 
are running SSH on non-default ports.  Coincidentally enough, the only 
server where I ever -- EVER -- get SSH hacker alerts is the one where 
SSH is running on the default port.

By all means, disable root SSH logins too.  The one exception might be 
if you are SSH-ing in from a trusted IP, and you can set that up in your 
sshd_config like so:

AllowUsers  user1  user2  root at 192.168.1.*
