openssh concerns

[Darren Reed]

If this hasn't been mentioned already, disable password logins
in sshd_config and require RSA authentication only.

I do this on all hosts I administer that are internet accessible
and it allows me to confidently ignore all of the password
guessing attacks, resulting in peace of mind.
