Strong agreement!  There are endless dictionary attacks to ssh.  This
sometimes scares people but for no good reason.  If you have a strong
passwords, and everyone should have either strong passwords for ssh or
blocked passwords, then there is no danger.  There is no need to shy
away from ssh simply because the Internet is a hostile place.

One of the best tools to mitigate the noise of ssh attacks is
fail2ban.  Like Jerry I always install fail2ban and it does a
marvelous job of managing the automatic banning of abusive IPs.
Fail2ban can be expanded upon to manage web service attacks such
abusive POST attacks and other such things.  Definitely a worthy tool
that is always on my servers.
