I like to use a limit rule (ufw limit 22/tcp) for SSH, to discourage brute force attacks. If nothing else, it will help reduce the noise in the log files.

This isn't a replacement for basic precautions such as disabling root login and not allowing password authentication, of course.

I prefer to not limit SSH but use fail2ban instead to remove the noise.
