In addition to an already safe configuration, I use non-standards ports.
As you point out yourself, it keeps the log files clean, which allows me
to focus on the small number of login attempts I get.  This is my main
reason for doing this.

In addition, if OpenSSH (or one of its dependencies) should ever be
subject to a severe security issue, plenty of folks would immediately
start scanning and exploiting the Internet.  A non-standard port would
likely give me a grace period which would allow me to shut down SSH or
take other measures.

Cheers,
Philipp
