Changing port numbers will not stop a talented person who is intent on
breaking into your network.  However, it will stop (or at least slow
down) the script-kiddies, worms, and others out there who are just
scanning for misconfigured or unpatched applications.  Switching SSH to
a non-standard port completely emptied my log files of bad connection
attempts.  Now, if someone attempts to break in, it will be VERY obvious
in the logs where before, it would have been buried in all of the other
garbage.

Of course.  No one is suggesting that changing port numbers is all you
need to do.  It is just one more thing that you can do to slow down the
attackers.
