Not in my opinion. I run a little script I wrote that automatically adds

likely attack route might be HTTP or SMTP, so why wait. This is on my
personal server. Here where I work, we're even more strict.

I had a similar set up, but it was quite clunky. Following advise from
this list and others I now firewall port 22 to a few locations (e.g.
work), and also run ssh on a high port.

This doesn't necessarily make things any safer, but has reduced my log
noise drastically.
