I said many times - just use non standard port. Number of hackerts who
discover this port wil decrease approx 10,000 times, to
almost 0 (number).

(Of course, except if you are a bank).

Other approach exists as well - SecureID on firewall. Login to firewall,
authenticate, and have dynamic access list which opens ssh for you (and
still keep ssh on port != 22).

Isn't it just good security practice to limit telnet/SSH access to

to access something, call your NOC, and have them temporarily allow
your
dynamic address for SSH.  When a hacker finds an open SSH host, they
think two things - This host is important to someone, and that they
need
more doughnuts...
That is an excellent idea.  As soon as I hire a NOC for my personal
boxes, I'll get right on that.  But, since I Am Not An Isp, I doubt
that is going to happen soon.

Remember, not every box on the Internet is supported by a whole
network of resources (physical and human).
