Subject: OpenSSH is a good choice?

This is my first post, so bare with me.

It is important to distinguish between motivated active attacks
performed by humans, and automated and often poorly crafted worms and
automated attacks. Even though the use of for example non-standard
ports will not stop an attack by intelligent people, the fact is that
most attacks and collection of target lists are based on fairly stupid
automated scripts etc. One might not think that this is something to
worry about, but according to statistics, worms and viruses account
for most of the economical loss.
