An open port 22 can be made safe. There are numerous articles available
on the net like the following:

http://www.debian-administration.org/articles/573
For the particular issue you had, probably the best option is to use
the AllowGroups option in sshd_config to restrict ssh access to users
of a specific group. On my machine I have
AllowGroups sshlogin
and then add any specific users to that group.
Running SSH on a non standard port also helps.
Cheers,
Erik
