One would hope so, assuming authorized_keys and proper pass
phrases (but then putty and others allow this from the Microsoft
Virus, Windows and I don't trust anything coming from Windows).

On the few systems where we permit ssh authentication with user
name and password, access is tightly controlled via tcp_wrappers
to specific IP addresses.

Recently we have been using OpenVPN to allow secure access from
remote users which makes restricting ssh access easier when
people are roaming so can't be easily identified by IP address.

Cutting the space budget really restores my faith in humanity.  It
eliminates dreams, goals, and ideals and lets us get straight to the
business of hate, debauchery, and self-annihilation.
