I'd see this as: non-ssl telnet is no lock. SSH1 is 1 lock. SSH2 is
also 1 lock, but a much better (and more expensive) one. ;-)
Why do I count both as 1 lock? Well, the number of locks has to do
with the security/usability balance: more locks are more secure[1],
but also less convenient. And SSH2 isn't more complicated to use than
SSH1, just better.
Bye, J
[1] Depends on the type of door, of course... a cheap wooden door in a
cheap, weak frame isn't secure, no matter how many locks you put on
it. Worse... 20 locks would probably weaken that door enough to point
that you could just gently push it in (instead of kicking) ;-)
