this is in-band. if as you say you are accessing from another network then
this is where the encryption kicks in being useful, however that raises
another question - do you just allow any host to connect providing they
can authenticate? i know my login ports are restricted at both network and
host level to specific authorized addresses...

exactly, its probably easier to hack the box by other means than sniffing
auth details!
