  While you can construct something passable on the VAX, it is vulnerable to
attack by someone who gains privileged access to the VAX. With the callback
code buried in the modem, such a person would need to gain physical access
to the modem *and* be well-versed in the modem's firmware.

  Outboard boxes between the modem and the VAX fall somewhere in between.

  If you are doing this for real security (as opposed to giving management
warm fuzzies) you should also study the costs/benefits of a modem/outboard
box-based approach.
