Greetings! I am relatively new to VMS and the VAX world and I have been assigned the task of developing/finding a security call-back program for our system. I was wondering if there may already be something available before I begin hacking my way through this assignment. If not would it be best to write this in 'C' or in DCL?? Thanks in advance, L. Foltz

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.
