Help! "They" want me to shut down my dial-ins unless I can
make them "secure". Suggestions?
I'm thinking of a few approaches, but I don't know what is
commercially available.
1. Software to run on 4.3 BSD (Vax 750) or SunOS 4.0.1
(Sun 4) to implement call-back using the existing modems.
2. Black boxes to sit between the phone line and the
modem and perform call-back or other verification.
3. Black boxes to sit between the modem and the cpu and
perform call-back or other verification.
4. Terminal server with modems attached, where call-back
or other security measures are implmented in the terminal
server. Once the terminal server grants access, user
would connect to a specific host, using telnet or rlogin.
5. Call-back modems. (Icky-poo. Makes upgrading to new
modem technologies very difficult.)
What do y'all think?
