Linux Tutorial - Security - What You Can Do About It - Modem Security

Modems

Is access to you machine possible by modem? I had worked for one company for more than year before I found out that there was a modem on the system. It was connected to a terminal server that has it's own password, so you actually needed two passwords to get into he system. However, this is important for every system administrator to know.

What are the characteristics of the modem and the port? Is hangup forced when user logs out? If the connection is broken does the system log the user out? What are the permissions on the port? Can it be used by normal users to dial out? Are the answers to these questions in keeping with your company security policy.
