B.

A callback feature hooks into the access control software and logs all authorized and unauthorized access
attempts, permitting the follow-up and further review of potential breaches. Call forwarding (choice D) is a
means of potentially bypassing callback control. By dialing through an authorized phone number from an
unauthorized phone number, a perpetrator can gain computer access. This vulnerability can be controlled
through callback systems that are available.
