Answer: B
The authorization and authentication of users is the most
significant aspect in a telecommunications access control
review as it is a preventive control. Weak controls at this
level can affect all other aspects. The maintenance of
access logs of usage of system resources is a detective
control. The adequate protection of data being transmitted
to and from servers by encryption or other means is a method
of protecting information during transmission and is not an
access issue. The accountability system and the ability to
identify any terminal accessing system resources deal with
controlling access through the identification of a terminal.
