An IS auditor observed that some data entry operators leave
their computers in the midst of data entry without logging
off. Which of the following controls should be suggested to
prevent unauthorized access?
A. Encryption
B. Switch off the computer when leaving
C. Password control
D. Screen saver password
Answer / guest
Answer: D
Since data entry operators have to attend to other
assignments in the midst of data entry and the nature of the
assignments are such that they do not logoff the computer,
screen saver password is the only effective control to guard
against unauthorized access. Encryption does not prevent
access to the computer, it only guards against disclosure of
the confidential contents of the files. Switching off the
computer without properly shutting it down is not advisable.
Password control takes place when logging on to
anapplication and is not effective in this scenario.
