Which of the following BEST restricts users to those functions needed to perform their duties?

A.
Application level access control

B.
Data encryption

C.
Disabling floppy disk drives

D.
Network monitoring device

Explanation:
The use of application-level access control programs is a management control that restricts access by limiting
users to only those functions needed to perform their duties. Data encryption and disabling floppy disk drives
can restrict users to specific functions, but are not the best choices. A network monitoring device is a detective
control, not a preventive control.
