Which of the following controls would be the MOST comprehensive in a remote access network
with multiple and diverse subsystems?
Password implementation and administration
The most comprehensive control in this situation is password implementation and administration.
While firewall installations are the primary line of defense, they cannot protect all access and,
therefore, an element of risk remains. A proxy server is a type of firewall installation; thus, the same
rules apply. The network administrator may serve as a control, but typically this would not be
comprehensive enough to serve on multiple and diverse systems.
