Answer: D
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
and 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.
