Which of the following is NOT a form of computer/network
surveillance?

A.
Use of CCTV cameras

B.
Use of network sniffers

C.
Keyboard monitoring

D.
Review of audit logs

Explanation:
CCTV cameras fall under the category of physical surveillance.
Answers a and b are forms of active surveillance. These types of surveillance
require an organizational policy informing the employees that
the surveillance is being conducted. Additionally, warning banners
describing the surveillance at log-on to a computer or network should
be prominently displayed. These banners usually state that by logging
on, the user acknowledges the warning and agrees to the monitoring.
Answer “Review of audit logs” is a passive form of computer/network surveillance.
