A human guard monitoring a hidden camera is an example of which type of control?

A human guard monitoring a hidden camera is considered a detective control because it is designed to identify and monitor activities or security breaches after they occur. Detective controls are utilized to detect incidents, failures, or unauthorized actions that have already taken place. In this case, the guard's role involves observing the footage captured by the camera to recognize any suspicious behavior or security threats in real-time, enabling a prompt response to incidents.

The nature of detective controls emphasizes their purpose in discovering and reporting issues rather than actively preventing them from happening or serving as a deterrent against potential threats. While preventive controls aim to stop incidents before they occur and deterrent controls seek to discourage undesirable actions through visible security measures or threats of consequence, the primary function of the guard monitoring the camera aligns directly with the goals of detection.
