Lighting as a Security Control

A.

The correct answer is A. Deterrent.

Explanation:

A deterrent control is designed to discourage potential attackers or intruders from attempting to breach the security of a system, facility, or asset. Deterrent controls are often visible and obvious, making it clear to potential attackers that the risk of detection and/or capture is high.

In this case, adequate lighting on the outside of a building can act as a deterrent control by making it more difficult for someone to approach the building undetected. By illuminating the exterior of the building, potential attackers or intruders may be discouraged from attempting to breach the security of the building, as they would be more easily visible to anyone who might be observing the area.

Compensating controls are used to mitigate the risk of a security control that cannot be implemented. For example, if a particular security control is too expensive to implement, a compensating control might be implemented instead to provide an equivalent level of security.

Detective controls are designed to detect security breaches or incidents after they have occurred. For example, an intrusion detection system might be used to monitor network traffic for signs of unauthorized access or activity.

Preventative controls are designed to prevent security breaches or incidents from occurring in the first place. For example, access controls might be implemented to prevent unauthorized access to a system or facility.

Therefore, the correct answer to the given question is A. Deterrent.
