Layered Security Approach

A.

The security control being employed in the scenario is an administrative control.

Administrative controls are security measures that are implemented through policies, procedures, and training. They are designed to ensure that personnel adhere to security policies and procedures, and that they are aware of the security risks associated with their job responsibilities.

In the scenario given, the security guards are responsible for verifying the authorization of all personnel entering the facility. This is an administrative control because it is a policy and procedure that is implemented to control access to the facility. The security guards are trained to enforce the policy and ensure that only authorized personnel are allowed to enter the facility.

Corrective controls, on the other hand, are implemented to correct or mitigate security incidents or breaches. Deterrent controls are designed to discourage potential attackers or intruders from attempting to breach security measures. Compensating controls are implemented to supplement other controls that may not be effective in certain situations.

In summary, the BEST term that describes the security control being employed in the scenario is an administrative control.
