Question

A security manager needed to protect a high-security data center, so the manager installed a mantrap that can detect an employee's heartbeat, weight, and badge. Which of the following did the security manager implement?

Options

AA physical control
BA corrective control
CA compensating control
DA managerial control

Explanation

NOTE: The listed correct answer is C (compensating control), but A (physical control) is the most accurate classification. A mantrap - a physical double-door entry system that validates identity before allowing access - is fundamentally a physical security control that directly enforces access through physical means (biometric sensors, weight detection, badge verification). A compensating control is one that substitutes for a primary control that cannot be implemented for some reason. Unless the question intends that the mantrap compensates for some other missing access control, A is the more precise answer for this scenario. Mantraps are textbook examples of physical controls.
