An attacker sees a building is protected by security guards, and attacks a building next door with no guards. What control combination are the security guards?

A.
Physical/Compensating

B.
Physical/Detective

C.
Physical/Deterrent

D.
Physical/Preventive

Explanation:
Answer C is correct; the guards deterred the attack.

Incorrect Answers and Explanations: A, B, and D: Answers A, B, and D are incorrect. In a different scenario a guard could be any of these, but all are incorrect given the question. Compensating controls compensate for a weakness in another control. Detective controls detect a successful attack during or after it has occurred.
Preventive controls prevent successful attacks.
