Which statement correctly distinguishes a procedural control from a physical control?

• A. Physical controls are tangible barriers like a turnstile.
• B. Procedural controls rely on rules and processes, such as visitor sign-in.
• C. Procedural controls require monitoring devices like cameras.
• D. Physical controls are only for fire safety.

Answer: (B)

In security, procedural controls rely on rules and processes to manage access and behavior, rather than on physical barriers. The statement that visitor sign-in exemplifies this is the best distinction because it shows how procedures guide who is allowed in and under what conditions, independent of any hardware.

Physical controls, on the other hand, are tangible barriers like turnstiles, locks, or fences that physically restrict entry. The other options either describe physical controls (A) or misattribute a procedural/control device (C) or make an incorrect claim about physical controls (D).
