Explanation

When the goal is specifically to protect a door against unauthorized access, a lock is the most direct and effective control. Locks physically secure the door mechanism itself, requiring authenticated credentials (key, PIN, card, biometric) to operate. Turnstiles, fences, and barriers are perimeter controls designed for open areas or traffic flow points-they are not designed to secure a specific door. For door-level access control, locks are the primary and most effective solution.
