Explanation

Detective controls identify and alert on security events after they begin occurring. Movement sensors (A) detect motion and trigger alarms, making them detective controls - they don't prevent entry but reveal that it has happened. Bollards (B) are physical barriers that prevent vehicle intrusion - a preventive control. Firewalls (C) block unauthorized network traffic - also a preventive control. Turnstiles (D) physically restrict unauthorized passage - another preventive control. The key distinction is that detective controls observe and report, while preventive controls block.
