Explain the difference between preventive and detective security measures with examples.

• A. Preventive measures aim to stop incidents, such as access controls and barriers; detective measures detect incidents, such as CCTV and alarms.
• B. Preventive measures and detective measures are the same.
• C. Detective measures prevent incidents, while preventive measures only report them after.
• D. Preventive measures detect incidents; detective measures prevent them.

Answer: (A)

Preventive measures aim to stop incidents before they occur by reducing opportunities for entry or harm. Examples include access controls (card readers, biometrics), locked doors, and physical barriers like fences or turnstiles. Detective measures, on the other hand, are designed to reveal that an incident is happening or has happened so you can respond quickly. Examples include CCTV surveillance, alarms, motion detectors, and security patrols. The key difference is purpose: prevention reduces risk by stopping incidents, while detection alerts you to incidents so you can mitigate consequences. The other options mix up roles or reverse functions, which would undermine how each type of control works.
