Patrol, Access Control and Site Security Procedures
Patrol fundamentals
Patrol is a systematic, documented activity, not random walking. Understand foot versus mobile patrol, interior and exterior routes, high-risk and low-risk areas, time-stamping methods, and the purpose of irregular patterns so routes are not predictable. Know the value of observation skills: baseline the normal, notice anomalies, and record specifics (time, location, description, action taken).
Access control
Access control has three parts: identifying who may enter, verifying that identity or credential, and recording the event. Know the difference between something you know (PIN), something you have (card, key), and something you are (biometrics), and that combining two factors is stronger. Understand tailgating and piggybacking, visitor management, escort rules, key and card control, and the principle of least privilege. Delivery areas, loading docks and fire exits are classic weaknesses.
Site procedures
Expect questions on post orders, pass-down logs, keys and equipment sign-out, alarm response, lock-up and unlock procedures, and the rule that guards follow post orders unless they conflict with law or safety. Post orders are site-specific instructions; they never authorize unlawful conduct.
Traps
Questions test whether you challenge an unfamiliar person politely rather than assume, whether you leave doors propped, and whether you document a patrol or just complete it. Another trap: treating an alarm as certainly false or certainly real. Respond per procedure, verify, and report.
Rule of thumb
For any access point, ask: who, how verified, recorded where? For any patrol, ask: what did I see, when, and what did I do?
Worked example
A person in a courier jacket follows an employee through a secure door without badging. The guard politely asks them to return to reception for sign-in. That is tailgating prevention, not accusation.
