ASO ASO Access Control and Perimeter Security 2 — Questions and Answers
Question 1: What is the purpose of a 'man-trap' or 'sally port' at a high-security facility entrance?
- A holding cell for detained individuals on site
- An enclosed entry vestibule where one door must close and lock before the next door can open, preventing simultaneous access (Correct answer)
- A perimeter fence designed to trap trespassers
- A dual-camera system mounted above the entrance
Correct answer: An enclosed entry vestibule where one door must close and lock before the next door can open, preventing simultaneous access
A man-trap creates an airlock-style entry where only one door can be open at a time, ensuring each person is individually verified before proceeding.
Question 2: When logging vehicles into a secured parking area, which information is MOST critical to record?
- Vehicle color preference of the driver
- License plate number, make/model, driver name, and entry/exit time (Correct answer)
- The radio station playing in the vehicle
- Whether the vehicle is foreign or domestic
Correct answer: License plate number, make/model, driver name, and entry/exit time
Accurate vehicle logs create an auditable record that can be used to investigate incidents or unauthorized access.
Question 3: Which of the following is a physical perimeter security measure designed to prevent vehicle ramming attacks?
- Chain-link fencing alone
- Anti-ram bollards or vehicle barriers rated to stop moving vehicles (Correct answer)
- Warning signs posted at the entrance
- Speed bumps on the interior access road only
Correct answer: Anti-ram bollards or vehicle barriers rated to stop moving vehicles
Anti-ram bollards are purpose-built barriers that can absorb or stop a vehicle traveling at speed, protecting buildings and people from vehicle-borne attacks.
Question 4: During an access control shift, an officer discovers that an employee's badge has been reported lost or stolen. The CORRECT action is to:
- Continue allowing the badge to function until a replacement is issued
- Immediately deactivate the badge in the access control system and notify the supervisor (Correct answer)
- Tape a 'lost' notice over the badge reader
- Issue a temporary badge to the employee without deactivating the lost one
Correct answer: Immediately deactivate the badge in the access control system and notify the supervisor
A lost or stolen badge must be deactivated immediately to prevent unauthorized use by whoever found or stole it.
Question 5: What does 'perimeter lighting' primarily accomplish for a secured facility?
- Reduces the facility's electricity bill by concentrating power at the fence line
- Eliminates shadows along the perimeter to deter intrusion and support camera and guard observation (Correct answer)
- Provides decorative illumination for visiting clients
- Signals the start and end of shift changes
Correct answer: Eliminates shadows along the perimeter to deter intrusion and support camera and guard observation
Adequate perimeter lighting removes concealment opportunities that intruders rely on and improves the effectiveness of both human guards and surveillance cameras.
Question 6: A visitor attempts to enter a restricted area without an escort after signing in at the lobby. The armed officer on post should:
- Allow entry since the visitor already signed in at the front desk
- Intercept the visitor, explain the escort policy, and contact the host to provide an escort (Correct answer)
- Immediately detain the visitor and call police
- Direct the visitor to a different entrance where escort is not required
Correct answer: Intercept the visitor, explain the escort policy, and contact the host to provide an escort
Signing in at the lobby does not grant unescorted access to restricted areas; the officer must enforce escort policy and facilitate the proper procedure.
