CSA Physical Security 1 — Questions and Answers
Question 1: What is the primary function of perimeter security at a cargo facility?
- To detect and deter unauthorized entry into the facility grounds (Correct answer)
- To mark the boundaries of the property for zoning purposes
- To guide delivery vehicles to the correct loading dock
- To separate cargo storage areas from administrative offices
Correct answer: To detect and deter unauthorized entry into the facility grounds
Perimeter security is the first line of defense, designed to detect and prevent unauthorized access before an intruder reaches the facility.
Question 2: What height is generally recommended for perimeter fencing at secure cargo facilities?
- At least 8 feet high, often with barbed or razor wire at the top (Correct answer)
- 4 feet, sufficient to mark the boundary
- 6 feet with a decorative finish
- 10 feet, always with an electric charge
Correct answer: At least 8 feet high, often with barbed or razor wire at the top
Industry standards typically require perimeter fencing of at least 8 feet with a topping of barbed or razor wire to deter climbing.
Question 3: What is the purpose of a 'clear zone' on either side of a perimeter fence?
- To eliminate concealment opportunities and provide visibility for detecting intruders (Correct answer)
- To allow vehicles to turn around near the fence line
- To meet fire code requirements for evacuation pathways
- To provide space for landscaping that enhances the facility's appearance
Correct answer: To eliminate concealment opportunities and provide visibility for detecting intruders
Clear zones remove vegetation and objects that could hide intruders or allow them to approach undetected from either side of the fence.
Question 4: Which lighting condition is most effective for deterring unauthorized access at a cargo facility at night?
- Consistent, well-distributed lighting that eliminates dark spots along the perimeter and entry points (Correct answer)
- Motion-activated lights that turn on only when movement is detected
- Red security lighting that is visible but doesn't impair vision
- Floodlights aimed only at the main entrance
Correct answer: Consistent, well-distributed lighting that eliminates dark spots along the perimeter and entry points
Consistent lighting without dark spots prevents intruders from using shadows to approach undetected.
Question 5: What type of lock is recommended for securing cargo containers under international trade security standards?
- ISO 17712-compliant high-security bolt seals or padlocks with a minimum shackle diameter of 9mm (Correct answer)
- Standard padlocks available at hardware stores
- Electronic keypad locks
- Combination locks with four-digit codes
Correct answer: ISO 17712-compliant high-security bolt seals or padlocks with a minimum shackle diameter of 9mm
ISO 17712 sets the benchmark for high-security seals used in international trade, ensuring resistance to tampering.
Question 6: What does 'defense in depth' mean in cargo facility physical security?
- Using multiple overlapping layers of security so that defeating one layer still leaves others in place (Correct answer)
- Placing security guards at every point inside the facility
- Installing the highest quality locks on all doors
- Training security staff in hand-to-hand combat techniques
Correct answer: Using multiple overlapping layers of security so that defeating one layer still leaves others in place
Defense in depth uses layered security so that a breach of one control does not give full access — each layer slows and detects intruders.
