Physical Security Flashcards

What is the primary function of perimeter security at a cargo facility?

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.

What height is generally recommended for perimeter fencing at secure cargo facilities?

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.

What is the purpose of a 'clear zone' on either side of a perimeter fence?

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.

Which lighting condition is most effective for deterring unauthorized access at a cargo facility at night?

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.

What type of lock is recommended for securing cargo containers under international trade security standards?

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.

What does 'defense in depth' mean in cargo facility physical security?

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.
