Which entity is responsible for perimeter security?

• A. The Federal Government
• B. The Airport Operator
• C. The Local Police
• D. The Airline Security Office

Answer: (B)

Perimeter security is about guarding the boundary between the public area and the secure airport environment. The entity that owns and operates the airport is responsible for that boundary, including fencing, gates, lighting, cameras, patrols, access control, and incident response. This central management ensures a coordinated, consistent defense and rapid coordination with law enforcement as needed. The Federal Government sets overarching security policies and regulatory requirements but does not run the day-to-day perimeter. Local Police handle broader law enforcement and emergency response, not routine perimeter management. The Airline Security Office focuses on protecting aircraft and operations inside terminals and airside areas, not the external boundary. Therefore, the airport operator is the one responsible for perimeter security.
