Which concept is described as security measures designed to prevent unauthorized access across multiple security layers in the airport?

• A. Passenger Screening
• B. Outer Perimeter
• C. Sterile Area
• D. Layers of Security at the Airport

Answer: (D)

Layered security at the airport is a defense-in-depth approach where security measures are placed at multiple points to block unauthorized access. By having several barriers—perimeter controls, screening of passengers and baggage, access control to restricted areas, and the sterile area—the system creates multiple chances to detect or deter threats, so breaching one layer doesn’t grant easy entry. The option that best describes this across-the-board approach is layers of security at the airport. The other choices refer to individual elements rather than the integrated, multi-layer strategy as a whole.
