Which of the following is NOT a key component of airport security?

Customer feedback is not considered a key component of airport security because airport security protocols primarily focus on the protection of passengers, staff, and the overall operational security of the airport. The main security components include risk assessment, which involves identifying potential threats to ensure appropriate measures are in place; emergency response, which prepares personnel to handle incidents effectively; and surveillance, which encompasses monitoring activities and behaviors to detect suspicious actions or breaches.

While customer feedback can inform service improvements and enhance passenger experience, it does not directly contribute to the foundational aspects of ensuring safety and security within the airport environment. Hence, it does not play a critical role in the core framework of airport security operations.
