What is an example of a physical security measure at an airport?

Fencing and surveillance cameras are vital components of physical security at an airport. These measures create physical barriers that protect restricted areas and monitor activities in real-time. Fencing helps to prevent unauthorized access to sensitive zones, while surveillance cameras enable the continuous observation of these areas, deterring potential threats and ensuring that any unusual activity can be promptly addressed. Together, they establish a foundational layer of security that is essential for the protection of passengers, staff, and airport infrastructure.

Other options, like passenger announcements and security training for staff, focus more on communication and personnel preparedness rather than direct physical security measures. Frequent security meetings contribute to strategic discussions about security but do not provide the immediate physical protection that fencing and surveillance can deliver.
