Which component may be part of physical security measures?

Physical security measures are essential in protecting airport facilities and ensuring the safety of passengers and personnel. The correct response focuses on the implementation of both physical and electronic barriers. These barriers can include security fences, access control systems, surveillance cameras, and other technologies designed to prevent unauthorized access and monitor activities in sensitive areas.

By creating layers of security that deter or detect potential threats, these measures play a critical role in the overall security strategy of an airport. They not only help in controlling access to restricted areas but also enhance the effectiveness of security personnel by providing them with tools to monitor, assess, and react to security incidents.

The other options do not specifically relate to physical security measures. For example, enhanced passenger amenities focus more on traveler experience rather than security. Increased flight operations might pertain to aviation efficiency but does not contribute directly to physical security. Weather-related emergency plans address potential safety concerns during adverse weather conditions but are not part of the physical security infrastructure. Thus, the emphasis on physical and electronic barriers as a fundamental component underscores their significant role in safeguarding airport environments.
