Which of the following is a primary goal of airport security measures?

Preventing unauthorized access to secure areas is a fundamental objective of airport security measures. This focus ensures that only individuals with the proper credentials—such as airport staff, law enforcement, and passengers—are allowed into restricted zones. These secure areas are critical to maintaining the safety of passengers and aircraft by mitigating risks associated with potential threats, such as terrorism or other criminal activities.

Security protocols like screening processes, access controls, and surveillance systems are put in place to safeguard these areas from any unauthorized individuals who might pose a security threat. This approach reinforces the integrity of airport operations as a whole, promoting safety and confidence among travelers and personnel alike.

Other options, while they may contribute to operational efficiency or customer service, do not align as closely with the overarching purpose of ensuring security at airports.
