Which document is a key origin of airport security regulations?

The key document that serves as a foundation for airport security regulations is the ICAO Annex 17. This annex, titled "Security: Safeguarding International Civil Aviation Against Acts of Unlawful Interference," establishes the global standards and recommended practices aimed at enhancing the security of civil aviation. It outlines the necessary measures that states must implement to protect against unlawful acts, such as terrorism and sabotage, thereby ensuring the safety of passengers and the integrity of aviation operations.

Annex 17 is part of the broader framework established by the International Civil Aviation Organization (ICAO) which is critical for creating a standardized approach to aviation security across countries. This uniformity is essential, as aviation is a global industry that requires cohesive policies to effectively mitigate security threats.

While the ICAO Safety Handbook, Passenger Rights Manual, and Environmental Policy Document are important in their respective contexts, they do not primarily focus on the regulatory framework for airport security like Annex 17 does. The significance of Annex 17 in shaping and guiding airport security regulations cannot be overstated, as it directly influences national legislation and security protocols worldwide.
