ABSTRACT
The unfortunate reality of the twenty-first century is that security issues with international implications arise constantly, and these must be identified and addressed. Annex 17 of the Chicago Convention, titled Security: Safeguarding International Civil Aviation Against Acts of Unlawful Interference, sets out the international SARPs that represent the minimum requirements for aviation security. The need for international security measures was recognized after a series of violent crimes against civil aviation occurred in the 1960s. The reason that security controls vary between countries is that Annex 17 establishes the minimum security standards for international aviation. Annex 17 specifies that States should deploy security measures that help achieve a safe civil aviation system. Rather than observing a single security initiative, the civil AVSEC strategy comprises multiple layers of defence based on a philosophy of unpredictability. Airports Council International (ACI) published guidelines for landside security following the Istanbul attack. The tragedy of 9/11 had a profound impact on aviation security.
