Who is primarily responsible for the security implementation at airports?

The Transport Security Administration (TSA) is primarily responsible for the security implementation at airports in the United States. Established in response to the events of September 11, 2001, the TSA was tasked with enhancing airport security to prevent acts of terrorism and ensure the safety of travelers. The agency develops and enforces security regulations that must be followed by airlines and airports, including screening passengers, baggage, and cargo.

Training personnel, deploying advanced screening technology, and coordinating efforts among federal, state, and local agencies are key functions of the TSA. While it collaborates with local law enforcement and private security firms to enforce security protocols, the ultimate responsibility for the regulations and implementation resides with the TSA. This makes it the central authority for managing and overseeing airport security measures effectively.
