Which authority oversees airport security regulations?

The Transportation Security Administration (TSA) is the authority that oversees airport security regulations. Established in the aftermath of the September 11 attacks, the TSA's primary mission is to ensure the security of the nation's transportation systems, including airports. It has the responsibility to enforce security measures that protect passengers and cargo from potential threats. This includes the implementation of screening procedures for passengers, baggage, and cargo, as well as the training of security personnel.

The TSA operates under the Department of Homeland Security (DHS), which coordinates various aspects of national security, but the specific oversight of airport security falls directly under the TSA. The agency develops and enforces security regulations that airports and airlines must follow to maintain a secure travel environment.

While the Federal Aviation Administration (FAA) is responsible for the safety of civil aviation and the National Transportation Safety Board (NTSB) investigates transportation accidents, their roles do not specifically include the oversight of airport security regulations in the same capacity as the TSA.
