The Transportation Security Administration (TSA) is a United States government agency that is responsible for providing security for the nation's transportation systems. The TSA was created in response to the September 11, 2001 terrorist attacks, and it is a part of the Department of Homeland Security.
The TSA is responsible for securing the nation's airports, highways, railroads, ports, and other transportation systems. The agency uses a variety of measures to ensure the security of these systems, including the use of advanced technology, such as x-ray machines and explosives detection systems, and the deployment of security personnel.
The TSA employs a large workforce to carry out its mission. This workforce includes transportation security officers, who are responsible for screening passengers and baggage at airports, as well as other security personnel who work in various roles to ensure the security of the nation's transportation systems.
In addition to its security efforts, the TSA also works to educate the public about transportation security and to promote awareness of the steps that individuals can take to protect themselves and their communities. The agency also plays a key role in coordinating with other federal, state, and local agencies to ensure the safety and security of the nation's transportation systems.
