The Transportation Security Administration (TSA) is a U.S. federal agency within the Department of Homeland Security (DHS) responsible for the security of the nation's transportation systems. Established in response to the September 11 attacks, its primary mission is airport security and the prevention of aircraft hijacking, screening passengers and baggage at over 450 U.S. airports. The agency also oversees security for highways, railroads, ports, and pipelines. With a fiscal year 2023 budget of $9.70 billion and over 47,000 employees, the TSA utilizes technologies like millimeter wave scanners and programs such as TSA PreCheck.

The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security (DHS) that has authority over the security of transportation systems within and connecting to the United States. It was created as a response to the September 11 attacks to improve airport security procedures and consolidate air travel security under a combined federal law enforcement and regulatory agency. The TSA develops key policies to protect the U.S. transportation system, including highways, railroads, bus networks, mass transit systems, ports, pipelines, and intermodal freight facilities. It fulfills this mission in conjunction with other federal, state, local and foreign government partners. However, the TSA's primary mission is airport security and the prevention of aircraft hijacking. It is responsible for screening passengers and baggage at more than 450 U.S. airports, employing screening officers, explosives detection dog handlers, and bomb technicians in airports, and armed Federal Air Marshals and Federal Flight Deck Officers on aircraft. At first a part of the Department of Transportation, the TSA became part of DHS in March 2003 and is headquartered in Springfield, Virginia. As of the fiscal year 2023, the TSA operated on a budget of approximately $9.70 billion and employed over 47,000 Transportation Security Officers, Transportation Security Specialists, Federal Air Marshals, and other security personnel. The TSA has screening processes and regulations related to passengers and checked and carry-on luggage, including identification verification, pat-downs, full-body scanners, and explosives screening. Since its inception, the agency has been subject to criticism and controversy regarding the effectiveness of various procedures, as well as incidents of baggage theft, data security, and allegations of prejudicial treatment towards certain ethnic groups.

TSA has used two kinds of full body imaging technology since first deploying them in airports in 2010. Previously backscatter X-ray scanners were used which produced ionizing radiation. After criticism the agency now uses only millimeter wave scanners which use non-ionizing radiation. The TSA refers to both systems as Advanced Imaging Technologies or AIT. Critics sometimes refer to them as "naked scanners," though operators no longer see images of the actual passenger, which has been replaced by a stick figure with boxes indicating areas of concern identified by the machine. In 2022, TSA announced it will allow passengers to select the gender marker of their choice and alter algorithms used by the machines to be inclusive of transgender, nonbinary, and gender-nonconforming individuals. [...] At the helm of the TSA is the administrator, who leads the organization's efforts in safeguarding the nation's airports, railways, seaports, and other critical transportation infrastructure. Assisting the administrator is a deputy administrator, whose role is to provide support and guidance in executing the agency's mission. In addition, the TSA benefits from the expertise and leadership of several deputy assistant administrators and other executive officers, who contribute their knowledge and skills to various aspects of the agency's operations. Together, this structured leadership team forms the backbone of the TSA, working collectively to uphold and enhance the security of the nation's transportation networks. The executive assistant administrator for law enforcement is also the [...] The TSA, on their website, states that they have "implemented strict measures to protect passenger privacy which is ensured through the anonymity of the image," and additionally states that these technologies "cannot store, print, transmit or save the image, and the image is automatically deleted from the system after it is cleared by the remotely located security officer." This claim, however, was proven false after multiple incidents involving leaked images. The machines do in fact have the ability to "save" the images and while this function is purported to be "turned off" by the TSA in screenings, TSA training facilities have the save function turned on.
- Security Screening | Transportation Security Administration - TSA
TSA uses millimeter wave advanced imaging technology and walk-through metal detectors to screen passengers. Millimeter wave advanced imaging technology safely screens passengers without physical contact for metallic and non-metallic threats, including weapons and explosives, which may be concealed under clothing. Generally, passengers undergoing screening will have the opportunity to decline AIT screening in favor of physical screening. However, some passengers will be required to undergo AIT screening if their boarding pass indicates that they have been selected for enhanced screening, in accordance with TSA regulations, prior to their arrival at the security checkpoint. This will occur in a very limited number of circumstances. The vast majority of passengers will not be affected. See [...] TSA counts on the traveling public to report unattended bags or packages; individuals in possession of a threatening item; and persons trying to enter a restricted area or similar suspicious activities at airports, train stations, bus stops and ports. If You See Something, Say Something™. Report suspicious activity to local law enforcement. Passenger screening at the airport is part of TSA’s layered approach to security to get you safely to your destination. TSA’s screening procedures are intended to prevent prohibited items and other threats to transportation security from entering the sterile area of the airport and are developed in response to information on threats to transportation security. Learn more by viewing this timeline of transportation security events and measures. ## [...] Claims: If your property is lost or damaged during the screening process, you may file a claim with TSA. If your property is lost or damaged during transport to the plane or baggage claim, please contact your airline. Locks: TSA has been provided universal "master" keys under agreements with Safe Skies Luggage Locks and Travel Sentry so that certain branded locks may not have to be cut to inspect baggage. These locks are commercially available, and packaging on the locks should indicate they may be opened by TSA officers. TSA has no position on the validity or effectiveness of these product as a security measure and will be forced to remove these products if necessary during the inspection.
