Transportation Security

TSA employs a risk-based strategy to secure U.S. transportation systems, working closely with transportation sector stakeholders, as well as the partners in the law enforcement and intelligence community.

  • DHS/TSA/PIA-048 Insider Threat Unit Database

    The Transportation Security Administration (TSA) protects the Nation’s transportation systems to ensure freedom of movement for people and commerce. In support of this mission, the TSA Insider Threat Unit seeks to deter, detect, and mitigate insider threats from causing harm to the transportation domain. For purposes of the TSA Insider Threat Unit, “insiders” are, or present themselves to be, current or former transportation sector workers (including both TSA and private sector personnel) and individuals employed or otherwise engaged in providing services requiring authorized access to transportation facilities, assets, or infrastructure. Investigative files will be maintained in a database maintained by the Insider Threat Unit.

  • DHS/TSA/PIA-046 Travel Document Checker Automation Using Facial Identification

    The Transportation Security Administration (TSA) will enhance the identity verification of passengers by using facial verification technology at airports. In a previous proof of concept, TSA used a Credential Authentication Technology (CAT) device equipped with a camera (CAT-C) to validate that the identity document presented by the passenger was authentic and to compare the passenger’s live facial image against the image from the passenger’s identity document. Building on its previous work, TSA will now network the CAT-C to the TSA Secure Flight system so that passenger boarding pass information can be passed from Secure Flight to the CAT-C. This will provide improved real-time boarding pass instructions with improved identity matching and reduced physical handling of travel documents to limit unnecessary exposure, such as during the Coronavirus (COVID-19) pandemic.

  • September 2017 Jones Act Waivers

    On September 8, 2017 and in recognition of the severity of Hurricanes Harvey and Irma, Department of Homeland Security Acting Secretary Elaine Duke approved a waiver of the federal Jones Act.  This waiver will ensure that over the next week, all options are available to distribute fuel to states and territories impacted by Hurricanes Harvey and Irma, both historic storms. The waiver will be in effect for seven days after signature and is specifically tailored to transportation of refined products in hurricane-affected areas.

  • Maryland Three (MD-3) Airports

    TSA conducts security threat assessments and fingerprint-based Criminal History Records Checks (CHRCs) on pilots who operate aircraft and apply for privileges to fly to or from the three General Aviation airports in the Washington, D.C. restricted flight zones (Potomac Airfield, Washington Executive/Hyde Field, and College Park Airport), otherwise known as the Maryland Three (MD-3) program, and for the Airport Security Coordinator (ASC) at a MD-3 airport.

  • Screening of Passengers by Observation Techniques (SPOT) Program

    The Screening of Passengers by Observation Techniques (SPOT) program is a behavior observation and analysis program designed to provide the Transportation Security Administration (TSA) Behavior Detection Officers (BDOs) with a means of identifying persons who pose or may pose potential transportation security risks by focusing on behaviors indicative of high levels of stress, fear, or deception. The SPOT program is a derivative of other behavioral analysis programs that have been successfully employed by law enforcement and security personnel both in the U.S. and around the world. This PIA update reflects that TSA will pilot the use of BDOs as part of the security checkpoint process, by incorporating BDO interaction with passengers.

  • TSA Canine Website System (CWS)

    The Canine Website System (CWS) is a web-based system administered by the Transportation Security Administration (TSA) National Explosives Detection Canine Team Program (NEDCTP) to coordinate operations. CWS is a privacy sensitive system because it collects personally identifiable information (PII) from program participants to facilitate training, foster communication, and to perform administrative functions. In accordance with the Section 208 of the E-Government Act of 2002, TSA is updating CWS’s Privacy Impact Assessment (PIA) from January 2012 to reflect that it also collects PII from members of the public interested in adopting NEDCTP canines.

  • Large Aircraft Security Program (LASP)

    TSA has issued a Notice of Proposed Rule Making (NPRM) which would establish a security program called the, Aircraft Security Program (LASP) for the large aircraft operators and will require security threat assessments (STAs) for various categories of individuals Large. This Privacy Impact Assessment (PIA) is being conducted in conjunction with a the NPRM. The PIA will be updated to reflect any changes made prior to publication of the Final Rule. No information will be collected by TSA prior to publication of the Final Rule.

  • e-Law Enforcement Officer Logbook Program (e-Logbook)

    August 31, 2009. The e-Logbook is as an electronic means of logging and confirming the identity of Law Enforcement Officers with a need to Fly Armed (hereinafter LEOFA).
