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.

  • Determination of a National Emergency Requiring Actions to Protect the Safety of Americans Using and Employed by the Transportation System

    As reflected in numerous determinations by the Executive Branch, including the President’s March 13, 2020 determination that the outbreak of Coronavirus Disease 2019 (COVID-19) constitutes a “national emergency” under the National Emergencies Act and the nationwide public health emergency declared by the Secretary of Health and Human Services on January 31, 2020, the COVID-19 pandemic continues to pose a threat to our health and security.

  • Travel Risk Assessment

    The DHS Office of Strategy, Policy, and Plans recently completed its evaluation and review of all currently travel restricted and 180-day warning countries.  Notably, this review included new recommendations to remove from travel restrictions certain countries that have demonstrated significant compliance improvement.

  • 2020 Biennial National Strategy for Transportation Security (NSTS)

    The 2020 National Strategy for Transportation Security (NSTS) report is a forward-looking, risk-based strategy designed to protect the Nation’s transportation systems from attack or disruption by terrorists or other hostile forces over the period spanning years 2020-2025.

  • Green Light Law

    In response to New York State implementing the Driver’s License Access and Privacy Act (Green Light Law), Acting Secretary Chad F. Wolf announced New York residents will no longer be eligible to apply for or renew their enrollment in certain Trusted Traveler Programs (TTP) like Global Entry. The law prohibits the Department of Motor Vehicles (DMV) from sharing information with U.S. Department of Homeland Security (DHS), preventing DHS from fully vetting New York residents.

  • Notices of Arrival Restrictions Due to Coronavirus

    To protect the American people from exposure to Coronavirus (COVID-19), Acting Secretary Chad F. Wolf issued instructions supplementing a decision issued on January 31, 2020 directing all flights from specified countries to be routed through designated U.S. airports where the government is focusing public health resources.

  • Report on Airports Used by Mahan Air

    Pursuant to the TSA Modernization Act (P.L. 115-254), signed into law on October 5, 2018, the report provides information on Mahan Air operations and U.S. security interests at international Last Point of Departure airports.

  • S&T Behavior Detection Visual Search Task Analysis Project Visual Search Battery Report

    Approximately 1.2 million people fly within the United States every day. To keep these passengers safe, the Transportation Security Administration (TSA) employs a multilayer security system to ensure that the traveling public and the nation’s transportation systems are protected. The Behavior Detection (BD) program serves an essential function in this multilayered security approach. Unique from other security capabilities within the TSA security system, the BD program, which was previously reserved for Behavior Detection Officers (BDOs) but is now comprised of Transportation Security Officers (TSOs) as well, trains officers to identify anomalous behaviors by observing passengers and comparing what they see to an established behavioral baseline. The goal of the program is to identify high-risk travelers and subject them to additional screening. This report describes the results of an empirical study that addressed these research goals and furthered DHS S&T’s understanding of the visual search process required for successful BD performance.

  • 2018 AEP

    Analytic deliverables from the 2018 cycle of the Analytic Exchange Program

  • DHS/TSA/PIA-049 TSA Office of Inspection Case Management

    The Transportation Security Administration (TSA) Office of Inspection (OOI) conducts covert testing of security screening operations; inspects TSA operations at airports, field offices, and other transportation entities; and investigates employee misconduct and program fraud, and violations of transportation security requirements. OOI’s hotline referral and case management systems maintain Personally Identifiable Information (PII): (1) from individuals submitting information to OOI; and (2) on individuals designated as witnesses, victims, complainants, or subjects of an investigation.

  • 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.
