Aviation Security: TSA Could Strengthen Its Insider Threat Program by Developing a Strategic Plan and Performance Goals, Report to Congressional Requesters [open pdf - 3MB]
From the Document: "Aviation workers using their access privileges to exploit vulnerabilities and potentially cause harm at the nation's airports is known as an 'insider threat.' TSA [Transportation Security Administration], airport operators, and air carriers share the responsibility to mitigate all insider threats at airports. In October 2019, TSA estimated there are about 1.8 million aviation workers at the nation's airports. GAO [Government Accountability Office] was asked to review TSA's and aviation stakeholders' efforts to mitigate insider threats at airports. This report (1) discusses the efforts that TSA, airport operators, and air carriers have taken to help mitigate insider threats at airports and (2) evaluates the extent to which TSA's Insider Threat Program is guided by a strategic plan and has performance goals. GAO reviewed TSA guidance; analyzed TSA data from a questionnaire sent to a representative sample of airport operators; and obtained information from TSA officials, officials from selected larger U.S.-based air carriers, and a nongeneralizable sample of seven airport operators, selected, in part, based on the number of aircraft takeoffs and landings."
