Since its inception in 2001, TSA has developed and implemented a variety of programs and procedures to secure commercial aviation and surface modes of transportation. Other DHS components, federal agencies, state and local governments, and the private sector also play a role in transportation security. GAO has examined (1) the progress TSA and other DHS components have made in securing the nation's aviation and surface transportation systems, and the challenges that remain, and (2) crosscutting issues that have impeded TSA's efforts in strengthening security. This testimony is based on GAO reports and testimonies issued from February 2004 to February 2008 and ongoing work regarding the security of the nation's aviation and surface transportation systems, as well as selected updates to this work conducted in April 2008. To conduct this work, GAO reviewed documents related to TSA security efforts and interviewed TSA and transportation industry officials. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-08-651T/html/GAOREPORTS-GAO-08-651T.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-08-651T/pdf/GAOREPORTS-GAO-08-651T.pdf GAO-08-651T https://www.govinfo.gov/app/details/GAOREPORTS-GAO-08-651T Testimony GAO-08-651T; Transportation Security: Efforts to Strengthen Aviation and Surface Transportation Security Continue to Progress, but More Work Remains; Air transportation Airport security Aviation Aviation security Cargo screening Commercial aviation Ground transportation Passenger screening Passengers Performance measures Program evaluation Program management Risk assessment Risk factors Risk management Security assessments Security regulations Security threats Standards Strategic planning Systems analysis Technology assessment Transportation Transportation policies Transportation safety Transportation security Program goals or objectives Program implementation Security operations Volume 115 Page 597 115 Stat. 597 Volume 121 Page 405-08 Volume 121 Page 1844 121 Stat. 405-08 121 Stat. 1844 Public Law 107-71 Public Law 110-53 Public Law 110-161
