Personnel Security and Internal Control at TSA’s Legacy Transportation Threat Assessment and Credentialing Office

The Department of Homeland Security’s (DHS) Transportation Security Administration (TSA) Transportation Threat Assessment and Credentialing Office was established as the lead for conducting security threat assessments and credentialing initiatives for domestic passengers on public and commercial modes of transportation, transportation industry workers, and individuals seeking access to critical infrastructure. Two programs, the Secure Flight Operations Center and the Security Threat Assessment Operations Adjudication Center, were established to conduct case-specific adjudications of potential threats to transportation security. In 2010, TSA initiated an administration-wide restructuring that includes reviewing all personnel position descriptions and realigning Transportation Threat Assessment and credentialing Office functions under other TSA offices.
