The Risk-Mitigation Value of the Transportation Worker Identification Credential: A Comprehensive Security Assessment of the TWIC Program

The U.S. Department of Homeland Security (DHS) commissioned the Homeland Security Operational Analysis Center (HSOAC) to conduct this congressionally mandated study to address the requirements of Public Law 114-278, Section 1(b), Comprehensive Security Assessment of the Transportation Security Card Program. The Transportation Worker Identification Credential (TWIC) program includes a security threat assessment to determine whether someone poses a national security, transportation security, or terrorism threat. It also provides for a card credential and requirements for its use at maritime facilities that are regulated by the Maritime Transportation Security Act. In this report HSOAC focuses on TWIC's risk-mitigation value through data collected from DHS, the Transportation Security Administration, the U.S. Coast Guard, a literature review, port visits, and interviews with facility security officers and other industry representatives. Topics covered in this report include: how TWIC fits into access control programs, electronic biometric readers, terrorism threat and security risks at maritime facilities, effectiveness of the security threat assessment (STA) process, TWIC limitations, cost benefits of the TWIC-reader rule, TWIC alternatives, and previous Government Accountability Office (GAO) and Office of Inspector General (OIG) concerns.
