## Highlights

The Implementing Recommendations of the 9/11 Commission Act of 2007 requires the Transportation Security Administration (TSA) to implement a system to physically screen 100 percent of cargo on passenger aircraft by August 2010. To fulfill these requirements, the Department of Homeland Security's (DHS) TSA is developing the Certified Cargo Screening Program (CCSP), which would allow the screening of cargo to occur prior to placement on an aircraft. This testimony addresses four challenges TSA may face in developing a system to screen 100 percent of cargo: (1) deploying effective technologies; (2) changing TSA air cargo screening exemptions; (3) allocating compliance inspection resources to oversee CCSP participants; and (4) securing cargo transported from a foreign nation to the United States. GAO's comments are based on GAO products issued from October 2005 through February 2008, including selected updates conducted in July 2008.
