Maritime Security: Progress and Challenges in Implementing Maritime Cargo Security Programs, Statement of Jennifer A. Grover, Director Homeland Security and Justice, Testimony Before the Subcommittees on Coast Guard and Maritime Transportation and Border and Maritime Security, Committees on Transportation and Infrastructure and Homeland Security, House of Representatives [open pdf - 2MB]
"The U.S. economy is dependent on the expeditious flow of millions of tons of cargo each day through the global supply chain--the flow of goods from manufacturers to retailers. Criminal or terrorist attacks using cargo shipments can cause disruptions to the supply chain and can limit global economic growth and productivity. Within DHS, CBP has responsibility for administering maritime cargo security measures and reducing the vulnerabilities associated with the supply chain. CBP has developed a layered security strategy that focuses its limited resources on targeting and examining high-risk cargo shipments that could pose a risk while allowing other cargo shipments to proceed without unduly disrupting commerce arriving in the United States. This statement discusses the progress and challenges associated with CBP's implementation of initiatives and programs responsible for enhancing the security of the global supply chain. The statement is based on reports and testimonies GAO issued from April 2008 through January 2015 related to maritime cargo security--with selected updates on how DHS has responded to GAO's prior recommendations. […] In prior reports, GAO has made recommendations to DHS to strengthen various maritime cargo security programs. DHS generally concurred with the recommendations and has taken actions, or has actions under way, to address many of these recommendations."
