## Highlights

As part of its mission, the Department of Homeland Security (DHS), through its U.S. Customs and Border Protection (CBP) component, is to secure U.S borders against threats of terrorism; the smuggling of drugs, humans, and other contraband; and illegal migration. At the end of fiscal year 2010, DHS investments in border security had grown to $11.9 billion and included more than 40,000 personnel. To secure the border, DHS coordinates with federal, state, local, tribal, and Canadian partners. This testimony addresses DHS (1) capabilities to enforce security at or near the border, (2) interagency coordination and oversight of information sharing and enforcement efforts, and (3) management of technology programs. This testimony is based on related GAO work from 2007 to the present and selected updates made in February and March 2011. For the updates, GAO obtained information on CBP performance measures and interviewed relevant officials.
