"At the end of fiscal year 2004, DHS had about 28,100 personnel assigned to patrol U.S. land borders and inspect travelers at air, land, and sea POEs [Ports of Entry], with a total security cost of about $5.9 billion. At the end of fiscal year 2011, DHS had about 41,400 personnel assigned to air, land, and sea POEs and along the borders, with a total security cost of about $11.8 billion. DHS has reported that these resources have contributed to stronger enforcement efforts on the border. However, challenges remain to secure the border. In recent years, GAO [Government Accountability Office] has reported on a variety of DHS border security programs and operations. As requested, this statement addresses some of the key issues and recommendations GAO has made in the following areas: (1) DHS's efforts to secure the border at and between POEs; (2) DHS interagency coordination and oversight of border security information sharing and enforcement efforts; and (3) DHS management of infrastructure, technology, and other assets used to secure the border. This statement is based on prior products GAO issued from January 2008 through March 2013, along with selected updates conducted in April 2013. For selected updates, GAO reviewed DHS information on actions it has taken to address prior GAO recommendations. […] In prior reports, GAO made recommendations to DHS to strengthen its border security programs and efforts. DHS generally concurred and has taken actions, or has actions planned or underway to address them."
