Some of the vulnerable areas cited in the aforementioned report, including border and cargo security, have been the subject of recent scrutiny by the U.S. General Accounting Office (GAO). GAO auditors, for instance, recently checked on the status of the US-VISIT (United States Visitor and Immigrant Status Indicator Technology) program, finding that it is "inherently risky, both because of the type of program it is and because of the way it is being managed." Specifically, US-VISIT is inherently risky because it is responsible for a critical, multifaceted mission; has a large and complex scope; must meet a demanding implementation schedule; and entails enormous cost. Risks relating to management include initial reliance on integrating existing systems that have problems. In testimony on cargo inspection, the GAO's Richard M. Stana noted that the Department of Homeland Security's U.S. Customs and Border Protection (CBP) fails to incorporate key elements of a risk management framework in its approach to risks posed by oceangoing cargo containers. CBP, Stana told the Subcommittee on Oversight and Investigations, House Committee on Energy and Commerce, hasn't determined the level of risk for cargo or the responses necessary to mitigate that risk. Moreover, CBP hasn't subjected its method of selecting and inspecting cargo containers to external peer review or testing, he said.
