"The United States continues to face a range of evolving threats, such as the 2010 attempted attack on the nation's air cargo system, that underscore why homeland security planning efforts are crucial to the security of the nation. The Implementing Recommendations of the 9/11 Commission Act of 2007 required the Department of Homeland Security (DHS) to provide a comprehensive examination of the U.S. homeland security strategy every 4 years. In response, DHS issued its first Quadrennial Homeland Security Review (QHSR) report in February 2010 and a Bottom-Up Review (BUR) report in July 2010, to identify initiatives to implement the QHSR. As requested, this report addresses the extent to which DHS (1) consulted with stakeholders in developing the QHSR, (2) conducted a national risk assessment, and (3) developed priorities, plans, monitoring mechanisms, and performance measures for implementing the QHSR and BUR initiatives. GAO analyzed relevant statutes and DHS documents on the QHSR and BUR processes and, in response to a request for comments on the processes, received comments from 63 of the 85 federal and nonfederal stakeholders it contacted. Their responses are not generalizable, but provided perspectives on the processes. "
