2014 Quadrennial Homeland Security Review: Evolution of a Strategic Review [Updated September 9, 2019] [open pdf - 400KB]
From the Overview: "In June 2014, the Department of Homeland Security (DHS) reported the second iteration of the Quadrennial Homeland Security Review (QHSR) to Congress. DHS states that the QHSR is a 'comprehensive examination of the homeland security strategy of the Nation, including recommendations regarding the long-term strategy and priorities of the Nation for homeland security.' The QHSR is a process in which DHS examines the nation's homeland security strategy; the report delivered to Congress provides an explanation of this process. Neither the review process nor the report to Congress is the strategy, instead the 2014 QHSR (both the process and the report) are part of the constant reevaluation of the nation's homeland security and part of the process by which the combined National and Homeland Security Staff develops the next iteration of the national security strategy."
