In 2016, the U.S. Department of Homeland Security DHS, Office of Policy Strategy, Plans, Analysis, and Risk SPAR, asked the RAND National Defense Research Institute NDRI to design and implement a homeland security national risk assessment to help inform DHS strategic planning by identifying and characterizing natural hazards and threats to the nation. This assessment can be used by DHS to assist in identifying the greatest risks to homeland security and to support prioritization of DHS mission elements. This report responds to SPARs request. It describes the risk assessment methodology developed by the RAND Corporation and presents summary sheets of threats and hazards intended to inform discussion of DHS risk management priorities. The methodology is also designed to address important critiques made by the U.S. Government Accountability Office GAO in its assessments of the 2010 and 2014 Quadrennial Homeland Security Reviews QHSRs. To address the GAO critiques, the approach described in this report describes a set of threats and hazards that is strategically relevant and does so in a consistent way. Furthermore, the process for selecting and characterizing the hazards uses a methodology that is repeatable and transparent.
