The Strategic National Risk Assessment (SNRA) was executed by the DHS Office of Risk Management and Analysis in support of Presidential Policy Directive 8 (PPD-8), which calls for the creation of a National Preparedness Goal, a National Preparedness System, and a National Preparedness Report. Specifically, national preparedness is to be based on core capabilities that support "strengthening the security and resilience of the United States through systematic preparation for the threats that pose the greatest risk to the security of the Nation, including acts of terrorism, cyber attacks, pandemics, and catastrophic natural disasters."
As part of the effort to develop the National Preparedness Goal and identify core capabilities, the Secretary of Homeland Security led an effort to conduct a strategic national risk assessment to help identify the types of incidents that pose the greatest threat to the Nation's homeland security. The assessment was used:
- To identify high risk factors that supported development of the core capabilities and capability targets in the National Preparedness Goal;
- To support the development of collaborative thinking about strategic needs across prevention, protection, mitigation, response, and recovery requirements, and;
- To promote the ability for all levels of Government to share common understanding and awareness of National threats and hazards and resulting risks so that they are ready to act and can do so independently but collaboratively.
