Which directive sets national continuity policy for the U.S. Government?

The directive that sets national continuity policy for the U.S. Government is HSPD-20, or Homeland Security Presidential Directive 20. This directive specifically outlines the importance of ensuring continuity of operations for federal agencies during emergencies, including natural disasters, terrorist attacks, and other crises that may disrupt governmental function.

HSPD-20 provides a framework for identifying critical functions and establishing plans to maintain operations despite adverse conditions. It underscores the necessity for resilience in government operations, ensuring that essential services keep running, which is vital for national security and public safety.

In contrast, the other options, while related to security and information management, do not set national continuity policy. PPD-21 focuses on critical infrastructure security and resilience; SP 800-37 pertains to risk management frameworks for information systems; and OMB Circular A-130 deals primarily with managing information resources within the executive branch. Although these directives contribute to broader governmental resilience and security strategies, they do not specifically implement the continuity policy mandated by HSPD-20.
