Presidential Policy Directive 21 is also known as the Presidential Policy Directive on Critical Infrastructure Security and Resilience. This directive coordinates and unifies the national effort to strengthen and maintain critical infrastructure. The Federal approach to strengthening critical infrastructure is composed of three strategic imperatives:

  1. Refine and clarify functional relationships across the Federal Government to advance the national unity of effort to strengthen critical infrastructure security and resilience.
  2. Enable effective information exchange by identifying baseline data and systems requirements for the Federal Government.
  3. Implement an integration and analysis function to inform planning and operations decisions regarding critical infrastructure.

The endeavor of PPD 21 is a shared responsibility among Federal, state, local, tribal, and territorial entities; public and private owners; and the operators of critical infrastructure. The continuity of the national infrastructure is a high priority of the Federal Government and this is supported through effective partnerships across all of these sectors. Effective engagement from Sector-Specific Agencies, as well as the support capabilities of other agencies, are necessary to maintain these strong partnerships.

U.S. DOE is identified as the Sector-Specific Agency responsible for the Energy Sector in this directive. CESER’s role within PPD 21 is to work with energy infrastructure owners and operators to take proactive steps that manage risk and strengthen the national energy security infrastructure. CESER will coordinate with industry stakeholders to reduce vulnerabilities, disrupt threats, and improve response and recovery. CESER also will work alongside the U.S. Nuclear Regulatory Commission to strengthen the security and resilience of the national critical infrastructure.
