PPD-21

The Department of Homeland Security leads the federal government’s efforts to secure our nation’s critical infrastructure by working with owners and operators to prepare for, prevent, mitigate, and respond to threats. To address threats to our nation from cyber-attacks, natural disasters, or the actions of others that could disrupt our power, water, communications and other critical systems, the President issued PPD-21 (Executive Order on Improving Critical Infrastructure Cybersecurity and Presidential Policy Directive on Critical Infrastructure Security and Resilience).

The policies within PPD-21 link both cyber and physical security information sharing between the National Cyber Security Communications and Integrations Center (NCCIC) and the National Infrastructure Coordinating Center (NICC) to enhance the efficiency and effectiveness of the U.S. government’s work to secure critical infrastructure and make it more resilient. These centers, along with an integrated analysis function, build situational awareness across critical infrastructure sectors based on partner input, and provide information with greater depth, breadth, and context than information from any individual partner or sector.

PPD-21 highlights the importance of these centers and the multidirectional information sharing that enables them to build true situational awareness. “The success of these national centers, including the integration and analysis function, is dependent on the quality and timeliness of the information and intelligence they receive from the Sector-Specific Agencies (SSAs) and other Federal departments and agencies, as well as from critical infrastructure owners and operators and State, local, tribal, and territorial (SLTT) entities.” Critical infrastructure owners and operators receive information directly from the centers, but also frequently receive information through their respective SSAs, or other parties such as regional consortia, ISACs, fusion centers, etc.

Communications Sector

PPD-21 identifies the Communications Sector as critical because it provides an “enabling function” across all critical infrastructure sectors. The sector has evolved from predominantly a provider of voice services into a diverse, competitive, and interconnected industry using terrestrial, satellite, and wireless transmission systems. The Communications Sector-Specific Plan details how the National Infrastructure Protection Plan risk management framework is implemented.

Dams Sector

The Dams Sector contains a combination of government and private-sector owned assets. During incidents, the sector interacts directly with the owners of the dams to coordinate resources and public protection. Support for geospatial requirements is coordinated through the NICC by the SSA. In addition, the owners/operators utilize their internal geospatial resources, providing relevant products to the SSA and their partners.

Energy Sector

Presidential Policy Directive 21 identifies the Energy Sector as uniquely critical because it provides an “enabling function” across all critical infrastructure sectors. More than 80 percent of the country's energy infrastructure is owned by the private sector, supplying fuels to the transportation industry, electricity to households and businesses, and other sources of energy that are integral to growth and production across the nation. The Energy Sector-Specific Plan details how the National Infrastructure Protection Plan risk management framework is implemented.

Government Facilities Sector

The Government Facilities Sector includes a wide variety of buildings, located in the United States and overseas, that are owned or leased by federal, state, local, and tribal governments. Many government facilities are open to the public for business activities, commercial transactions, or recreational activities while others that are not open to the public contain highly sensitive information, materials, processes, and equipment.

Healthcare and Health Sector

Operating in all U.S. states, territories, and tribal areas, the sector plays a significant role in response and recovery across all other sectors in the event of a natural or manmade disaster. It protects all sectors of the economy from hazards such as terrorism and infectious disease outbreaks. Because the vast majority of the sector's assets are privately owned and operated, collaboration and information sharing between the public and private sectors is essential to increasing resilience of the nation's Healthcare and Public Health critical infrastructure. The Healthcare and Public Health Sector-Specific Plan details how the National Infrastructure Protection Plan risk management framework is implemented.
