Critical infrastructure are the assets, systems, and networks, whether physical or virtual, so vital to the United States that their incapacitation or destruction would have a debilitating effect on security, national economic security, national public health or safety, or any combination thereof.
There are 16 critical infrastructure sectors as outlined in Presidential Policy Directive 21 (PPD-21): Critical Infrastructure Security and Resilience. Additional information on current critical infrastructure strategy and sector-specific agencies can be found on the Department of Homeland Security- Cybersecurity & Infrastructure Security Agency (CISA) website.
The graphic below shows the 16 critical infrastructure sectors and the Infragard- Evergreen Chapter Sector Chief (if any). If you are knowledgeable about a given sector and interested in fostering collaboration in your area, please consider serving as a Sector Chief.
