By Cybersecurity and Infrastructure Security Agency:

From the Introduction: "Infrastructure is the backbone of our communities, providing not only critical services (such as water, transportation, electricity, and communications), but also the means for health, safety, and economic growth. These systems often extend beyond our communities providing service to entire regions and contributing to the delivery of National Critical Functions [hyperlink]. Given the vital importance of infrastructure to our social and economic well-being, it is imperative we ensure our networks are strong, secure, and resilient. [...] The Cybersecurity and Infrastructure Security Agency (CISA) developed the Infrastructure Resilience Planning Framework (IRPF) to provide an approach for localities, regions, and the private sector to work together to plan for the security and resilience of critical infrastructure services in the face of multiple threats and changes. The primary audience for the IRPF is state, local, tribal, and territorial governments and associated regional organizations; however, the IRPF can be flexibly used by any organization seeking to enhance their resilience planning. It provides resources for integrating critical infrastructure into planning as well as a framework for working regionally and across systems and jurisdictions."
