The Cybersecurity and Infrastructure Security Agency (CISA) launches a nationwide initiative, Critical Infrastructure (CI) Fortify: Strengthening Resilience Across Critical Infrastructure, as a multi-year effort designed to improve the agency’s ability to anticipate, prioritize, and manage national-level risks to industrial control systems (ICS). The initiative, which includes the HPH Sector, focuses on collaboration with critical infrastructure owners and operators to build security capabilities that enable stakeholders to better protect their operations from cyber threats. The intended audience for the effort is as the entire ICS community, including government entities, private sector organizations, and other partners with an interest in ICS security. Supporting materials, such as fact sheets, provide summarized guidance derived from the broader strategy to help stakeholders understand and implement security practices.
