Who handles information sharing in critical infrastructure?

CISA, or the Cybersecurity and Infrastructure Security Agency, is the primary agency responsible for information sharing in critical infrastructure. It was established to secure the nation's critical infrastructure from physical and cyber threats. CISA facilitates collaboration and information sharing between federal, state, local, tribal, and territorial government entities, as well as private sector partners, enhancing the overall resilience of critical services.

CISA's role includes the development of programs and initiatives aimed at improving the security of systems that support essential services, such as energy, water, transportation, and communications. By fostering communication and sharing of best practices and threat intelligence, CISA plays a crucial role in ensuring a coordinated response to incidents that may impact critical infrastructure.

Other agencies mentioned may have relevant roles or touchpoints in infrastructure security, but CISA uniquely stands out as the lead agency focused explicitly on information sharing related to critical infrastructure.
