The EMR–ISAC works with the Department of Homeland Security's (DHS's) Cybersecurity and Infrastructure Security Agency and Office of Intelligence and Analysis to collect and share critical infrastructure protection and emerging threat information relevant to the ESS from federal, state, local, tribal, territorial and private sector partners. Information is published through DHS information sharing mechanisms, including:
