Advisory memorandum on identification of essential critical infrastructure workers during covid-19 response / The Cybersecurity and Infrastructure Security Agency (CISA) executes the Secretary of Homeland Security’s authorities to secure critical infrastructure. Consistent with these authorities, CISA has developed, in collaboration with other federal agencies, State and local governments, and the private sector, an “Essential Critical Infrastructure Workforce” advisory list. This list is intended to help State, local, tribal and territorial officials as they work to protect their communities, while ensuring continuity of functions critical to public health and safety, as well as economic and national security. Decisions informed by this list should also take into consideration additional public health considerations based on the specific COVID-19-related concerns of particular jurisdictions.
