Federal Cybersecurity
FCEB
Federal Civilian Executive Branch, the set of executive branch agencies excluding the Department of Defense and the Intelligence Community elements. The FCEB scope is the regulatory boundary for CISA Binding Operational Directives, Emergency Directives, the Continuous Diagnostics and Mitigation program, and most OMB cybersecurity memoranda including M-22-09. Agencies in the FCEB include the cabinet-level departments other than DoD, plus independent agencies like EPA, NASA, and SSA. DoD, the Intelligence Community, and the legislative and judicial branches operate under separate authorities and are not subject to CISA directives.
