An Emergency Directive (ED) is an urgent order issued by the Cybersecurity and Infrastructure Security Agency (CISA) to federal agencies in the United States. These directives are legally binding and require immediate action to address significant cybersecurity threats, vulnerabilities, or incidents that could jeopardize government information systems. Emergency Directives are used in situations where rapid response is necessary to prevent or mitigate substantial harm to federal networks and data. Agencies must comply within specified timeframes and report their actions back to CISA. EDs play a critical role in the federal government’s incident response and risk management strategy, ensuring swift and coordinated action against emerging cyber threats.
