JFHQ-DODIN is the U.S. Cyber Command component responsible for leading DoD’s unified force approach to network operations, security, and defense across the Department of Defense Information Network, commonly known as the DODIN. This global command and control responsibility works to ensure mission assurance and bolster DoD’s competitive advantage. Its mission covers a broad range of activities including proactive, threat-informed steps to reduce cyber risk across the DODIN, and leading response to attacks against the DODIN to ensure network operations remain agile and resilient. The Command’s unique directive authority for cyberspace operations (DACO) enables it globally integrate command and control for DODIN Operations and Defensive Cyberspace Operations-Internal Defensive Measures (DCO-IDM) across 45 DODIN areas of operations (DAOs) that includes Combatant Commands, Services, and DoD Agencies and Field Activities. Daily interactions with the DAOs address threats and vulnerabilities to the DODIN by sharing cyber operations information and cyber intelligence, validating status of directed cyberspace actions, and shaping defensive cyber priorities for unclassified and classified networks, cyber enabled devices, and systems connected to the DODIN.
