Overview
The Secretary of Defense recognized the significance of the cyberspace domain to national security, and directed the establishment of CYBERCOM as a sub-unified command under STRATCOM. CYBERCOM's primary objective is to integrate the cyberspace operations capabilities of the services and agencies in support of the National Strategy to Secure Cyberspace (NSSC).

In response, the Marine Corps established MARFORCYBER in October 2009 (this was complemented by the standing up of the Fleet Cyber Command, U.S. Army Cyber Command (ARCYBER), and Air Force Cyberspace Command (AFCYBER). MARFORCYBER's mission, in addition to its standard service component responsibilities, is to: plan, coordinate, integrate, synchronize, and direct the Corps' full spectrum of cyberspace operations. This includes Department of Defense (DoD) Information Network (DoDIN) operations, Defensive Cyber Operations (DCO), and planning and, when required, executing Offensive Cyberspace Operations (OCO). These operations support MAGTF, Joint and combined cyberspace requirements that enable freedom of action across all warfighting domains and deny the same to adversarial forces.
