U.S. Cyber Command (USCYBERCOM) fuses the Defense Department's full spectrum of cyberspace operations and plans, coordinates, integrates, synchronizes and conducts activities to lead day-to-day defense and protection of DoD information networks; coordinates DoD operations providing support to military missions; directs the operation and defense of specified DoD information networks; and prepares to conduct (and when directed, conducts) full-spectrum military cyberspace operations. The command is charged with pulling together existing cyberspace resources, creating synergy that does not currently exist, and synchronizing warfighting effects to defend the information security environment.

USCYBERCOM centralizes command of cyberspace operations, strengthens DoD cyberspace capabilities, and integrates and bolsters DoD's cyber expertise. USCYBERCOM improves DoD's capability to ensure resilient, reliable information and communications networks, counters cyberspace threats, and assures access to cyberspace.

USCYBERCOM's efforts support the armed services' ability to confidently conduct high-tempo, effective operations, as well as protect command and control systems and the cyberspace infrastructure supporting weapons system platforms from disruptions, intrusions and attacks.
