Marines with 8th Communications Battalion, II Marine Expeditionary Force Information Group attend the activation of command ceremony for the Defensive Cyberspace Operations Internal Defense Measures (DCO-IDM) Company on Camp Lejeune, N.C., July 16, 2018. In order to address the increasing cyberspace threat to the Marine Air Ground Task Force the DCO-IDM Company will perform a variety of capabilities which include mission assurance actions, actively hunting for advanced persistent threats that evade routine security measures. The company will dynamically reestablish, re-secure, reroute, reconstitute, or isolate degraded or compromised local networks in response to attack, exploitation, intrusion, or effects of malware on the Department of Defense Internal Network or other assets they are directed to defend. The company will support active cyber defense to proactively defend against anticipated attacks in cyberspace. Capt. Ronald Ellsworth took command of DCO-IDM Company as the company commander.
