The Marine Corps Network Operations and Security Center (MCNOSC) is the nerve center for the central operational direction and configuration management of the Marine Corps enterprise network. It is co-located with the Marine Corps forces computer network defense, the component to the joint task force for computer network operations, and the Marine Corps computer incident response team. These relationships provide a strong framework for integrated network management and defense.
It provides engineering functions related to the effective integration and employment of hardware, software and computer network practices that comprise the Marine Corps Enterprise Network (MCEN). MCNOSC engineers, develops, and tailors the Marine Corps' network defense infrastructure, and its engineering efforts have resulted in key innovations that have become recommended practice in adjacent DOD network operations commands.
