Network Operations Security Center

Overview
A Network Operations Security Center (NOSC) provides military commanders with real-time operational network intrusion detection and perimeter defense capabilities, as well as theater-level network management and fault resolution activities. This dedicated first-line of defense is employed at the commander’s direction to defend information networks both in-theater and in-garrison. Equipped with advanced systems, a NOSC can deploy automated equipment and augmentation forces in theater, as needed, to perform CND and information assurance operations. NOSCs provide data fusion, assessment, and decision support.
