The Mission Centric Network Defense System (MCNDS) is a deployable network defense system that monitors network activities, generates and maintains situational awareness of operational activities, and uses this joint situational awareness of networked and operational activities to predict the mission impact of alterations and disruptions of networked resources. The MCNDS uses its predictive capability to rank information operation (IO) courses-of-action (COAs) and interpret network alarms and intrusion detections in terms of expected operational mission impact.

An efficient hardware cache manager controls the top-of-stack data underflow/overflow. A processor chip includes a processor, a stack buffer and the invented cache management hardware. The processor chip communicates with a remove overflow stack through an address/data bus. The cache management hardware efficiently manages overflow and underflow to and from the processor chip in such a manner less than 1% of the processor's time is spent managing the stack cache.
