The command control system, like the human brain and nervous system, is a linker that connects the Precision Guided Missile(PGR) in information surveillance and reconnaissance (ISR) and is the center of combat power. In establishing the future command and control system, the ROK military should consider not only technical but also institutional issues. The US Department of Defense establishes security policies, refines them, and organizes them into architectural documents prior to the development of the command and control system. This study examines the security architecture applied to the US military command control system and analyzes the current ROK military-related policies (regulations) to identify security requirements for the future control system. By grouping the identified security requirements, this study identifies and presents field-specific enhancements to existing security regulations.

Launch control system controls the sequence for launching missile in weapon systems. This system have to generate the engagement plan, input information and launch the missile in timeliness requirement. Such a system may fail to operate correctly either due to errors in hardware and software or due to violation of timing constraints. We presented fault-tolerant ethernet for embedded real-time system like launch control system. This approach is designed to handle network faults using dual commercial-off-the-shelf(COTS) network devices. To support fault-tolerant ethernet each node is composed dual channel ethernet and designed the communication middleware for network fault detect and recovery. Especially for time-critical system, the middleware is being developed to achieve that no point of network failure shall take down or cause loss of communication to network nodes.
