摘要:Currently, there are concerns about cyber attacks and hacking on the national backbone, and the statelike North Korea is actively developing the interim version. Especially in the recent military, the tacticalnetwork which is divided physically and logically for various purposes is trying to implement the conceptof integrated operation for securing the interoperability. In this integrated cyber tactical network, the cyberthreat of North Korea changed the battlefield of cyber tactical network And is carrying out a new type ofattack and defense operation that performs cyber operations. However, it is difficult to carry out the versionbetween effective combat damage evaluation and effective cyber-operation and active defense concept.Therefore, this study suggests M-DCIA (Military - Data, Confidentiality, Integrity, Availability) for effectivecyber operations. This is an index model that can effectively analyze the damage situation through theanalysis of the limited damage phenomenon (scenario) in the military cyber operations and explains thatthis model is effective.
