Recently, only trusted functionality has been emphasized due to the nature of the weapon system, which is a closed network. We are responding to new cyber warfare threats by monitoring cyber warfare threats by establishing a security control system for weapons systems that are closed networks centered on the United States and Israel. Therefore, in this study, the security control monitoring method that minimizes the load through the layered weapon system gateway by analyzing the technology of the domestic and foreign weapon system security control system, the weapon system device forgery, change, update method, and the detection of new cyber warfare threats through the use of artificial intelligence method was proposed.
