Research on the Security Defense Architecture of the Closed-source Power Industrial Control System

In order to ensure the power industrial control system security control in the “unification” and “dynamics”, this paper has designed 3d spatial coordinate axes including safety protection technology dimension (X axis-T), safety emergency response dimension (Y axis-E), comprehensive safety management dimension (Z axis-M) and one dimensional security defense scenarios coordinate axis (T axis-A), which makes up four dimensional space-time stereoscopic defense system architecture. On the one hand, in the technical dimension, the real-time monitoring of the system itself, the security techniques and defensive measures can be strengthened, so as to guarantee the comprehensive and effective implementation of the security techniques and management measures dynamically and in a closed loop, thus to ensure the robustness of the protection system architecture. On the other hand, to adapt to the power industrial control system of the overall “cloud + network + terminal” structure, this paper forms systematic power defense architecture in power industrial control system by multi-chain protection compromised technology and system and different business scenarios “cloud + network + terminal” linkage and synergy between multi-level security defense line. Finally, this study provides effective guidance for technical selection, deployment and application of defense model.
