Research on the Network Security Protection Model of the New Power System

In the process of promoting the construction of the new power system, in view of the current situation that the network structure of the power system is becoming increasingly complex and the network's closed nature is gradually being broken, this paper proposes a terminal network security protection model based on the zero-trust concept. Starting from six aspects: policy, isolation, identification, protection, detection, and response, this model realizes controlled and secure access to resources through the all-round closed-loop management of the users, hardware, software and behaviors of network entities. Through this model, not only has the protection ability of the new power system against network threats been significantly enhanced, but it also provides new ideas and practical references for the research and design of network security protection in future power systems.
