Research on Power System Security Protection Technology Based on Active Defense

This article proposes a security protection technology based on active dynamic defense technology. Solved unknown threats that traditional rule detection methods cannot detect, effectively resisting purposeless virus spread such as worms; Isolate new unknown viruses, Trojans, and other attack threats; Strengthen terminal protection, effectively solve east-west horizontal penetration attacks in the internal network, and enhance the adversarial capabilities of the internal network. Propose modeling user behavior habits based on machine learning algorithms. By using historical behavior models, abnormal user behavior can be detected in real-time, network danger can be perceived, and proactive changes in network defense strategies can be taken to increase the difficulty of attackers. To achieve comprehensive and effective defense, identification, and localization of network attack behaviors, including APT attacks.
