Research on Cross-Domain Attack Defense and Endogenous Security Mechanism in Power Dispatching Systems Based on Microservices

As power dispatching systems evolve toward microservice architectures, containerized modules for scheduling, trading, data collection, and auditing enhance flexibility but also expand the attack surface, exposing risks such as link hijacking, container escape, and cross-domain privilege escalation. This paper presents an endogenous security framework that integrates SM2/SM4-based encrypted communication, zero-Trust access control, and runtime anomaly detection. Mutual authentication ensures secure links, while OPA-UEBA enforces fine-grained authorization, and eBPF with IsolationForest enables real-Time threat detection. Experiments demonstrate over 99% link integrity, 97% node trust, 98% access accuracy, and sub-150 ms latency, offering a practical model for resilient power dispatching security.
