Research on Network Security Active Defense System Oriented to Electric Power Monitoring System

The safety control and production management of the electric power system are highly dependent on network communication between all levels. The security problems of the network always threaten the stable operation of the power grid. Combined with the analysis of the network security demands of the electric power monitoring system, an active defense system framework design is proposed, and a complete set of defense methods is given from the aspects of the host, the security and the network equipment. The system adopts multi-layer architecture and functional modular design. It integrates modules such as data collection, threat analysis and identification, active defense, active defense strategy library, and public service. The structure of each functional module is independent of each other, which facilitates independent deployment or unit testing.
