Research On Information Security Situation Of Wireless Public Network Based On Data Mining Algorithm

The wireless public network is a common networking method in power service communication.This paper combines the research situation of the Southern Power Grid "Wireless Network Access Security Scheme for Distribution Network"undertaken by the research group,and studies the design of the network security situational awareness platform architecture for the wireless public network in the distribution network.Research is carried out in the fields of data security partitioning and channel attack detection.According to the isolation authentication requirements of grid enterprise information security protection,based on the research on the related smart grid service scenarios,architecture and security requirements of the wireless public network as the channel,the intelligent distribution wireless public network channel monitoring architecture,including intelligence A monitoring scheme for the use of electrical service terminals,system main stations,and wireless public network channels.The classification and identification method of wireless public network access service based on Bayesian algorithm is studied,and the service terminal security separation layer isolation scheme based on this is studied.The validity of classification and identification of access service data is verified by simulation.A dynamic security authentication method based on multi-factor wireless public network access with biometrics is designed.The identification method of wireless public network intrusion attack based on attribute-added Bayesian and support vector machine is studied,and the security situation awareness and early warning model of wireless public network based on actual combat is constructed.The two parts of the intrusion detection classification based on support vector machine and Bayesian are validated by simulation.Based on the above research,according to the implementation progress requirements of the technology project of Nanwang Company,the deployment scheme of wireless public network security access intelligent power channel monitoring is designed.The simulation power distribution main station is used as the test environment,and the wireless public network is designed.The channel safety situational awareness simulation test plan lays the foundation for the field function verification and promotion of the early warning model.
