Research On Power Enterprise Network Security Model Based On Improved PDRR Model

With the high-speed development of modern science and technology level of the society, the electric power enterprise toward a more open, standardized, and the direction of network interconnection. Therefore, the safe operation of power system for network information system security becomes more dependent on. Although the electric power enterprise implements the earlier production management informationization, but the network information security architecture is not perfect, the existing network information security model is not fully applicable to electric power enterprises, this will cause the electric power enterprise can’t to comprehensive enterprise network information security protection. Therefore, in urgent need of a sense of power enterprises targeted strong network security model to enhance the strength of the network information system security.In this paper, based on the analysis of power enterprise network information system security situation, the power companies to build a model based on improved PDRR network security model. The PDRR model is a classical network security model which is composed of four modules:protection, detection, response and recovery. The improved model on the basis of, safety monitoring, response, recovery, strategies, such as reinforcement technology and people, management, laws and regulations, education and training many influence electric power enterprise network security effectively combine together, to Chifeng power supply network, the network information security architecture as an example, the secondary fuzzy comprehensive evaluation method of existing architectures for safety grade evaluation and find the existing defects. Based on this, the security reinforcement scheme is designed and realized, which is proved to have the practicability and effectiveness of the improved network security model.This paper research proves that the improved power enterprise network security model can make Chifeng power company network information system stronger, also to other small and medium-sized power network enterprise information system construction to provide a reference basis, to the electric power enterprise is no longer just rely on the network information system construction technology and safety product stack, but rather in the direction of the technology and management development, improve the electric power enterprise network information security levels.
