Optimization of Information Security Management Mechanism for Distribution Network Information Storage Based on RBAC and Development of Visual Operation and Maintenance Platform

Facing the challenge of information storage security brought by the rapid development of distribution network technology, this paper analyzes the essential requirements and current security problems of distribution network information storage and designs. It implements a set of security management schemes based on the RBAC model. User authentication and authorization processes are emphasized to ensure only authorized users can access critical information resources. The application in the actual distribution network environment shows that the scheme can improve the security performance of the system, reduce unauthorized access attempts by up to 40%, and improve data processing efficiency by about 30%. The scheme also reduces the complexity of system maintenance, and the number of security events that administrators need to deal with is reduced by about 50% compared to traditional security mechanisms. These data fully prove that the security management mechanism based on RBAC is efficacious in improving the distribution network’s information storage security and operational efficiency. This article proposes and studies an optimization scheme for information security management mechanisms based on RBAC in distribution network information storage technology. This scheme effectively improves the security and reliability of the distribution network information storage system through refined permission management and access control. This study provides innovative strategies, empirical data for distribution network information storage security management, and valuable references for future research on power grid information security. © 2024 River Publishers.
