Access Control Mechanisms In Power System Based On Unified Platform: Research And Implementation

According to the construction of electric power information, informationsecurity issues are also increasingly prominent, and the various departmentshave established a variety of business application system, employees in thecorresponding business application system has its own identity, enterprisesystem reform, the departmental isolated also to break, followed by a differentapplication system using the intersection, employees have their own digitalidentity in the different systems, and so many of security problems, defensethat the enterprise information security, ensure the enterprise safetymanagement in control, in the information age in the enterprise puts forwardthe integration of internal environment system, wonder to build a unifiedsystem platform strategy.Power grid operators map is the core of the system, which is to reflectthe current status of the power running operation of electronic real-timeelectronic map. The management of the grid diagram alone the traditionalmanual process to maintain a single diagram for grid management operationshave been unable to meet the modern power grid business model quickly andaccurately, with the development and utilization of cloud computing, how touse a unified system platform to achieve a legitimate user self-management ofthe cloud platform, is now an urgent problem.The article based on enterprise unified platform as the carrier, to designconforms to the enterprise now and extensible access control policy, first inthe traditional access control models are studied, as well as the combinationof enterprise internal environment system analysis of traditional models areinadequate, and the traditional access control model on the current cloudPlatform access and control permissions interaction problems in point blank,puts forward the improved access control model D-RBAC model. The modelhas solves the problem as1. Problems, about specific role division2. Theinteraction between roles, permissions delivery problem3. Senior roleinherited permissions unlimited scale-up problem.4. Users and permissions linkage problem.5. Enterprise Cloud Platform in the cloud resourcesinteractive competence.Finally, based on the D-RBAC model, the enterprises to build a unifiedsystem platform set the access control model, specifically description of thevarious D-RBAC modules design and application. Finally the model wasevaluated and tested.
