摘要
信息系统访问控制已越来越受到重视,特别是在办公自动化领域中控制资源访问要求的访问控制。但是传统的角色访问控制模型和任务访问控制模型并不能满足工作流多变的控制需求,针对此问题,引出了基于任务和角色的访问控制模型,它能够满足办公自动化所涉及的业务领域对权限管理的要求。最后,结合实际的办公自动化系统的开发,给出了基于任务和角色的访问控制模型的一个具体的应用实例。
Growing attention has been paid to access control in information system, especially the access control of resource access requires in office automation area. However, traditional role-based access control model and task-based access control model cannot satisfy the workflow changeable requirements. To solve these problems, the task-role-based access control mode is introduced, which can satisfy the requirements of authority managements from business fields related to office automation. At the end of the paper, combined with the practical development of office automation system, the detailed implementation instance of task-role-based access control mode is provided.
