传统的基于角色的访问控制(RBAC)模型角色分配方式单一,权限模块功能过于简单,难以满足当今日趋复杂的系统需求。文中从角色分配方式和权限配置模块入手,增加了“角色组”的概念,提出了配置权限的三部分内容,形成了改进的RBAC模型;并且针对某电网公司的设备监测系统中权限分配的问题,设计出了适用于该系统的一套灵活的权限管理模式,有效的解决了该系统的用户权限的管理问题,且由于灵活性强,能很好地适应业务需求的发展和变化。
The traditional role-based access control (RBAC) model has a single role allocation model and the rights module is too simple to meet the needs of today’s increasingly complex systems. In this paper, the concept of “role group” is added from the role allocation mode and the authority configuration module, and the three parts of the configuration authority are proposed to form an improved RBAC model. And for the distribution of rights in the equipment monitoring system of a power grid company The system designs a set of flexible rights management model which can effectively solve the user rights management problem of the system and can flexibly adapt to the development and changes of business requirements.
