摘要
基于角色的存储控制 (RBAC)模型在企业级应用环境中非常成功。在大型企业里 ,怎样进行有效的RBAC管理是一个越来越重要的问题。众所周知 ,ARBAC97是集中RBAC管理的模型。ARBAC97通过“角色层次”和“约束条件”来管理角色 ,虽然在某些方面进行得不错 ,但是这种机制有明显的缺陷。
Role-Based Access Control(RBAC) is recognized as an excellent model for access control in an enterprise environment.In large enterprises,effective RBAC administration is a major issue.ARBAC97 is a well-known solution for decentralized RBAC administration.ARBAC97 authorizes administrative roles by means of ″role ranges″ and ″prerequisite conditions″ .Although attractive and elegant in their own right,we will see that these mechanisms have significant shortcomings.We adopt the organization Structure in workflow systems for Role Hierarchy Management.
