基于服务的IT应用中的用户身份管理

User Identity Management in IT Application Based on Service

针对IT应用中的用户身份访问控制问题,传统的基于角色的身份管理方案有紧密耦合的局限,并带来了管理成本和复杂度高等问题,通过对服务概念进行解释,用示例图展示了以服务为中心的模型运作;提出了采用基于服务的演化方法来应对身份管理的变化,可有效地增加组织的灵活性、降低管理成本和复杂度。

In view of the user identity accessing and controlling of IT applications, there exists some limitation on tight coupling in the traditional role - oriented identity management solutions, which has brought some problems like management cost and high complexity. A new evolved method was proposed to manipulate the changes in identity management by introducing the concept of service and illustrating the service - oriented model, which effectively enhances the flexibility as well as reduces the costs and complexity.
