摘要
基于角色访问控制的权限访问控制系统能严格地控制与防止用户接触与其身份角色不相关的数据信息,有效地避免用户的非法操作,从而切实地提高系统的可用性和健壮性。本文以一个网上教学系统的权限访问系统实现为例,研究和探讨了实际应用中用户访问控制的设计及实现。
The system which is based on the role-based access control technology can control the access authorized data, and avoid the illegality access. The practicability, and robustness in the system are evident. By taking an online teaching system as a practical example,this paper discusses how to design and implement a security subsystem.
