| 摘 要： | 安全操作系统(SOS)是建立在其上的系统的安全基石,有效的存取控制是实现SOS有效的措施和方法,应用在SOS系统中的存取控制方式主要有三种基于主体权限的存取控制方式、基于主客体操作的存取控制方式和基于角色的存取控制方式;基于访问控制方式建立的SOS模型的代表有:BPL模型、RBAC模型和Biba模型;三种存取控制方式和模型各有其特点.在实际SOS中这三种存取控制方式还能引起安全隐患,必须结合其他的安全措施和方法来提高操作系统的安全性.

| Abstract: | SOS is secure base of the system building on SOS; the effective Access Control is the effective measure and method implementing SOS. The three pattens of access control used in the models of SOS are the subject-right-based access control, subject & object operator-based access control, and role based access control; the access-control-based SOS typical models are the BPL, Biba and RBAC; the pattens of access control and the models have their characteristics. There are hidden dangers caused by Access Control in the running SOS, for improving security of the operating system other methods must be combined with. |
