| 2. | Linux has been more and more widely used today , but the secure degree of linux is low , so in this paper , we produce a linux - compatible secure operating system , named slinux . its design object is in accordance with the requirements of the fourth level , i . e . structured protection level , of gb17859 . for this purpose , we introduce such mechanism , as identification & authentication , mac , least privilege manage , trusted path , password management . object reuse , covert and channel analysis . furthermore , we have some innovation , introduce the mechanism of network security and audit
本论文的研究目的是对linux进行安全增强，设计一个新的安全操作系统，即slinux安全操作系统，其设计目标是满足gb17859第四级《结构化保护级》的需求，为此我们在原有linux操作系统的基础上引入了标识与鉴别机制， mac机制，最小特权管理机制，可信通路机制，密码处理机制，客体重用机制以及隐通道分析机制，同时还进行了创新，引入了网络安全保护机制和审计机制。 |
