摘要
信息安全问题日益严重,操作系统的安全显得尤为重要。而Linux的安全等级仅接近国家标准一级安全标准,因此需要对Linux系统的安全性进行完善,设计Linux安全操作系统达到国家三级安全标准以上。本文着重论述利用Linux支持的可加载内核模块实现的基于强制访问控制的Linux安全操作系统的体系结构及其功能单元和相关技术细节。
The information security becomes increasingly important,especially the security of the operating system.The security grade of the Linux operating system had just approached the 1st grade defined in GB 17859 - 1999. Thereby we attempt to improve the Linux system security so as to design the Linux security operating system to exceed the 3rd grade defined in GB 17859 - 1999. In the system we realize several security features including the mandatory access control, security audit, and etc. This paper focuses on discussing the architecture of the MAC - based Linux security operating system implemented with LKM supported by Linux, and introduces the key technica of implementation.
