基于策略适应性的安全Linux操作系统研究与实现

Research and Implementation of Policy Flexibilities Based Secure Linux Operating System

安全操作系统的研究和开发是当前信息安全研究领域的重点和难点.安全策略及其适应性是安全操作系统的关键.介绍安全策略的概念和分类;根据策略适应性的要求,在分析Linux内核机制的基础上,设计并实现一种新的安全Linux操作系统强制访问控制实现模型,给出系统的体系结构和运行机制;分析了该模型的特点和性能.

The research and development of secure operating system are the key points and difficulties of current information security research areas. Security policies and its flexibility are vital to the secure operating system. In this paper we introduce the concepts and classes of the security polices, analyze the Linux kernel mechanisms. Then, we propose a new secure operating system mandatory access control implementation model in accordance with the request of policy flexibilities. Finally, the model's features and performance are analyzed.
