【摘要】 通过对基于策略的网络安全管理的研究,分析了现有网络安全策略冲突检测和消解方法存在的不足。基于策略求精的思想和安全策略冲突分类技术,建立基于策略的网络管理安全级模型,并用扩展的XACML语言加以描述。根据策略行为间的关系,采用知识推理技术,动态分层地对相应安全级策略进行一致性自动检测和实时冲突消解,使其具有良好的可重用性和可扩展性,以利于安全策略管理效率的提高。并通过策略求精访问控制的应用实现进行了验证。最后给出了未来的研究方向。更多还原

【Abstract】 Through policy-based network security management research,this paper analyzed the existing network secu-rity policy conflict detection and resolution method shortcomings.Based on policy refinement of ideas and security policy conflicts classification technology,policy-based network management security-level model was established,with exten-ded XACML language description.According to the relationship between policy behavior,using knowledge reasoning,dynamic layered security corresponding level of policy refinement consistency automatic detection and timely conflict resolution were made,letting it has a good reusability and scalability,and is conducive to the improvement of manage-ment efficiency.Policy-based access control refinement application implementation was verified.Finally,some of the fu-ture research directions were discussed.更多还原
