摘要
针对传统计算机安全防护理论的不足,提出了一种采用生物免疫思想解决主机安全问题的方法。该方法确定了主机免疫系统的目标,即实现自适应分布式主机安全防护,设计了主机免疫系统的结构框架,对各组成部分进行定义和描述,同时给出了生物免疫系统与主机免疫模型组件映射关系表,在此基础上提出了系统的数学模型并讨论了模型的重要特征,重点对分布式特性、协同刺激和多样性进行了分析。讨论与仿真结果表明,该设计基本达到主机免疫系统模型的5项设计目标。
Nature immune systems provide inspiration for computer security.In order to solve the problems of traditional host security. Combined with traditional computer security defense theory, a new method was brought forward with immune idea. The goal of host immune system was given, that is to realize the self adaptation and distributed host security defense.The framework of host immune system, defining and describing all parts of the model was given. The mathematical model and several important features was put forward, the distributing and diversity characters are mathematically analyzed.The results of analysis show that HIM reaches five aims given in advanced.
