一个基于生物免疫系统的网络安全模型

Network security model based on biological immune system

网络安全系统是一个复杂系统,现有安全防御能力十分有限.借鉴生物免疫系统的机理,构建多代理系统,通过安全检测与响应等环节的协同工作,使网络安全防御更具健壮性.文章分析了生物免疫系统的特性和机理,提出一个网络安全免疫模型,介绍了模型的组成和体系结构.新的网络安全模型具有健壮、分布、并行、自适应和协同等免疫特性.

A network security system is a complex system. Its defense function is limited. Based on immune principles the multi-agent system is constructed. It makes the detecting and responding stages cooperate so the defense system effects stabilization. The mechanisms of the natural immune system are analyzed in the paper. The new network security model is improved and the components and architecture of the model are introduced. The model has many immune features such as stabilization, distribution, parallel, self-adaptation, cooperation and so on.
