拟态防御在铁路网络安全应用的初步探讨

Mimicry defense applied to railway network security

文章介绍了拟态防御技术的基本思想和动态异构冗余架构模型,从整体架构分析和局部算法改进两个方面对拟态防御的技术理论研究进行了总结,深入分析了铁路纵深防御体系面临的问题和采用拟态防御的必要性。结合铁路实际需求和应用场景,从部分设备拟态改造、整体网络架构拟态改造、系统拟态改造3方面对拟态防御技术实践应用开展分析,对提升铁路主动防御能力具有参考意义。

This paper introduced the basic theory of mimic defense technology and the Dynamic Heterogeneous Redundant architecture model,summarized the technical theoretical research of mimic defense from two aspects of overall architecture analysis and local algorithm improvement,and deeply analyzed the problems faced by the railway defense-in-depth system,and the necessity of mimic defense.Combined with the actual needs and application scenarios of railway,the paper analyzed the practical application of mimicry defense technology from three aspects:some equipment mimicry transformation,overall network architecture mimicry transformation and system mimicry transformation,which had great reference significance for improving the active defense capability of railway.
