基于自适应安全的铁路网络安全框架设计研究

介绍自适应安全框架的定义与特征，结合新形势下的铁路信息系统网络安全保障需求，从基础结构安全、纵深防御、主动防御、联防联治4个方面，提出基于自适应安全的铁路网络安全框架设计思路，并围绕该框架形成风险纵深安全防御、数据纵深安全检测、自动化快速响应、安全情报预警4个重点研究方向，通过体系化的建设模式，提升铁路网络安全防御自适应能力。

Railway network security framework based on adaptive security

This paper introduced the definition and characteristics of adaptive security framework. Combined with the requirements of railway information system network security under the new situation, from four aspects of infrastructure security, defense in depth, active defense, joint defense and joint governance, the paper proposed the design idea of railway network security framework based on adaptive security, and formed four key research directions of risk in-depth security defense, data in-depth security detection, automatic rapid response and security information early warning around the framework. Through the systematic construction mode, it can be improved the adaptive ability of railway network security defense.
