新形势下铁路网络安全防御机制研究

Railway network security defense mechanism under new situation

根据新形势下网络安全防御的特征及铁路网络安全的防御需求,围绕整体防御、防御执行、技术研究和协作防御4个方向,提出了新形势下的铁路网络安全防御机制。该机制基于入侵检测、拟态防御及威胁事件分析等关键技术,以防御框架为主导,纵深技术攻关及协作防御,以期实现铁路网络安全防御的快速响应和连贯执行,进一步提升铁路网络安全防御能力。

According to the characteristics of network security defense under the new situation and the defense requirements of railway network security,this paper proposed a railway network security defense mechanism under the new situation around four directions:overall defense,defense execution,technical research and cooperative defense.This mechanism was based on the key technologies such as intrusion detection,pseudo defense and threat event analysis.It took the defense framework as the leading role and was in depth technical breakthrough and cooperative defense,with a view to realizing rapid response and consistent implementation of railway network security defense,and further improving the railway network security defense capability.
