铁路SIM卡管理系统网络安全防护方案研究

Study on Network Safety Protection Scheme of GSM-R SIM Cards Management System

通过分析铁路GSM-R SIM卡管理系统运用现状及业务拓展应用需求,参考现有信息系统安全等级保护要求,并结合铁路通信网自身网络安全防护现状和应用特点,研究铁路GSM-R SIM卡管理系统接入铁路数据通信网的网络安全防护技术要点,探索在铁路数据通信网上承载SIM卡管理等关键业务的网络安全。

Through the analysis of the application status and business developing demands of GSM-R SIM cards management systems, the paper studies key points of network safety protection techniques as accessing GSM-R SIM cards management system into railway data communication network from reference to the safety levels protection requirements of existing information systems and its own safety protection status and application features of the railway data communication network, and discusses the network safety for bearing key businesses like SIM cards management over railway data communication networks.
