铁路计算机网络安全系统建设和应用

Implementation and application of China Railway Computer Network Security System

铁路计算机网络安全系统基于"应用分区、网络分层、安全分级"的思想,实现铁路计算机网络基础设施、网络边界和局域网环境的安全保障。介绍构成铁路计算机网络安全系统平台的铁路行业数字证书认证、统一用户管理和资源管理、访问控制、病毒防护和应用系统的安全服务5个子系统及其应用,并结合铁路信息化发展提出进一步建设铁路计算机网络安全保障体系的构想。

The China Railway Computer Network Security System was based on the concept of ＂applied system grouping, computer network layering and security grading＂ to implement a security safeguard of the railway computer network infrastructure, the computer network borderline and the LAN environment. It was described the China Railway Computer Network Security System and it＇s five subsystem as well as their applied, as railway computer application, unified user and resource management, access control, virus protection and applied system service. Also, according to China Railway Information System construction, it was outlined the Chinese railway computer network security architecture.
