随着无人驾驶技术、城轨云技术、互联互通等网络化新技术在城市轨道交通中的广泛应用,导致信号系统内外部接口大量增加,随之带来内部与外界对系统网络环境的恶意攻击。作为地铁的“大脑”,信号系统信息安全尤为重要。通过分析信号系统的整体网络架构,针对信号系统信息网络安全隐患及防护现状,提出了信号系统信息安全主被动防御体系,将现有的主动防御和被动防御技术相结合,建立了基于等级保护的被动防御模型,和从安全技术、安全策略、安全管理三个维度出发提出了主动防御模型,达到了充分保障信号系统的信息网络安全的效果。

[Abstract]
With the extensive application of new networking technologies such as Self-driving technology, urban rail cloud technology and interconnection in urban rail transit, a large number of internal and external interfaces of the signal system are increased, which brings malicious attacks to the system network environment from both inside and outside. As the "brain" of subway, information security of signal system is particularly important. By analyzing the overall network architecture of the signal system, the active and passive defense system of the information network security of the signal system is proposed in view of the hidden dangers and protection status of the information network security of the signal system. The passive defense model based on hierarchical protection is established by combining the existing active defense and passive defense technologies. And put forward the active defense model from three dimensions of security technology, security policy and security management, which can fully guarantee the information network security of signal system.
