论文摘要
我们介绍了拟议的安全架构Deutsche Bahn计划部署，以保护其跟踪安全至关重要的信号系统免受网络攻击。我们首先介绍使用标准组件构建的现有参考互锁系统。接下来，我们提出一种分类法，以帮助建模与铁路环境相关的攻击向量。在此基础上，我们提出了提议的“分隔”防御概念，以确保即将到来的信号系统。
We present the proposed security architecture Deutsche Bahn plans to deploy to protect its trackside safety-critical signalling system against cyber-attacks. We first present the existing reference interlocking system that is built using standard components. Next, we present a taxonomy to help model the attack vectors relevant for the railway environment. Building upon this, we present the proposed "compartmentalized" defence concept for securing the upcoming signalling systems.
