Abstract

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. © Springer International Publishing AG 2017.
