Analysis of Security Threats and Vulnerabilities for Train Control and Monitoring Systems

摘要

Future railway systems should bring convenience to people's lives. In fact, the efficiency and the safety of railway services are improving due to the evolution from bespoke stand-alone systems to open-platform, standardized equipment and the increasing use of networked control and automation systems and connected technologies. However, this dependency of automation, control and communication technologies makes railway systems increasingly vulnerable to cyber-physical security threats which affect the overall performance. This paper deals with cyber-physical security concerns facing these systems. As such, vulnerabilities and characteristics of railway threat landscape are analyzed. We then discuss threats facing these assets, their direct impacts and cascading consequences on the whole system.
