Description
The modernization of railway systems with the introduction of autonomous trains and digitalization has revolutionized transportation, significantly enhancing connectivity and efficiency. However, this advancement has also exposed the railway network to a multitude of cybersecurity threats. Unlike other sectors, the railway industry was initially designed without considering cybersecurity measures, leaving it particularly susceptible to such risks. As connectivity becomes increasingly essential for improving services, the prevalence of cyberthreats poses significant safety concerns for the industry. This article delves into a comprehensive investigation of the safety and security mechanisms deployed to mitigate cyber threats within the railway sector. Specifically, the focus is on understanding the vulnerabilities inherent in the ERTMS/ETCS transmission system and the potential impact on overall system safety if exploited by malicious actors. By proposing cyberattack scenarios targeting the ERTMS/ETCS signalling system, this study aims to shed light on the critical cybersecurity challenges confronting modern railway networks.
