railway security

About this tag
The railway security tag covers discussions about cybersecurity vulnerabilities in railway systems, particularly focusing on the End-of-Train (EoT) and Head-of-Train (HoT) remote linking protocol used in North American rail freight. Recent research has exposed weak authentication in these critical protocols, which could allow malicious actors to send false brake commands and disrupt rail traffic. The content highlights the intersection of legacy industrial protocols with modern cybersecurity threats, emphasizing the need for improved security measures. Industry bodies like the Association of American Railroads (AAR) are responding to these findings. This tag is relevant for professionals concerned with securing critical infrastructure and industrial control systems.

  1. Railway Cybersecurity Alert: Weak Authentication in Critical EoT/HoT Protocols Threatens Safety

    In the world of railway transportation, safety-critical systems are the bedrock upon which the trust and reliability of global supply chains are built. Recent cybersecurity research into the End-of-Train (EoT) and Head-of-Train (HoT) remote linking protocol—an essential communications standard...
