remote linking protocol

About this tag
The remote linking protocol is a communications standard used in North American rail freight for End-of-Train (EoT) and Head-of-Train (HoT) devices. Recent cybersecurity research has identified weak authentication vulnerabilities in this protocol, which could allow attackers to send malicious brake commands and disrupt rail traffic. The Association of American Railroads (AAR) and industry committees are responding to address these security gaps. This tag covers discussions about the protocol's role in railway safety-critical systems, the discovered vulnerabilities, and the broader implications for legacy protocol security in transportation infrastructure.

    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...
