eot protocol

About this tag
The eot protocol tag covers discussions about the End-of-Train (EoT) and Head-of-Train (HoT) remote linking protocol used in North American rail freight. Content highlights cybersecurity research exposing weak authentication in this safety-critical protocol, which could allow malicious brake commands and disrupt rail traffic. The tag includes analysis of legacy protocol vulnerabilities, industry responses from the Association of American Railroads (AAR), and the need for improved security in railway communications. This is a specialized topic relevant to industrial control system security and critical infrastructure protection.

  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...
