About this tag
Safety-critical systems are foundational to industries like railway transportation, where protocols such as End-of-Train (EoT) and Head-of-Train (HoT) must be secured against vulnerabilities that could enable malicious brake commands. Recent cybersecurity research highlights weak authentication in these legacy protocols, prompting responses from industry bodies like the Association of American Railroads. Additionally, CISA's 2025 ICS advisories underscore the fragility of interconnected critical infrastructure, offering mitigations for vulnerabilities in industrial control systems. These discussions emphasize the urgent need for resilient security measures in safety-critical environments, where failures can disrupt entire lines of rail traffic or compromise essential services.
