Defending a CBTC Signaling System with CylusOne

The latest wave of cyber-attacks had raised the cybersecurity issue to the top priorities of the Public Transport Operator. Moreover, the recent attacks on OT systems had convinced the Country’s cybersecurity authority that urban transport needed to upscale its protection measures, especially in areas that dealt with passenger safety. However, the signaling integrator was already well engaged in its detailed design phase and wasn’t willing to change its architecture, for cost and time reasons.
After preliminary discussions with Cylus on an architectural framework that could meet the challenges and requirements, the signaling integrator presented to the client a defense-in-depth protection relying on CylusOne Rail-focused Security Platform. Both the client and the National cybersecurity authority approved the solution.
Conclusions:
1. Safety and security can coexist without impacting the CBTC network’s performance or safety-case
2. Achieving cyber resilience and complying with the national cyber authority requirements.
3. Reduce overall security spending using 100% rail-focused multi function security suite
