Cybersecurity for Rail Signaling Systems and Rolling Stock
Cyber attacks have already impacted rail systems in the USA, UK, Poland, Korea, Japan and many countries. The more digitized rail networks become, the more vulnerable critical signaling systems are to cyber sabotage. Increased signaling network connectivity and digitalization enable the adoption of modern positive train control (PTC) systems, cloud analytics, enterprise visibility into signaling operations, and vendor-monitored predictive maintenance systems, but at the same time introduce threats to safe, reliable and cost-effective operations. To maintain the highest level of safety and reliability, signaling network perimeters must be protected by Unidirectional Security Gateways.
