The Airbus Approach for Cyber Security in the Rail Sector
The rail sector is shifting to a new paradigm of digitalisation to bring in efficiencies to counter the increased demands of travelling passengers and goods transport, while ensuring the highest safety and security of the infrastructure. To achieve this goal, Rail Operators have adopted modern systems combining IT and IoT technologies. Digital transformation strategies within the Rail sector include more connectivity for Industrial Control Systems (ICS), increasing their exposure and potentially making them more vulnerable and exposed to cyber-attacks.
As global railway networks undergo rapid digital transformation—integrating automated signalling, Internet of Things (IoT) sensors, connected rolling stock, and cloud-based traffic management systems—their attack surfaces expand significantly. This specialised white paper by Airbus Protect addresses the unique security challenges facing modern rail operators and infrastructure managers. By bridging the gap between functional railway safety and operational technology (OT) cybersecurity, the paper presents a structured methodology for identifying critical assets, ensuring compliance with international standards (such as IEC 62443 and CLC/TS 50701), and implementing robust defence-in-depth measures to safeguard passenger safety, operational availability, and transport continuity.
