Addressing cybersecurity challenges in rail

Cybersecurity challenges in railway digitalization 

Railway systems are undergoing rapid digital transformation, integrating advanced control systems, connected infrastructure, and IoT-enabled assets. While these technologies enhance performance and efficiency, they also expand the attack surface for cyber threats. From signalling systems and control centres to rolling stock and passenger services, critical assets face increasing exposure to malicious activity. 

Legacy systems, IT/OT convergence, remote access points, and third-party suppliers further complicate risk management. Against this backdrop, operators, manufacturers, and infrastructure managers must adopt a comprehensive approach to cybersecurity – one that addresses not just compliance, but long-term operational resilience and stakeholder trust.
