Digitalisation changes operation and maintenance in railways. Emerging digital technologies facilitate implementation of enhanced eMaintenance solutions through utilisation of distributed computing and artificial intelligence. In railway, the digital technology deployment is expected to improve the railway system’s sustainability, availability, reliability, maintainability, capacity, safety, and security including cybersecurity. In digitalised railway, aspects of cybersecurity are essential in order to achieve overall system dependability. Lack of cybersecurity imposes negative impacts on the railways like reputational damage, heavy costs, service unavailability and risk to the safety of employees and passengers. It has been observed, through open access data, that many railway organizations focus on detective measures of security threats with less emphasis on forecasting of cyber-attacks. In order to prepare in advance for cyberattacks, it is essential that Information and Communication Technology (ICT) and Operational Technology (OT) in railways need to undergo continuous updating towards security analytics approach. This approach will help the railways to produce proactive security measures to cyberattacks.
