Rail signalling used to be a closed, mechanical world. Today's networks run on digital command and control systems, cloud-based monitoring, and a growing web of connected sensors, which means the attack surface has grown right alongside the efficiency gains.
That's true of critical infrastructure generally, not just rail: the more operational technology gets bridged to standard IT networks, the more a phishing email in a back-office inbox can become a genuine safety and operations risk, not just a data breach.
For operators in this space, the starting point is the same as everywhere else: the people who touch these systems need to understand exactly how an attacker would try to get in, because the technology alone was never going to be the whole answer.
