Cyber-security risks and requirements in metro networks: A deep dive

摘要

Cyber-security in metro networks is evolving rapidly. Across the world, new metros are being built with a fresh look at cyber-resilience, which is materially impacting automation and other requirements. In parallel, older metros are evolving to become increasingly digitalised, with IT/OT connectivity requirements that must coexist with safety imperatives in systems such as communications-based train control (CBTC).
