Case Study: Major Australian Rail Operator strengthens cyber resilience with NCC Group

Strengthening Cyber Resilience for an Australian Rail Organization

Major Australian Rail Operator, a major rail operator in Victoria, Australia, worked with NCC Group to strengthen cyber resilience across its Operational Control Systems (OCS) and Train Control Systems (TCS). The organization faced growing cyber threats to global rail networks, along with highly interconnected legacy systems, limited segmentation, and complex stakeholder and data flows across safety-critical operations.

NCC Group, in partnership with Ricardo, delivered a structured cyber resilience uplift program that included network assessments, segmentation recommendations, and secure architectural guidance. The engagement produced a detailed roadmap and functional specification for staged implementation, helping the operator improve identity, confidentiality, integrity, and availability across operational data flows while enhancing protection for critical rail infrastructure without disrupting train services.
