Designing Secure Network Segmentation: Giving Suppliers Access Without Exposing Critical Rail Systems

This session delivers a practical segmentation and access-control blueprint for protecting safety-critical OT environments while still enabling maintenance, analytics, and third-party collaboration.

How are organisations architecting segmented OT networks that restrict supplier access to only the systems they maintain?
Best practice applying standalone network principles to reduce attack surfaces and operational risk.
Strategies and solutions to safely separate operational control, analytics, and data distribution environments
How to apply Purdue-based segmentation models to real rail infrastructure and rolling stock
