Practical examples of security throughout the entire OT lifecycle

Our experts Martin Koop, Johannes Häring and Markus Heinrich have published a technical article in Signal + Draht magazine that shows how cybersecurity requirements in railway applications can be structured and implemented in a practical manner across all life cycle phases – from design to decommissioning.

The article highlights:

• Cybersecurity management according to CLC/TS 50701 & IEC 62443
• Security by design along the EN 50126 V model
• Risk analysis, system hardening and security (pen) tests
• Vulnerability management, monitoring & SOC in operation

Added value for

• operators: Structured approaches to regulatory requirements (KRITIS, BSI, CRA) and secure, maintainable operation.
• manufacturers: Clear security requirements, verifiable evidence and better integration and acceptance capabilities.
• integrators: Increased efficiency as an interface between operators and manufacturers.

The article shows why cybersecurity in railway OT systems is not a one-off engineering issue, but a continuous process throughout the entire system lifecycle.
