Rail Service Risk Starts Outside the SIL Boundary

In this episode of Cybersecurity Under Pressure: Real Attacks, Real Problems, we explore the rapidly evolving threat landscape facing modern railway networks.

The era of 'security by isolation' is officially over, as digital twins, AI, and interconnected operational technologies turn railways into massive, distributed attack surfaces.

We break down real-world cyber incidents, including the 2023 Poland 'radio stop' attacks, the 2024 UK station Wi-Fi defacement, recent opportunistic incidents in Romania, and the severe service disruptions faced by Deutsche Bahn.

We also discuss the very real, day-to-day problems facing operators today: from vulnerable legacy infrastructure and unencrypted radio frequencies, to the rising threat of supply chain sabotage and autonomous 'agentic AI' attacks.

Join us as we analyze why hiding behind 'Non-SIL' (Safety Integrity Level) labels is a dangerous illusion that can collapse services and public trust, and how adopting technical specifications like TS 50701 and complying with the EU's NIS2 and CER directives can help transform reactive compliance into proactive cyber and physical resilience.
