Why should I care?
Sector context decides consequence. The same vulnerability carries a different risk in a substation, a treatment plant and a packaging line — prioritise on physical outcome, not CVSS alone.
Key processes
- Train movement authority
- Traffic signal coordination
- Passenger systems
- Tunnel and station services
Safety considerations
- Signalling safety integrity
- Emergency ventilation
- Passenger evacuation systems
Availability requirements
- Timetable-driven operation
- Very restricted maintenance access windows
Threat patterns
- Legacy fielded systems
- Wide geographic exposure
- Public-facing infrastructure
