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
- Raw water intake
- Treatment and dosing
- Distribution pressure
- Wastewater collection and treatment
Safety considerations
- Chemical dosing limits
- Public health protection
- Confined space and chemical handling
Availability requirements
- Continuous supply obligations
- Limited redundancy at small sites
Threat patterns
- Internet-exposed remote access to HMIs
- Weak or shared credentials
- Opportunistic targeting of small utilities
