Operational Data Disclosure Risk Matrix for Industrial Control Systems
This is not a legal opinion, cybersecurity assessment, disclosure authorization, or formal classification system. It is an educational discussion aid intended to support better conversations and professional judgment. Final decisions should involve qualified legal, operational, OT, cybersecurity, engineering, and records personnel as appropriate.
The Operational Data Disclosure Risk Matrix for Industrial Control Systems is an educational spreadsheet tool designed to help teams think more carefully about operational data before it is released, shared, stored, aggregated, or provided to outside parties.
Industrial control system data is not always harmless just because it is not a password, network diagram, or vulnerability report. SCADA exports, historian records, alarm logs, equipment records, runtime data, asset information, and vendor datasets can reveal how a system operates when they are viewed in context or combined with other information.
This matrix gives ICS, OT, engineering, cybersecurity, records, legal, and operations teams a structured starting point for discussion.
It includes review prompts for:
- SCADA and historian data
- Alarm and event records
- Asset and equipment information
- Control system documentation
- Network and remote access information
- Cybersecurity and incident records
- Vendor, AI, and third-party data use restrictions
- Public records and external disclosure scenarios
The tool helps teams think about operational sensitivity, cyber/OT sensitivity, OPSEC inference risk, reviewer involvement, safer disclosure options, and decision rationale.
