What it means
OT consequence-driven risk analysis starts with unacceptable physical, safety, environmental, operational, and business outcomes, then identifies the cyber-enabled paths that could produce them.
Why it matters
Asset-by-asset vulnerability lists can prioritize technical severity while missing combinations and process conditions that create the greatest real-world harm.
Practical focus
- Define unacceptable consequences with operators, engineers, safety, business, and emergency stakeholders.
- Map process functions, dependencies, control actions, safeguards, failure modes, threat paths, and conditions required to reach each consequence.
- Select mitigations that interrupt multiple paths, preserve safety, and can be verified under realistic operating conditions.
- Preserve this evidence: Retain consequence definitions, process and dependency models, scenarios, assumptions, path analysis, controls, residual risk, owners, and tests.
- Exercise this failure scenario: Resources are spent closing numerous low-consequence findings while a feasible path to a severe process or safety outcome remains untreated.
Common mistakes
- Using the label OT Consequence-Driven Risk Analysis without defining scope, ownership, decision authority, and the exact data, systems, people, or process affected.
- Treating a policy, contract, diagram, dashboard, or tool demonstration as proof that OT Consequence-Driven Risk Analysis operates consistently in production.
- Closing work without retaining the evidence needed to reconstruct the decision and verify the intended control outcome.
- Testing only the normal path and never rehearsing the failure condition: Resources are spent closing numerous low-consequence findings while a feasible path to a severe process or safety outcome remains untreated.
