Applicability & intent
A useful methodology defines scenarios, assets or processes, likelihood and impact scales, control assumptions, uncertainty, aggregation, and decision criteria.
- Document why cyber risk methodology applies, what is in scope, and who is accountable.
- Translate obligations into owned, testable outcomes with proportionate evidence.
- Track exceptions, residual risk, changes, and corrective actions through governance review.
Governance lifecycle
- 01
Confirm scope, context, interested parties, legal or contractual basis, and authoritative sources.
- 02
Identify desired outcomes, owners, dependencies, existing controls, and evidence sources.
- 03
Assess design and operating effectiveness using representative, time-bound evidence.
- 04
Record gaps, risk, interim protections, target dates, and approval decisions.
- 05
Verify remediation, report residual risk, and schedule reassessment when context changes.
Evidence & assurance
| Evidence family | Assurance question |
|---|---|
| methodology and scoring definitions | Does governance establish accountable direction? |
| scenario analysis and assumptions | Does the process operate consistently? |
| review and approval records | Can the claimed outcome be independently verified? |
Evidence should be attributable, current, protected, reproducible, and linked to an accountable owner. A document alone does not demonstrate that a control operates effectively.
Readiness decisions
- Keep inherent and residual risk distinct.
- Record uncertainty and evidence quality.
- Calibrate scoring with real decisions and events.
