Evidence & assurance
| Evidence family | Assurance question |
|---|---|
| breach facts and affected data subjects | Does governance establish accountable direction? |
| risk assessment and notification decision | Does the process operate consistently? |
| authority or individual communications and timeline | 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
- Start the regulatory decision clock promptly.
- Document decisions even when notification is not required.
- Coordinate facts without delaying containment.
