Sanctions Data Hygiene Checklist
The data hygiene checklist that keeps screening honest.
How to use
How to use: run monthly and after any data-source change. A stale list is a compliance gap.
List freshness
- SDN mirror updated within the last hour
- Sync failures alert the on-call
- Failing closed during sync outage
Versioning
- Every screen result records the list version
- Historical results re-checkable against the version used
- New designations re-screen previously cleared parties
Audit integrity
- Logs immutable (append-only)
- Logs retained for the enforcement window
- Blocked/flagged results reviewed weekly
Why this exists
A screen is only as good as the list it runs against. This checklist keeps the data honest.
