- Reconcile the systems emitting logs against the asset inventory — the machine that never appears in the log platform is the one this requirement is about.
- Set retention deliberately: long enough for investigations that start months late, affordable enough to survive budget review, and written into the records retention policy the requirement points at.
- Watch for silent generation failures — stopped agents, filled quotas; the alerting in 03.03.04 depends on someone noticing here.
03.03.03 — Audit Record Generation
03.03 Audit and Accountability · NIST SP 800-171 Rev. 3
Requires generating audit records for the event types selected under 03.03.01, with the record content defined under 03.03.02, and retaining those records for a time period consistent with the organization's records retention policy.
Rev. 3 requirement text is multi-part and parameterized with organization-defined values, so this site summarizes rather than reproduces it. The summary is independent — read the official publication for the binding wording.
NIST SP 800-171 Rev. 3 — Protecting CUI in Nonfederal Systems ↗NIST SP 800-171A Rev. 3 — Assessing Security Requirements for CUI ↗What this requirement is after
Deciding what to log and what a record contains means nothing until systems actually emit those records and keep them long enough to matter. This is the operational half: generation everywhere the decisions apply, and retention aligned with the organization's records policy rather than whatever the default rollover happens to be.
Splits generation and retention out of Rev. 2's 3.3.1 into an explicit requirement tied to the selections made under 03.03.01 and 03.03.02.
Brilliant at the Basics practices that support this requirement
The campaign’s twenty practices are a priority list, not a control catalog, and none of them works this requirement’s substance directly. It still applies to you if it is in your contract’s scope: address it through your own implementation and the related artifacts below, and treat the absence of a mapping here as honesty, not permission to skip it.
Implementation considerations and evidence
- A log-source coverage report reconciled against the inventory
- Retention configuration and the records policy naming the period
