IA-4(4) Identifier Management | Identify User Status
Manage individual identifiers by uniquely identifying each individual as organization-defined characteristic identifying individual status.
Source: NIST SP 800-53 Rev 5, IA-4(4). The statement above is our statement of the clause, read from the published text and cited so you can check it against the official text, not the instrument verbatim. Open NIST SP 800-53 Rev 5 in the compliance library.
Base controls and their enhancements. Which apply follows the baseline you are assessed against (for example FedRAMP Moderate or High, or the low, moderate and high baselines of SP 800-53B). Text in square brackets is a parameter your organisation sets.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Identifiers do not indicate the organization-defined user status such as contractor or foreign national
- The characteristic used to identify individual status was never defined, so status cannot be determined from identifiers
