duties of individuals requiring separation
163560·updated Aug 30, 2026This is a compositional phrase, not a term of art. In NIST SP 800-53 AC-5, it appears inside an organization-defined assignment parameter: "Identify and document [Assignment: organization-defined duties of individuals requiring separation]." The phrase simply names the object of that assignment — the set of role-based responsibilities an organization must enumerate before it can enforce separation of duties — and its meaning is fully assembled from its ordinary parts. The two-step operational expectation is to "identify the duties of individuals requiring separation" and then "define system access authorizations to support separation of duties," making plain that the phrase is a procedural instruction, not a coined concept.

This is a compositional noun phrase, not a term of art. It names the organization-assigned set of job functions or roles that an organization has determined must not be held or exercised by the same individual — the input that AC-5 requires an organization to identify and document. In NIST SP 800-53 Rev. 5, control AC-5 directs organizations to "identify and document [Assignment: organization-defined duties of individuals requiring separation]" and then define system access authorizations to enforce that separation. The phrase is a parameter placeholder — the bracketed "Assignment:" syntax signals that each organization substitutes its own concrete list of role conflicts — rather than a defined concept with a fixed meaning independent of that substitution. The underlying principle it serves is that separation of duties addresses the potential for abuse of authorized privileges and reduces the risk of malevolent activity without collusion, achieved by dividing mission or business functions and support functions among different individuals or roles.
Advisory only. A term this product ships is defined by an authority document, not by a search result.
