NIST-AC-2(7) Privileged User Accounts

(a) Establish and administer privileged user accounts in accordance with [Selection (one of): a role-based access scheme; an attribute-based access scheme]; (b) Monitor privileged role or attribute assignments; (c) Monitor changes to roles or attributes; and (d) Revoke access when privileged role or attribute assignments are no longer appropriate.

Privileged roles are organization-defined roles assigned to individuals that allow those individuals to perform certain security-relevant functions that ordinary users are not authorized to perform. Privileged roles include key management, account management, database administration, system and network administration, and web administration. A role-based access scheme organizes permitted system access and privileges into roles. In contrast, an attribute-based access scheme specifies allowed system access and privileges based on attributes.
