Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Designation of a manager and policy dissemination ensures privileges are assigned according to defined roles.
Regular reviews catch incorrect privilege assignments to users, roles, or processes.
Explicitly specifying privileges and group/role memberships for accounts reduces the risk of incorrect privilege assignments.
The control requires explicit definition of separated access authorizations, making incorrect privilege assignments that bundle conflicting duties harder to implement.
Ensures privileges are assigned only as necessary rather than incorrectly over-granted.
