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.
