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.
Ensures privileges are assigned only as necessary rather than incorrectly over-granted.
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.
Establishes requirements for appropriate default permissions on system resources as part of configuration management.
Baseline establishment and updates on install/upgrade ensure correct default permissions rather than insecure ones.
Requiring the most restrictive settings instead of defaults prevents incorrect default permissions on resources.
