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.
Policy addresses roles, responsibilities, and privilege management to prevent improper privilege assignments.
Access supervision ensures privileges are assigned and managed without improper escalation or retention.
Assigning group/role memberships and access authorizations (privileges) while reviewing accounts addresses improper privilege management.
The small, testable reference monitor reduces the likelihood of incorrect authorization implementations.
Certification evaluates whether authorization decisions are correctly implemented and enforced.
Periodic review and documentation of connection needs reduces incorrect authorization.
Restricting who can perform changes helps ensure privileges are managed properly rather than assigned broadly.
Manages privileges by authorizing only approved personnel and supervising those lacking required authorizations for maintenance.
