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.
Per-request decision making makes it harder to bypass authorization using user-controlled keys without proper validation in the decision process.
Enforces proper privilege management by requiring all decisions through the verified reference monitor.
Consistent enforcement of approved authorizations makes bypassing via user-controlled keys ineffective.
By mandating division of duties across roles, the control enforces proper privilege management and prevents a single entity from controlling an entire sensitive process.
Implements core proper privilege management by restricting to only required rights.
