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.

addresses: CWE-250

Policy promotes least privilege by defining necessary privileges and management commitment to them.

addresses: CWE-250

Supervision detects and allows removal of unnecessary privileges that enable execution with excess rights.

addresses: CWE-250

Reviewing accounts for compliance, disabling/removing unneeded accounts, and aligning with termination processes prevents execution with unnecessary privileges.

addresses: CWE-250

Separation of duties prevents any single user from holding all privileges needed to complete a critical task, directly reducing execution with unnecessary privileges.

addresses: CWE-250

Directly prevents execution with more privileges than needed for assigned tasks.

addresses: CWE-250

Role-based training on least privilege principles reduces the chance personnel assign or retain unnecessary privileges.

addresses: CWE-250
