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 promotes least privilege by defining necessary privileges and management commitment to them.
Supervision detects and allows removal of unnecessary privileges that enable execution with excess rights.
Reviewing accounts for compliance, disabling/removing unneeded accounts, and aligning with termination processes prevents execution with unnecessary privileges.
Separation of duties prevents any single user from holding all privileges needed to complete a critical task, directly reducing execution with unnecessary privileges.
Directly prevents execution with more privileges than needed for assigned tasks.
Role-based training on least privilege principles reduces the chance personnel assign or retain unnecessary privileges.
Analysis of audit records can identify execution with unnecessary privileges through unusual activity patterns.
Automatic termination after a defined period eliminates unnecessary privileges from persistent connections.
