Mitigating Controls

Likely Mitigating Controls AI

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.

AC-1 Policy and Procedures
addresses: CWE-250

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

AC-13 Supervision and Review — Access Control
addresses: CWE-250

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

AC-2 Account Management
addresses: CWE-250

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

AC-5 Separation of Duties
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.

AC-6 Least Privilege
addresses: CWE-250

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

AT-3 Role-based Training
addresses: CWE-250

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

AU-6 Audit Record Review, Analysis, and Reporting
addresses: CWE-250

Analysis of audit records can identify execution with unnecessary privileges through unusual activity patterns.

CA-9 Internal System Connections
addresses: CWE-250

Automatic termination after a defined period eliminates unnecessary privileges from persistent connections.
