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.

addresses: CWE-200 CWE-250

Audit record review and analysis can detect unauthorized exposure or access to sensitive information.

addresses: CWE-200 CWE-250

Trained staff understand data-handling requirements and are less likely to expose sensitive information through misconfiguration or poor design.

addresses: CWE-200 CWE-250

Minimal information storage directly reduces the quantity of sensitive data resident on the component that could be exposed.

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-200

Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.

addresses: CWE-200

Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.

addresses: CWE-250

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