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-212

Eradication of spilled information from contaminated systems mitigates the effects of improper removal of sensitive data before storage or transfer.

addresses: CWE-212

The control requires verified removal of sensitive data before media is made available at a reduced classification level, directly addressing improper removal prior to storage or transfer.

addresses: CWE-212

Explicit procedures to delete inaccurate or outdated PII directly mitigate improper removal of sensitive information before storage or transfer.

addresses: CWE-212

Retention policies enforce removal or sanitization of sensitive data before storage or transfer per regulatory requirements.

addresses: CWE-212

The explicit requirement to delete inaccurate/outdated PII implements proper removal of sensitive information before further storage or transfer.

addresses: CWE-212

The control implements proper removal of sensitive information before storage or transfer of datasets.

addresses: CWE-212

The generate-on-demand-and-delete requirement enforces removal of sensitive information before storage or transfer, preventing improper retention.

addresses: CWE-212

Requires explicit removal of sensitive information prior to component transfer or disposal, reducing exposure from retained data.
