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-345 CWE-353

Mandates provision of authenticity and integrity artifacts that enable verification of name/address resolution data.

addresses: CWE-345 CWE-353

Control requires verification of data authenticity/integrity (e.g., checksums) after aggregation/packing, directly reducing exploitation of insufficient verification before transmission.

addresses: CWE-353 CWE-345

Directly supplies the missing integrity verification mechanism the weakness describes.

addresses: CWE-345 CWE-353

Provenance documentation and monitoring directly enables verification of authenticity for components and data throughout their history.

addresses: CWE-345 CWE-353

The control implements verification mechanisms that detect tampering by ensuring data authenticity.

addresses: CWE-353

Irrefutable evidence of actions requires integrity protection to prevent tampering or alteration of records.

addresses: CWE-353

Implements required signature-based integrity verification, addressing missing support for integrity checks on components.

addresses: CWE-345

Directly requires independent verification of matching output before adverse decisions, mitigating insufficient authenticity checks on data from external sources.
