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.
Requiring an inventory that accurately reflects the system forces documentation of all components, making inclusion of undocumented features or chicken bits harder to achieve without detection.
Review and update processes include scrutiny of undocumented features or debug mechanisms provided by component manufacturers.
Requires transparency and verification of delivered components, limiting undocumented features or debug hooks introduced upstream.
Discourages undocumented features or chicken bits by demanding transparency and verification that only intended, documented behavior is present.
Developing critical components internally avoids undocumented features and chicken bits present in vendor hardware or software.
Requiring screened developers with proper access limits the introduction of undocumented features or debug 'chicken bits' that could be exploited later.
Inspection can uncover undocumented features or chicken bits that result from tampering or malicious insertion.
