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.

CM-8 System Component Inventory
addresses: CWE-912

Documenting every system component at the required granularity and reviewing the inventory detects or prevents hidden functionality from remaining undetected.

CP-10 System Recovery and Reconstitution
addresses: CWE-912

Recovery eliminates hidden functionality or backdoors introduced during compromise.

PM-30 Supply Chain Risk Management Strategy
addresses: CWE-912

Policy requires supplier transparency and testing to detect hidden functionality or backdoors inserted in the supply chain.

PS-2 Position Risk Designation
addresses: CWE-912

Screening high-risk technical positions lowers the probability that hidden functionality or backdoors will be added by authorized personnel.

RA-10 Threat Hunting
addresses: CWE-912

Hunting identifies hidden functionality used for persistence or evasion after initial compromise.

RA-6 Technical Surveillance Countermeasures Survey
addresses: CWE-912

TSCM surveys discover and eliminate hidden surveillance functionality that would otherwise remain undetected in the environment.

SA-10 Developer Configuration Management
addresses: CWE-912

Change control, approval gates, and flaw tracking force hidden functionality to be either documented or discovered and removed.

SA-12 Supply Chain Protection
addresses: CWE-912

Vetting and integrity controls during acquisition reduce the likelihood of hidden backdoors or malicious functionality introduced by suppliers.
