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.

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.

PR.PS-06 full match
prevents

Secure SDLC practices directly prevent introduction of undocumented hidden functionality during development.

ID.RA-09 mostly match
prevents

Pre-acquisition integrity/authenticity checks can detect undocumented hidden functions in supplied software/hardware.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development and acceptance can discover undocumented functionality before release.

A.8.32 Change management mostly match
prevents

Change management processes can catch unauthorized additions but do not inherently prevent hidden functionality from being introduced.

A.8.16 Monitoring activities partial match
finds

Monitoring activities can detect anomalous behavior from hidden functions but do not eliminate the weakness.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates documented requirements and design reviews that would expose undocumented hidden functionality.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly define expected functionality, making hidden features a violation.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture and engineering principles require transparent, documented designs that preclude hidden functionality.
