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.

AT-3 Role-based Training
addresses: CWE-311

Privacy and security training stresses encryption of sensitive data, reducing missing encryption weaknesses.

CA-3 Information Exchange
addresses: CWE-311

Exchange agreements must document security requirements, which would include encryption to protect sensitive data in transit.

CM-13 Data Action Mapping
addresses: CWE-311

The map highlights data actions that involve sensitive data, enabling identification of missing encryption requirements.

CM-6 Configuration Settings
addresses: CWE-311

Settings can require encryption of sensitive data, preventing missing encryption weaknesses.

PL-8 Security and Privacy Architectures
addresses: CWE-311

Architectures must describe confidentiality protections, which includes mandating encryption for sensitive data in transit and at rest.

PM-13 Security and Privacy Workforce
addresses: CWE-311

Privacy and security curricula stress encryption requirements, reducing missing encryption of sensitive data.

PM-17 Protecting Controlled Unclassified Information on External Systems
addresses: CWE-311

Requires encryption and similar controls for CUI processed or stored externally, preventing missing encryption of sensitive data.

RA-5 Vulnerability Monitoring and Scanning
addresses: CWE-311

Monitoring detects missing encryption of sensitive data in storage or transit configurations.

PR.DS-01 mostly match
prevents

PR.DS-01 directly mandates encryption for data-at-rest and therefore prevents CWE-311 mostly for storage, yet the weakness also spans transmission and other contexts that this single at-rest control leaves unaddressed.

PR.DS-02 partial match
prevents

PR.DS-02 directly eliminates the transmission facet of CWE-311 via mandatory encryption but leaves the storage facet untouched, so each direction rates only partial.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.5.14 Information transfer partial match
prevents

Explicit rules requiring encryption for sensitive information in transit eliminate the weakness of sending data without cryptographic protection.

A.8.26 Application security requirements partial match
prevents

Explicitly calling for protection of data in transit and at rest, plus secure encryption of communications, drives the implementation of encryption that prevents clear-text exposure of sensitive information.
