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.

AT-3 Role-based Training
addresses: CWE-311 CWE-319

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

CA-3 Information Exchange
addresses: CWE-311 CWE-319

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

CM-13 Data Action Mapping
addresses: CWE-311 CWE-319

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

CM-6 Configuration Settings
addresses: CWE-311 CWE-319

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

PM-17 Protecting Controlled Unclassified Information on External Systems
addresses: CWE-311 CWE-319

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

SA-9 External System Services
addresses: CWE-311 CWE-319

Privacy and security requirements placed on external providers, together with monitoring, tangibly reduce missing encryption of sensitive data processed or stored by those services.

SC-13 Cryptographic Protection
addresses: CWE-311 CWE-319

Mandates encryption for specified data uses, directly preventing missing encryption of sensitive information.

MP-1 Policy and Procedures
addresses: CWE-319

Policy addresses secure transport and handling of media to avoid cleartext transmission of sensitive information.

PR.DS-02 partial match
blocks

Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-311, a class-level weakness. Rules are authored against its narrower children: CWE-312.
