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.

SC-28 Protection of Information at Rest
addresses: CWE-312 CWE-313

Requiring confidentiality protection for information at rest eliminates cleartext storage of sensitive data on persistent media.

AT-3 Role-based Training
addresses: CWE-312

Training on secure data handling discourages cleartext storage of sensitive information.

CM-13 Data Action Mapping
addresses: CWE-312

Data action mapping can detect storage actions that leave sensitive information in cleartext.

CM-6 Configuration Settings
addresses: CWE-312

Configuration policies can mandate secure storage methods to avoid cleartext storage of sensitive information.

MP-1 Policy and Procedures
addresses: CWE-312

Policy requires protection measures such as encryption for sensitive data stored on media, preventing cleartext exposure.

SC-12 Cryptographic Key Establishment and Management
addresses: CWE-312

Key-management policy requires protected storage of key material, preventing cleartext storage of sensitive cryptographic keys.

SC-38 Operations Security
addresses: CWE-312

Reduces cleartext storage of sensitive data when OPSEC identifies and mandates protection of key information artifacts.

PR.DS-01 full match
prevents

Encryption of data-at-rest directly prevents cleartext storage while the control also addresses integrity and availability.

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.8.24 Use of cryptography full match
prevents

Cryptography control directly mandates encryption of sensitive data at rest.

A.5.12 Classification of information partial match
prevents

Classification identifies sensitive data that must not be stored in cleartext.

A.5.14 Information transfer partial match
degrades

Transfer policies can require encryption, indirectly reducing cleartext storage risk.

A.7.14 Secure disposal or re-use of equipment partial match
mitigates

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.

A.7.9 Security of assets off-premises partial match
mitigates

Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.

A.8.10 Information deletion partial match
degrades

Deletion policies help remove sensitive cleartext files when no longer needed.
