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 partial match
blocks

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

A.5.12 Classification of information partial match
blocks

A.5.12 only defines and communicates a classification scheme so that protection needs can be understood; it does not itself stop cleartext storage of sensitive data on disk, which requires other controls (e.g. A.8.24 cryptography or A.8.3 access restriction) to act on the classification.

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