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

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

SC-38 Operations Security
addresses: CWE-312

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