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.
Training on secure data handling discourages cleartext storage of sensitive information.
Data action mapping can detect storage actions that leave sensitive information in cleartext.
Configuration policies can mandate secure storage methods to avoid cleartext storage of sensitive information.
Policy requires protection measures such as encryption for sensitive data stored on media, preventing cleartext exposure.
Key-management policy requires protected storage of key material, preventing cleartext storage of sensitive cryptographic keys.
Requiring confidentiality protection for information at rest eliminates cleartext storage of sensitive data on persistent media.
Reduces cleartext storage of sensitive data when OPSEC identifies and mandates protection of key information artifacts.
