Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-28 Protection of Information at Rest good match

Requiring confidentiality protection of information at rest directly stops passwords from being stored in plaintext.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-01 mostly match
prevents

Encryption and hashing of data-at-rest directly prevent plaintext password storage in files.

PR.AA-01 partial match
prevents

Credential management practices normally include secure storage requirements for passwords.

PR.DS-10 partial match
prevents

Protecting data-in-use can limit exposure of passwords held in memory.

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.5.17 Authentication information full match
degrades

Directly requires secure handling and protection of authentication information, preventing plaintext password storage.

A.8.24 Use of cryptography mostly match
prevents

Requires use of cryptography to protect sensitive data such as passwords at rest.

A.8.28 Secure coding partial match
prevents

Secure coding practices would prevent developers from writing code that stores passwords in plaintext.

A.8.5 Secure authentication partial match
degrades

Mandates secure authentication mechanisms that inherently require hashed or encrypted credentials rather than plaintext.

A.8.10 Information deletion none match
mitigates

Requires secure deletion of sensitive information, indirectly reducing exposure of stored plaintext passwords.
