Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
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.
Encryption and hashing of data-at-rest directly prevent plaintext password storage in files.
Credential management practices normally include secure storage requirements for passwords.
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.
Directly requires secure handling and protection of authentication information, preventing plaintext password storage.
Requires use of cryptography to protect sensitive data such as passwords at rest.
Secure coding practices would prevent developers from writing code that stores passwords in plaintext.
Mandates secure authentication mechanisms that inherently require hashed or encrypted credentials rather than plaintext.
Requires secure deletion of sensitive information, indirectly reducing exposure of stored plaintext passwords.
