Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires protection of sensitive information (including credentials) at rest, preventing plaintext storage under HADR configurations.

prevent

Enforces access control decisions to block authenticated users from retrieving sensitive data exposed by the HADR flaw.

prevent

Requires secure management and storage of authenticators, directly addressing the CWE-256 plaintext password weakness.

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.

degrades

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

prevents

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

prevents

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

degrades

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

none

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