Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings partial match

Documented configuration settings externalize security-critical values so they are not hard-coded in source.

SA-15 Development Process, Standards, and Tools partial match

Requiring a documented development process and standards can mandate use of symbolic names for constants.

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.PS-06 mostly match
prevents

Secure SDLC practices directly enforce use of named constants and configurable values for security parameters.

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.8.25 Secure development life cycle partial match
prevents

Secure SDLC processes can catch hard-coded constants during reviews and testing.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly prohibit hard-coded security constants.

A.8.32 Change management none match
none

Change management may detect constant changes but does not prevent their initial hard-coding.

A.8.9 Configuration management none match
none

Configuration management can externalize constants but does not directly address coding practice.
