Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and code analysis can locate calls to known dangerous functions after they have been written.

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

Documented development standards and tools can explicitly prohibit or replace inherently dangerous functions.

SA-3 System Development Life Cycle partial match

An SDLC that incorporates security can embed rules against unsafe functions in coding and review phases.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can mandate avoidance of unsafe library functions during design and coding.

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 prohibit or replace inherently dangerous functions via coding standards, reviews, and tooling.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing can surface calls to unsafe functions but does not prevent their introduction.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC processes include code review and static analysis that can detect dangerous function usage.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly ban or restrict inherently dangerous functions.

A.8.19 Installation of software on operational systems none match
none

Controlled software installation reduces exposure to unsafe third-party code containing dangerous functions.
