Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and code analysis directly locate calls to unsafe functions.

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

Documented standards and tools can explicitly disallow dangerous functions during development.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles can mandate safe APIs and ban dangerous functions at design time.

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 require avoiding or safely wrapping dangerous functions during development.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing can surface instances of dangerous functions but does not prevent their introduction.

A.6.3 Information security awareness, education and training partial match
prevents

Developer security awareness training can teach safe alternatives to risky functions.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC processes include code review and static analysis that can detect use of risky functions.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly ban or restrict dangerous functions such as strcpy, gets, or system.

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

Controlled software installation reduces exposure to unsafe third-party libraries that may contain dangerous calls.
