Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

SI-10 requires validity checks on information inputs, directly stopping missing or undefined parameters from being accepted.

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 input validation and correct parameter handling to avoid this weakness.

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 detect missing-parameter issues but does not prevent them at design time.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes input validation and parameter handling requirements that reduce improper parameter handling.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for validation of inputs and parameters, mitigating missing or undefined arguments.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address proper handling of function parameters and input validation.
