Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation partial match

Input validation directly stops invalid characters from being accepted in identifiers and tag/URI contexts.

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 proper input neutralization and validation to prevent identifier-handling flaws.

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 the weakness but does not itself implement the neutralization controls.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and sanitization that directly prevents improper neutralization of invalid characters in identifiers.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for validation of all inputs including identifiers, mitigating this weakness.

A.8.28 Secure coding partial match
prevents

Secure coding standards require proper neutralization of invalid characters in tag names, URIs and identifiers, directly addressing CWE-86.
