Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

SI-10 directly requires validation of inputs, which structurally prevents improper whitespace handling before data reaches downstream components.

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 neutralization to prevent whitespace issues.

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.8.28 Secure coding mostly match
prevents

Secure coding standards directly require proper input sanitization and neutralization of special elements like whitespace.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect whitespace handling issues but does not prevent them at the source.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes input validation and sanitization practices that can prevent improper whitespace handling.

A.8.26 Application security requirements partial match
prevents

Application security requirements typically mandate proper input validation and neutralization of special characters including whitespace.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture principles may indirectly support input handling but do not specifically address whitespace neutralization.
