Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation partial match

Input validation directly requires checking and neutralizing user-supplied encoded URI schemes before they can be rendered or executed.

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 output encoding to prevent URI-based injection flaws.

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 in development and acceptance will detect URI-scheme injection flaws before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle incorporates the above controls, providing indirect but systematic coverage.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for input validation and output encoding that directly prevent URI-scheme injection.

A.8.28 Secure coding partial match
prevents

Secure coding standards mandate proper neutralization of encoded URI schemes, eliminating the root cause of CWE-84.
