Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly stops unneutralized special elements from reaching query logic.

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 block wildcard injection.

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 wildcard issues but does not itself implement neutralization controls.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and sanitization that directly prevents wildcard injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules for neutralizing special characters before downstream processing.

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

Secure architecture principles encourage safe handling of untrusted input but do not prescribe specific wildcard neutralization.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly require proper escaping or neutralization of wildcard and matching symbols.

A.8.30 Outsourced development partial match
prevents

Outsourced development agreements can require secure coding practices, indirectly mitigating the weakness.
