Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation directly requires checking and filtering special elements in data received from upstream before further processing or forwarding.

Output filtering validates data sent downstream and can catch or correct unfiltered special elements prior to transmission.

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 sanitization and filtering of special elements before data passes downstream.

ID.RA-01 partial match
prevents

Identifying recorded vulnerabilities can surface missing input filters during code or configuration review.

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.

finds

Security testing can detect improper filtering but does not itself implement the filtering control.

prevents

Secure development life cycle mandates input validation and sanitization that directly prevents improper filtering of special elements.

prevents

Application security requirements explicitly call for input validation controls that mitigate improper special-element filtering.

prevents

Secure system architecture and engineering principles include defensive input handling that reduces the risk of unfiltered special elements.

prevents

Secure coding standards require proper filtering and encoding of special elements before downstream processing.
