Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly neutralizes '../' sequences in externally-supplied pathnames before they are resolved.

AC-3 Access Enforcement partial match

Enforced access authorizations can limit the damage even when path traversal succeeds.

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 validation and path sanitization that prevent ../ traversal.

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 require neutralizing ../ sequences and canonicalizing paths before file operations.

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

Security testing in development catches path-traversal flaws before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and path canonicalization that directly block ../ traversal.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against path traversal in file-handling functions.

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

Secure architecture principles reduce attack surface but do not prescribe the specific coding fix.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits which files can be reached, mitigating impact of traversal.
