Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly blocks external control of file names/paths by validating untrusted input before it is used to access filesystem resources.

AC-3 Access Enforcement good match
prevent

Enforces authorization checks on every file/path access attempt, preventing a low-privileged remote user from reaching unauthorized objects.

AC-6 Least Privilege partial match
prevent

Limits the set of files and directories a low-privileged account can reference, reducing the impact surface of a path-control exploit.

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 full match
prevents

Secure SDLC practices include input validation and path sanitization that eliminate this weakness.

PR.AA-05 mostly match
prevents

Least-privilege file authorization directly limits damage from externally controlled paths.

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
detects

Security testing can detect path-traversal issues but does not itself implement preventive controls.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and path-handling controls that directly prevent external file/path manipulation.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against untrusted input influencing file operations.

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

Secure architecture principles discourage unsafe path construction but do not prescribe concrete file-name controls.

A.8.28 Secure coding partial match
prevents

Secure coding standards require canonicalization, allow-listing, and bounds checks on file paths, directly eliminating CWE-73.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits which files can be reached, indirectly reducing impact of path manipulation.
