PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and path sanitization that prevent absolute path traversal.

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

Security testing in development can detect absolute path traversal via static analysis and fuzzing.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes input validation and path-handling requirements that reduce absolute path traversal risk.

A.8.26 Application security requirements partial match
prevents

Application security requirements typically mandate controls against path traversal in file-access functions.

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

Secure architecture principles call for canonicalization and sandboxing that limit absolute path traversal.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require neutralization of absolute path sequences in pathname construction.

A.8.3 Information access restriction partial match
mitigates

Information access restriction limits which files can be reached but does not address the path-construction flaw itself.
