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

Security testing in development can detect unquoted search-path issues before deployment.

A.8.19 Installation of software on operational systems partial match
degrades

Enforcing controlled software installation can prevent unquoted search-path elements in executables and scripts.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle practices include input validation and path handling that reduce unquoted search-path weaknesses.

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

Secure system architecture and engineering principles require safe path construction and quoting conventions.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly mandate quoting search paths and avoiding unsafe path construction.

A.8.32 Change management partial match
degrades

Change-management processes can enforce review of path-handling changes that might introduce unquoted elements.
