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

Security testing can detect uncontrolled search-path issues but does not prevent them by itself.

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

Restricting software installation reduces the chance that an attacker-controlled path element is introduced into the search path.

Secure system architecture and engineering principles require explicit control over search paths and resource locations.

A.8.28 Secure coding partial match
prevents

Secure coding practices directly address the use of fixed or controlled search paths that can be influenced by unintended actors.
