CISA · Question #445

Which type of security testing is MOST efficient for finding hidden errors in software and facilitating source code optimization?

The correct answer is B. White box testing. White box testing leverages full access to the application’s source code and internal architecture, enabling testers to systematically uncover hidden logic errors, security flaws, and inefficiencies and to recommend code-level optimizations.
