Which testing method requires access to source code and performs a detailed examination of logical paths?

Whitebox testing is a method that requires access to the source code of an application to perform its assessments. This approach allows security professionals to analyze the internal workings of the software, including its logic, control flow, and data paths. By examining the source code in detail, testers can identify vulnerabilities, logic errors, and potential security flaws that may not be visible during other forms of testing.

This testing method is particularly effective because it provides insights into how the software functions at a granular level, enabling testers to simulate various scenarios and detect issues that could lead to security breaches. Since it involves a comprehensive review of the code, testers can ensure that every logical path is evaluated, which is critical for identifying and fixing security vulnerabilities early in the software development process.
