Whitebox Testing

 
 

White-box testing goes by several different names, including clear-box, open-box, auxiliary and logic-driven testing. It falls on the opposite end of the spectrum from black-box testing: penetration testers are given full access to source code, architecture documentation and so forth. The main challenge with white-box testing is sifting through the massive amount of data available to identify potential points of weakness, making it the most time-consuming type of penetration testing.

Unlike black-box and gray-box testing, white-box penetration testers are able to perform static code analysis, making familiarity with source code analyzers, debuggers and similar tools important for this type of testing. However, dynamic analysis tools and techniques are also important for white-box testers since static analysis can miss vulnerabilities introduced by misconfiguration of target systems.
White-box penetration testing provides a comprehensive assessment of both internal and external vulnerabilities, making it the best choice for calculation testing. The close relationship between white-box pentesters and developers provides a high level of system knowledge but may affect tester’s behaviors, since they operate based on knowledge not available to hackers.
