Dynamic application security testing (DAST) is considered "black-box" testing and begins with no inside knowledge of the application or its configurations. Everything about it must be discovered during its testing. As with most types of testing, dynamic application security testing (DAST) involves probing, scanning, and a discovery process for system information.
