Jacob is performing a Static Application Security Testing (SAST). SAST involves inspecting the source code to find security vulnerabilities that could be exploited by attackers. It is a white-box testing method where the tester has knowledge of the system architecture and source code. SAST tools analyze the code for patterns that may indicate security issues, such as input validation errors, insecure dependencies, and more.

References:For specific references, please consult the EC-Council Application Security Engineer (CASE) JAVA related courses and study guides. These resources will provide detailed information on SAST and its methodologies as per the EC-Council’s standards and guidelines. My response is based on the general knowledge of application security practices up to the year 2021.
