Software security issues have been a major concern to the cyberspace community; therefore, a great deal of research on security testing has been performed, and various security testing techniques have been developed. A security process that is integrated into the application development cycle is required for creating a secure system. A part of this process is to create a threat profile for an application. The present project explains this process as a case study for analyzing a web application using Threat Modeling. This analysis can be used in the security testing approach that derives test cases from design level artifacts.
