Detailed Introduction to Threat Model Companion

Threat Model Companion is a specialized tool designed to assist in the comprehensive analysis and visualization of security threats within various systems, particularly web applications. It leverages established threat modeling frameworks such as STRIDE and Adam Shostack's '4 question threat model' to provide users with a structured approach to identifying, assessing, and mitigating security risks. The tool is equipped with capabilities to create visualizations using Medusa.js, which enhances its utility in generating example attack trees and data flow diagrams (DFDs). For instance, in a scenario where a development team is assessing the security of a new web application, Threat Model Companion can be used to map out potential threats using STRIDE, then visualize these threats through attack trees and DFDs, allowing for a clear understanding of possible vulnerabilities and their implications.
