Threat modeling is an essential process in the secure development lifecycle that is typically performed during the design phase. This process involves identifying, predicting, and defining potential threats, as well as determining the likelihood and impact of these threats on the application. By conducting threat modeling in the design phase, developers and security teams can proactively address security issues and integrate necessary countermeasures before the coding begins. This approach helps to minimize vulnerabilities and ensures that security considerations are embedded into the application from the early stages of development.
