What is meant by "threat modeling" in software development?

Threat modeling in software development refers to the systematic process of identifying, assessing, and prioritizing potential threats to a system or application. This method involves analyzing various aspects of the software, including its architecture, functionality, and the data it handles, to recognize vulnerabilities that could be exploited by attackers.

By conducting threat modeling, developers and security professionals can better understand the potential risks their software faces. This understanding enables them to prioritize threats based on factors such as the likelihood of occurrence and the possible impact on the system and its users. As a result, the development team can implement appropriate security measures and design decisions early in the development lifecycle, ultimately leading to a more secure product.

This practice not only enhances the overall security posture of the software but also helps in making informed decisions about resource allocation for addressing specific threats. Adopting threat modeling as part of the software development process is essential in proactively managing security risks instead of reacting to incidents after they occur.
