Threat modeling is the primary security analysis task performed during the software design stage. Threat modeling is a structured activity for identifying and evaluating application threats and vulnerabilities. The security objectives, threats, and attacks modeling activities during the threat modeling are designed to help you find vulnerabilities in your application and the supporting architecture. You can use the identified vulnerabilities to help shape your design and direct and scope your security testing.

Threat modeling allows you to consider, document, and discuss the security implications of designs in the context of their planned operational environment and in a structured fashion. It also allows consideration of security issues at the component or application level. The threat modeling course will teach you to perform threat modeling through a series of workshops, where our trainer will guide you through the different stages of a practical threat model.
