Threat Information

After a model is drawn, you will be presented with a list of threats. You’ll find the list of threats organized in a grid that shows for each threat:

Threat Title

Threat (STRIDE) Category




Last modified

Threat State

Threat Priority

Each threat will have a Description fieldwhich will have content for every auto-generated threat and a Justification field in which mitigation information can be entered by the user.

For newly generated threat models, the setting for auto-generation threat mode is enabled by default. For migrated threat models created with Threat Modeling Tool 3.1.8, the auto-generation threat mode is set to off. To turn it on go to Settings and select Enable Threat Generation. Each threat will have options that enable you to manage the identified threats. By default, the state of all newly generated threats is Not Started.

Threats are generated using STRIDE per interaction. An interaction is defined by two elements connected by a data flow, and may include a boundary. If an element is marked Out of Scope threats will still be auto-generated for that interaction but the element itself will have visual feedback that is marked Out of Scope. You can also add a user-defined or custom threat by right-clicking on the desired data flow in the interaction and selecting Add User-defined Threat. When you do so you’ll find your custom threat at the end of the existing threat list. Threat priority is by default set to High. As applicable, it can be changed to Medium or Low.
