Threats Manager Studio (TMS) includes multiple ways to associate Threat Events. One of them is provided within the Diagram tool: the Threat Types palette.
This palette is available in the Diagram tool and allows searching for Threat Types, by specifying some text to be searched in its text fields. You can then drag & drop the identified Threat Type to Entities or Flows, to associate it by creating a Threat Event.
Threat Types have a special field called “Keywords”, belonging to Property Schema “Threats”. If you put some text there, it will also be used for searching for Threats Types within the Threat Types palette. Being more specific, the Threat Types where the searched text is present among the Keywords are listed first.
