Threat Scenarios
A Threat Scenario describes a high-level threat that could affect a vehicle component or system. It is the root node of the TARA graph: one scenario can be linked to many Threats, many Damage Scenarios (what harm results), and many Attack Paths (how the threat is realized).
List View
Open Risk Manager → Libraries → Threat Library, then select the Threat Scenarios tab.
The table shows each scenario’s ID (its auto-generated TS-xxx reference), Title, Threats (as chips), Damage Scenarios (reference chips), Attack Paths (reference chips), and an Actions column. Only the ID cell is a link — click it to open the detail page.
- Create — click New in the toolbar. The New Threat Scenario dialog has a required Title plus optional Description, Threats (multi-select), Damage Scenarios (multi-select), Attack Paths (multi-select), and Keywords (multi-select). The reference is auto-generated — there is no reference input.
- Delete — click the delete icon in the Actions column; a confirmation dialog appears before the scenario is permanently removed.
