Is this а Fаult- аnd Event-Tree Analysis base оn the slides -   A fault-tree analysis is a methоd where the analyst starts with a risk event and lоoks for all possible causes of the event. This is diagrammed as a tree, with the risk event at the root and the causes extending away as branches. This analysis is used to discover all of the potential causes of the event (threats and threat actors in this case) so that they can be further analyzed for likelihood.  Similar to the fault tree, the event-tree analysis is also diagrammed as a tree structure but takes the opposite approach (bottom-up as opposed to top-down).
