Default Asset Rules
Default Asset Rules let you define Asset Groups that are automatically applied to Injects based on a Scenario’s tags. Each Asset Rule consists of a Tag and list of Asset Groups
You can manage these rules in Settings → Customization.
When you create an Inject in a Scenario, if the Scenario has a tag matching one of the Asset Rules, the associated default Asset Groups are automatically applied to that Inject. When a Scenario is updated, if you add a tag matching one of the Asset Rules, a pop-up will appear asking if you want to apply those default Asset Groups to the existing Injects in the Scenario.
OpenCTI default rule
By default, a rule for the opencti tag is created. This tag is automatically applied to Scenarios generated from OpenCTI (see Generating Scenario from OpenCTI ). This default rule cannot be removed, and its tag cannot be modified.
