After you configure integration between Kaspersky Next XDR Expert and Kaspersky Anti Targeted Attack Platform, you can perform response actions on a device or with a file hash in one of the following ways:

• From the alert or incident details
• From the device details
• From the event details

  This option is available for the Add prevention rule response action. 

• From an investigation graph

You can also configure the response action to run automatically when creating or editing a playbook.

To perform response actions through Kaspersky Anti Targeted Attack Platform, you must have one of the following XDR roles: Main administrator, Tenant administrator, Junior analyst, Tier 1 analyst, Tier 2 analyst.
