Creating Automated Response Playbooks

Procedure

1. Go to Workflow and Automation → Security Playbooks.
2. On the Playbooks tab, choose Add → Create playbook.
3. On the Playbook Settings panel, select the XDR detection type, specify a unique name for the playbook, and click Apply.
4. On the Trigger Settings panel, select Automatic or manual (executed from Workbench) or Manual (executed from Workbench) for the trigger type and click Apply.
   • Automatic or manual (executed from Workbench): Workbench alerts automatically trigger playbook execution. You can also manually trigger playbook execution from Workbench.
   • Manual (executed from Workbench): You need to manually trigger playbook execution from Workbench.
   For more information about how to trigger playbook execution from Workbench, see All Alerts and Alerts (Workbench Insights) in the Workbench documentation.
5. On the Target Settings panel, select and configure the Target for the playbook and click Apply.
   1. In the Severity drop-down menu, select the severity level of Workbench alerts that require further investigation.
   2. If you want playbook actions to trigger only for Workbench alerts associated with specific detection models, select Filter by detection models.
      1. Click Select Models.
      2. Select the detection models by which to filter Workbench alerts.

         Important The severity of your selected models must match the severity of the target settings, otherwise the playbook might fail to run.

         Tip You can use both predefined and custom detection models to filter Workbench alerts. Click Custom Models to select custom detection models.

      3. Click Move to Selected Detection Models.
      4. Click Save.
   3. If you want to set conditions based on the risk rating of highlighted objects in the Workbench alert, select Filter by highlighted object risk.
   4. If you want the playbook to open a case for the Workbench alert that meets the conditions, select Open a Workbench case, assign a maximum of 50 owners to the alert, and specify whether to automatically close the case when the playbook executes successfully.

      Note This feature is not available in all regions.

      Important Creating a case transfers all Workbench notes to the case. New notes can only be added to the case. Alerts already associated with a case in Workbench will not trigger a new case creation. Instead, the playbook will update the existing case with the execution status and execution results. The playbook will not assign new owners to the existing case that already has owners.

   5. Click Apply.
6. If you need to take actions when specific conditions are met, configure the Condition node.
   1. Click the add node () on the right of the Target node and click Condition.
   2. Create a condition setting by specifying the Parameter, Operator, and Value.

      Setting	Description
      Parameter	Specify one of the following options as the parameter: Endpoint name Endpoint type Highlighted object risk Note This option is available only when you select Filter by highlighted object risk in the Target node. IP address Important This is a pre-release sub-feature and is not part of the existing features of an official commercial or general release. Please review the Pre-release sub-feature disclaimer before using the sub-feature. Operating system Operating system
      Operator	IS: The condition is triggered if any of the values is matched IS NOT: The condition is triggered if none of the values is matched
      Value	Specify the parameter value. The values for Highlighted object risk are described as follows: Highly suspicious: The likelihood of a highlighted object being false positive is low Suspicious: The likelihood of a highlighted object being false positive is higher Unrated: Analysis result other than Highly suspicious and Suspicious For information about the values for IP address, see the alert details in the Workbench app.

   3. Click Apply.
   4. If you need to add more than one parallel Condition node, click the add node () on the right of the Target node.
   5. If you need to configure action settings for the Condition node, add an Action node by clicking the add node () on the right.
      For details, see Step 7.
   6. If you need to configure else-if conditions or else actions, add an Else-If Condition or Else Action node by clicking the add node () under the Condition node.
      For details, see Step 9.
7. Configure actions by adding an Action node.
   1. Click the add node () on the right of the Condition node and click Action.
   2. On the Action Settings panel, select Workbench alert and configure the automated response actions taken on the highly suspicious, suspicious and/or unrated objects.
      Response actions require that you have configured the supporting services. For more information, see Response Actions.

Users are not prevented from immediately signing back in the closed sessions or signing in new sessions. Force Password Reset: Signs the user out of all active application and browser sessions, and forces the user to create a new password during the next sign-in attempt
      Container actions	None: Takes no action for containers Isolate Container: Stops the spread of suspicious behavior within a container by isolating the containing prod from the environment Terminate Container: Stops suspicious behavior of containers within a pod by terminating the pod

8. Configure notification settings by adding the second Action node.
   1. Click the add node () on the right of the first Action node and click Action.
   2. On the Action Settings panel, specify how to notify recipients of the playbook results.

   5. If you require manual approval for sending playbook results, follow Step 7.d to configure the notification settings.

      Note This setting is available only to ticket notification action.

   6. Click Apply.
9. Configure Else-If Conditions or Else Actions if necessary.
   1. Click the add node () below the condition node and click Else-If Condition or Else Action.
   2. Configure a condition node by following Step 6, or configure an action node by following Step 7 or Step 8.

   Note The nodes that can be added by using an add node () vary depending on the preceding node. For example, an Action node can only be possibly followed by another Action node; a Condition node can be followed by an Action node or have an Else-If Condition or Else Action attached to it. When a condition is false, the playbook performs the Else Action or checks if its Else-If Condition is met. If the Else-If Condition is met, the playbook continues to perform the corresponding Else Action. Multiple Action nodes configured in a serial mode are taken sequentially.

10. Enable the playbook by toggling the Enable control on.
11. Click Save.
    The playbook appears on the Playbooks tab in the Security Playbooks app.
