Role Availability Read-Only Investigator Analyst Manager

You can create orchestration rules in USM Anywhere that automatically trigger a SentinelOne response action when events Any traffic or data exchange detected by LevelBlue products through a sensor or external devices such as a firewall. or alarms Alarms provide notification of an event or sequence of events that require attention or investigation., match the criteria that you specify. This way, you can automate the way you filter IP addresses into the policies within the SentinelOne UI.

After you create a rule, new events or alarms that match the rule conditions will trigger the SentinelOne response action to create a new incident. The rule does not trigger for existing events or alarms.

You can create a new rule as follows:

  • From the Rules page: The Rules page provides access to all of your orchestration rules. The Orchestration Rules list includes suppression rules, alarm rules, event rules, filtering rules, notification rules, and response action rules. You can create new rules using the specific matching conditions that you define, as well as edit, delete, and enable or disable rules. See Orchestration Rules for more information about managing orchestration rules.

    Go to Settings > Rules and select Response Action Rules on the left navigation panel. Then click Create Response Action Rule to define the new rule.

  • From the App: Go to the BlueApp for SentinelOne page and click the Rules tab. Click Create New Rule to define the new rule.

To define a new SentinelOne response action rule

  1. Enter a name for the rule.

  2. Select the App Action for the rule and specify the information for the SentinelOne incident.

    The SentinelOne parameters that you set will depend on which of the following actions you select:

    • Create a New Incident from an Alarm

      This is the default action if you create the rule after applying a SentinelOne response action to an alarm. Use this action to run a new SentinelOne rule for the addresses of a new alarm that satisfies the matching criteria.

    • Create a New Issue from Event-Based Orchestration

      Use this action to add information to the designated SentinelOne groups based on an incident for any event that satisfies the matching criteria.

  3. At the bottom of the dialog box, set the Rule Condition parameters to specify the criteria for a matching alarm or event to trigger the rule.
