Use the AlienApp for Palo Alto Networks to access the Palo Alto Networks response actionsIn USM Anywhere you can execute an action from alarms, events, and vulnerabilities to run a scan, get forensic information, or execute a response for a configured AlienApp., which enable you to quickly respond to threats identified by USM Anywhere. You can create response action rules in USM Anywhere that automatically trigger when alarmsAlarms provide notification of an event or sequence of events that require attention or investigation. or eventsAny traffic or data exchange detected by AlienVault products through a Sensor, or through external devices such as a firewall. match the criteria that you specify. For example, you might create a rule where USM Anywhere automatically sends the host information for malware infections that it identifies to the connected Palo Alto Networks device as a request to tag the host for policy enforcement.

Note: Before creating a response action rule or launching a Palo Alto Networks action, the AlienApp for Palo Alto Networks must be enabled and configured in your USM Anywhere environment. For more information, see Configuring the AlienApp for Palo Alto Networks .

After you create a rule, new events or alarms that match the rule will trigger the Palo Alto Networks action to tag to the associated source or the destination host. The rule does not trigger for your existing alarms or events.

You can create a new rule in one of two ways.

  • From an Applied Response Action — You can automatically create a rule using the response action that you apply to an existing alarm or event. This makes it easy to set the matching conditions for the rule based on the existing item and use the same settings that you applied to that item.

    In the confirmation dialog, click Create rule for similar alarms or Create rule for similar events.

  • From the Rules page — The Rules page provides access to all of your orchestration rules. The Orchestration Rules list includes suppression rules, alarm 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/disable rules. For more information about managing orchestration rules, see Orchestration Rules.

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

    You can launch an action to tag the destination host or source for an alarm or an event.

  3. Enter the Palo Alto Networks Tag Name that you want to apply to the host.

    Set options to launch the Palo Alto Networks action for the rule

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

    • If you create the rule from an applied action, this section provides suggested property/value pairs from the selected alarm or event that you can use as conditions for the rule. Click the Delete () icon for items that you do not want to include in the matching conditions. You can also add other conditions that are not suggested.
    • If you create the rule from the Rules page, you must use the Add Condition and Add Group functions to define the property/value pairs that you want to use as conditions for the rule.

    Click the More... link at the bottom of the dialog to display the optional multiple occurrence and window length parameters.
