Configuring Palo Alto Networks Firewall Connectors

You can connect Stellar Cyber to firewalls so that you can quickly and easily implement firewall rules on those firewalls from within Stellar Cyber, while you are threat hunting. You can configure firewall actions or manually trigger a firewall action from the event display. For either action you must already have your firewall connected.

Adding a Palo Alto Networks Firewall Connector

To add a new Palo Alto Networks firewall connector:

1. Create firewall rules
2. Add the connector in Stellar Cyber
3. Test the connector

Creating Firewall Rules

To trigger firewall actions from Stellar Cyber, you must already have firewall rules. To create Palo Alto firewall rules:

1. Create an address group called Stellar_src_group. You must include at least one IP address.

   

2. Create an address group called Stellar_dst_group. You must include at least one IP address.

3. Create an outbound deny policy with the following:

   

   • Name: Stellar_Outbound_Deny

   • Source:

     • Zone: Any

     • Address: Stellar_src_group

     • User: any

     • Device: any

   • Destination:

     • Zone: Any

     • Address: Any

     • User: any

     • Device: any

   • Application: any

   • Service: any

   • Action: DENY

4. Create an inbound deny policy with the following:

   

   • Name: Stellar_Inbound_Deny

   • Source:

     • Zone: Any

     • Address: any

     • User: any

     • Device: any

   • Destination:

     • Zone: Any

     • Address: Stellar_dst_group

     • User: any

     • Device: any

   • Application: any

   • Service: any

   • Action: DENY

5. Commit all of your changes.

   

You now have firewall rules that you can trigger from Stellar Cyber.

Adding the Connector in Stellar Cyber

With the firewall rules in place, you can add the Palo Alto Networks firewall connector in Stellar Cyber:

1. Log in to Stellar Cyber.

2. Click System | Integration | Connectors. The Connector Overview appears.

   

3. Click Create. The General tab of the Add Connector screen appears. The information on this tab cannot be changed after you add the connector.

   

4. Choose Firewall from the Category drop-down.

5. Choose Palo Alto Networks from the Type drop-down.

6. For this connector, the supported Function is Respond, which is enabled already.

7. Enter a Name.

   This field does not accept multibyte characters.

8. Choose a Tenant Name. The Interflow records created by this connector include this tenant name.

9. Choose the device on which to run the connector.

   • Certain connectors can be run on either a Sensor or a Data Processor. The available devices are displayed in the Run On menu. If you want to associate your collector with a sensor, you must have configured that sensor prior to configuring the connector or you will not be able to select it during initial configuration. If you select Data Processor, you will need to associate the connector with a Data Analyzer profile as a separate step. That step is not required for a sensor, which is configured with only one possible profile.

   • If the device you're connecting to is on premises, we recommend you run on the local sensor. If you're connecting to a cloud service, we recommend you run on the DP.

10. Click Next. The Configuration tab appears.

    

11. Enter a User Name with permissions to edit address groups and commit the changes to the firewall.

12. Enter the Password for that user name.

13. Enter the Device IP Address.

14. Enter the Device Port. The default is 443.

15. Enter the Source IP Group you created (for example, Stellar_src_group).

16. Enter the Destination IP Group you created (for example, Stellar_dst_group).

17. Enter the Virtual System Name. If the firewall is not configured to use multi-vsys, use vsys1.

18. Click Next. The final confirmation tab appears.

    

19. Click Submit.

The new firewall connector is immediately active.

Testing the Connector

When you add (or edit) a connector, we recommend that you run a test to validate the connectivity parameters you entered. (The test validates only the authentication / connectivity; it does not validate data flow).

1. Click System | Integrations | Connectors. The Connector Overview appears.

   

2. Locate the connector that you added, or modified, or that you want to test.

3. Click Test at the right side of that row. The test runs immediately.

   Note that you may run only one test at a time.
