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.

   

   The asterisk (*) indicates a required field.

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.

10. Click Next. The Configuration tab appears.

    

    The asterisk (*) indicates a required field.

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.

    The password should not include non-ASCII special characters.

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).

For connectors running on a sensor, Stellar Cyber recommends that you allow 30-60 seconds for new or modified configuration details to be propagated to the sensor before performing a test.

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.
