Configuring Sophos XG 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.

               Let us know if you find the above overview useful.

Connecting a Sophos XG Firewall Connector

To connect a Sophos XG firewall:

1. Create IP host groups and add them to firewall deny rules in Sophos XG
   1. Enable API configuration

      • Check Enable

      • In Allowed IP address, enter the source IP address of the device making the API calls, for example, the local Stellar Cyber sensor IP address

2. Add the connector in Stellar Cyber
3. Test the connector

Adding the Connector in Stellar Cyber

To add a new Sophos XG 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 Sophos XG Firewall 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 the User Name to log in to the firewall.

12. Enter the Password for that user.

13. Enter the Device IP Address.

14. Enter the Source IP Group to which to add the IP address.

15. Enter the Destination IP Group to which to add the IP address.

16. Enter the Device Port. The default Admin console HTTPS port configured in the Sophos XG firewall is 4444.

17. Click Next. The final confirmation tab appears.

    

18. 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.
