Configuring F5 Silverline 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 an F5 Silverline Connector

To add a new F5 Silverline firewall connector:

Enable API access
Add the connector in Stellar Cyber
Test the connector

Enabling API Access

On your F5 Silverline firewall, to enable API access:

Create an API token by navigating to Config | API Tokens.

The Block IP action adds an IP address to the deny list. The Unblock IP action removes the IP address from the deny list. To find blocked IP addresses, navigate to Config | IP Management | IP Denylists.

Adding the Connector in Stellar Cyber

To add a new F5 Silverline firewall connector in Stellar Cyber:

Log in to Stellar Cyber.
Click System | Integration | Connectors. The Connector Overview appears.
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.
Choose Firewall from the Category drop-down.
Choose F5 Silverline from the Type drop-down.
For this connector, the supported Function is Respond, which is enabled already.
Enter a Name.

This field does not accept multibyte characters.
Choose a Tenant Name. The Interflow records created by this connector include this tenant name.
Choose the device on which to run the connector.
Click Next. The Configuration tab appears.

The asterisk (*) indicates a required field.
Enter the API Token. This is the token for the F5 Silverline API.
Click Next. The final confirmation tab appears.
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.

Click System | Integrations | Connectors. The Connector Overview appears.
Locate the connector that you added, or modified, or that you want to test.
Click Test at the right side of that row. The test runs immediately.

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

Stellar Cyber conducts a basic connectivity test for the connector and reports a success or failure result. A successful test indicates that you entered all of the connector information correctly.

To aid troubleshooting your connector, the dialog remains open until you explicitly close it by using the X button. If the test fails, you can select the button from the same row to review and correct issues.

The connector status is updated every five (5) minutes. A successful test clears the connector status, but if issues persist, the status reverts to failed after a minute.

Repeat the test as needed.
