Wallarm Cloud IP addresses

To provide Wallarm Cloud access to your system, you may need a list of its public IP addresses:

34.94.85.217
34.94.51.234

34.141.230.156
34.91.138.113

Getting events organized into a dashboard

To get Wallarm events organized into a ready-to-use dashboard in Splunk 9.0 or later, you can install the Wallarm application for Splunk.

This application provides you with a pre-configured dashboard that is automatically filled with the events received from Wallarm. In addition to that, the application enables you to proceed to detailed logs on each event and export the data from the dashboard.

Splunk dashboard

To install the Wallarm application for Splunk:

  1. In the Splunk UI ➝ Apps find the Wallarm API Security application.

  2. Click Install and input the Splunkbase credentials.

If some Wallarm events are already logged in Splunk, they will be displayed on the dashboard, as well as further events Wallarm will discover.

In addition, you can fully customize the ready-to-use dashboard, e.g. its view or search strings used to extract data from all Splunk records.

Testing integration

Integration testing allows checking configuration correctness, availability of the Wallarm Cloud, and the notification format. To test the integration, you can use the button Test integration when creating or editing the integration.

The integration is tested as follows:

  • Test notifications with the prefix [Test message] are sent to the selected system.

  • Test integrations are sent for all events available for the selected system. If the integration card includes 3 event types, the system will receive 3 test notifications.

    If the integration card includes the event type System related, an appropriate test notification includes details on the newly added user.

  • Test notifications include test data.

Test Splunk notification in the JSON format:

    summary:"[Test message] [Test partner(US)] New vulnerability detected",
    description:"Notification type: vuln

                New vulnerability was detected in your system.
