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

Setting up additional alerts

Besides the notifications you have already set up through the integration card, Wallarm triggers allow you to select additional events for notifications:

  • Number of attacks, hits or incidents per time interval (day, hour, etc.) exceeds the set number

  • Changes in API took place

  • IP address was denylisted

  • New user was added to the company account

For condition detailing, you can add one or more filters. As soon, as condition and filters are set, select the integration through which the selected alert should be sent. You can select several integrations simultaneously.

Choosing an integration

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.

Disabling and deleting an integration

You can delete or temporarily disable the integration. While deleting stops sending notificatioins and completely deletes all configuration, disabling just stops sending notifications which you can at any moment re-enable with the same settings.

If for the integration the System related events are selected to trigger notifications, Wallarm will notify about both of these actions.

System unavailability and incorrect integration parameters

Notifications to the system are sent via requests. If the system is unavailable or integration parameters are configured incorrectly, the error code is returned in the response to the request.

If the system responds to Wallarm request with any code other than 2xx, Wallarm resends the request with the interval until the 2xx code is received:

  • The first cycle intervals: 1, 3, 5, 10, 10 seconds

  • The second cycle intervals: 0, 1, 3, 5, 30 seconds

  • The third cycle intervals: 1, 1, 3, 5, 10, 30 minutes

If the percentage of unsuccessful requests reaches 60% in 12 hours, the integration is automatically disabled. If you receive system notifications, you will get a message about automatically disabled integration.
