Wallarm Cloud IP addresses

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

US CloudEU Cloud

35.235.66.155
34.102.90.100
34.94.156.115
35.235.115.105
34.94.85.217
34.94.51.234
34.102.59.122

إعداد التنبيهات الإضافية¶

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
What is not counted
- For attacks:
  - The experimental attacks based on the custom regular expressions.
- For hits:
  - The experimental hits based on the custom regular expressions.
  - Hits not saved in the sample.
Changes in API took place
IP address was denylisted
New rogue API (shadow, orphan, zombie) was detected
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.

تنظيم الأحداث في لوحة تحكم¶

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.

To install the Wallarm application for Splunk:

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

تعطيل وحذف التكامل¶

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.

عدم توفر النظام وأخطاء في معايير التكامل¶

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.
