Title

The Tanium application must limit the bandwidth used in communicating with endpoints to prevent a denial-of-service (DoS) condition at the server. (Cat II impact)

Discussion

DoS is a condition when a resource is not available for legitimate users. When this occurs, the organization either cannot accomplish its mission or must operate at degraded capacity. This requirement addresses the configuration of applications to mitigate the impact of DoS attacks that have occurred or are ongoing on application availability. For each application, known and potential DoS attacks must be identified and solutions for each type implemented. A variety of technologies exist to limit or, in some cases, eliminate the effects of DoS attacks (e.g., limiting processes or restricting the number of sessions the application opens at one time). Employing increased capacity and bandwidth, combined with service redundancy, may reduce the susceptibility to some DoS attacks.

Check Content

1. Using a web browser on a system that has connectivity to the Tanium application, access the Tanium application web user interface (UI) and log on with multifactor authentication. 2. Click "Administration" on the top navigation banner. 3. Under "Configuration", select "Bandwidth Throttles". 4. Work with the Tanium administrator to confirm settings. If settings are not based on organization needs, this is a finding. For more information, refer to https://docs.tanium.com/platform_user/platform_user/console_bandwidth_throttling.html.
