Tanium must limit the bandwidth used in communicating with endpoints to prevent a denial-of-service (DoS) condition at the server.
Vulnerability 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
Access the Tanium Server interactively.
Log on with an account with administrative privileges to the server.
Access the server's registry by typing: regedit .
Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server.
Verify the existence of a DWORD "DownloadBytesPerSecondLimit" with a value matching what is in the system documentation.
If the DWORD "DownloadBytesPerSecondLimit" does not exist with the correct value, this is a finding.

Access the Tanium Server interactively.
Log on with an account with administrative privileges to the server.
Access the server's registry by typing: regedit .
Navigate to HKEY_LOCAL_MACHINE >> SOFTWARE >> Wow6432Node >> Tanium >> Tanium Server.
Add or modify the DWORD "DownloadBytesPerSecondLimit" to have a value consistent with the value found in the system documentation.
Pro Tips
Lavender hyperlinks in small type off to the right (of CSS
class id, if you view the page source) point to
globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header Accept:
text/turtle or
Accept: application/rdf+xml.
