The ability to uninstall the Tanium Client service must be disabled on all managed clients.

An XCCDF Rule

Description

<VulnDiscussion>By default, end users have the ability to uninstall software on their clients. In the event the Tanium Client software is uninstalled, the Tanium Server is unable to manage the client and must redeploy to the client. Preventing the software from being displayed in the client's Add/Remove Programs will lessen the risk of the software being uninstalled by non-Tanium system administrators.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
