From: Tanium 7.x Application on TanOS Security Technical Implementation Guide (V2R2)
Description
<VulnDiscussion>It is important for information system owners to document authorized user groups for the Tanium application to avoid unauthorized access to systems. Misaligned implementation of user groups grants excessive access and results in potential compromise of "need-to-know" when it comes to information access.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
