The Tanium Application Server console must be configured to initiate a session lock after a 15-minute period of inactivity.

An XCCDF Rule

Description

<VulnDiscussion>When multifactor authentication is enabled, the Tanium Console will initiate a session lock based on the ActivClient or other smartcard software. By initiating the session lock, the console will be locked and not allow unauthorized access by anyone other than the original user. Although this setting does not apply when multifactor authentication is enabled, it should be explicitly disabled in the event multifactor authentication is ever broken or removed.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
