The ESXi host client must be configured with an idle session timeout.
An XCCDF Rule
Description
<VulnDiscussion>The ESXi host client is the UI served up by the host itself, outside of vCenter. It is accessed at https://<ESX FQDN>/ui. ESXi is not usually administered via this interface for long periods, and all users will be highly privileged. Implementing a mandatory session idle limit will ensure that orphaned, forgotten, or ignored sessions will be closed promptly.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
