The ESXi host must configure a session timeout for the vSphere API.

Description
The vSphere API (VIM) allows for remote, programmatic administration of the ESXi host. Authenticated API sessions are no different from a risk perspective than authenticated UI sessions and they need similar protections. One of these protections is a basic inactivity timeout, after which the session will be invalidated and reauthentication will be required by the application accessing the API. This is set to 30 seconds by default but can be disabled, thus leaving API sessions open indefinitely. The 30 second default must be verified and maintained.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-258781r933404_chk)

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "Config.HostAgent.vmacore.soap.sessionTimeout" value and verify it is set to "30". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name Config.HostAgent.vmacore.soap.sessionTimeout If the "Config.HostAgent.vmacore.soap.sessionTimeout" setting is not set to "30", this is a finding.
