Active Directory ESX Admin group membership must not be used when adding ESXi hosts to Active Directory.

Description
When adding ESXi hosts to Active Directory, all user/group accounts assigned to the Active Directory group \"ESX Admins\" will have full administrative access to the host. If this group is not controlled or known to the system administrators, it may be used for inappropriate access to the host. Therefore, the default group must be changed to a site-specific Active Directory group and membership must be severely restricted.

Who does this work

7 NICE work roles and 5 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-256404r958482_chk)

For systems that do not use Active Directory, this is not applicable. From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "Config.HostAgent.plugins.hostsvc.esxAdminsGroup" value and verify it is not set to "ESX Admins". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name Config.HostAgent.plugins.hostsvc.esxAdminsGroup If the "Config.HostAgent.plugins.hostsvc.esxAdminsGroup" key is set to "ESX Admins", this is a finding.

Fix Text (F-60022r885992_fix)

From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Click "Edit". Select the "Config.HostAgent.plugins.hostsvc.esxAdminsGroup" key and configure its value to an appropriate Active Directory group other than "ESX Admins". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name Config.HostAgent.plugins.hostsvc.esxAdminsGroup | Set-AdvancedSetting -Value <AD Group>
