The ESXi host when using Host Profiles and/or Auto Deploy must use the vSphere Authentication Proxy to protect passwords when adding themselves to Active Directory.

Description
If a host is configured to join an Active Directory domain using Host Profiles and/or Auto Deploy, the Active Directory credentials are saved in the profile and are transmitted over the network. To avoid having to save Active Directory credentials in the Host Profile and to avoid transmitting Active Directory credentials over the network, use the vSphere Authentication Proxy.

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-258795r959010_chk)

For environments that do not use vCenter server to manage ESXi, this is not applicable. If the organization is not using Host Profiles to join Active Directory, this is not applicable. From the vSphere Client, go to Home >> Policies and Profiles >> Host Profiles. Click a Host Profile >> Configure >> Security and Services >> Security Settings >> Authentication Configuration >> Active Directory Configuration >> Join Domain Method. If the method used to join hosts to a domain is not set to "Use vSphere Authentication Proxy to add the host to domain", this is a finding. or From a PowerCLI command prompt while connected to vCenter, run the following command: Get-VMHost | Select Name, ` @{N="HostProfile";E={$_ | Get-VMHostProfile}}, ` @{N="JoinADEnabled";E={($_ | Get-VmHostProfile).ExtensionData.Config.ApplyProfile.Authentication.ActiveDirectory.Enabled}}, ` @{N="JoinDomainMethod";E={(($_ | Get-VMHostProfile).ExtensionData.Config.ApplyProfile.Authentication.ActiveDirectory | Select -ExpandProperty Policy | Where {$_.Id -eq "JoinDomainMethodPolicy"}).Policyoption.Id}} If "JoinADEnabled" is "True" and "JoinDomainMethod" is not "FixedCAMConfigOption", this is a finding.

From the vSphere Client, go to Home >> Policies and Profiles >> Host Profiles. Click a Host Profile >> Configure >> Security and Services >> Security Settings >> Authentication Configuration >> Active Directory Configuration. Click "Edit Host Profile...". Set the "Join Domain Method" to "Use vSphere Authentication Proxy to add the host to domain" and provide the IP address of the vSphere Authentication Proxy server. Click "Save".
