| From the vSphere Client, go to Hosts and Clusters. |
Select the ESXi Host >> Configure >> Networking >> VMkernel adapters.
Review each VMkernel adapter that is used for management traffic and view the "Enabled services".
Review the VLAN associated with each VMkernel that is used for management traffic. Verify with the system administrator that they are dedicated for that purpose and are logically separated from other functions.
If any services other than "Management" are enabled on the Management VMkernel adapter, this is a finding.
If the network segment is accessible, except to networks where other management-related entities are located such as vCenter, this is a finding.
If there are any other systems or devices such as VMs on the ESXi management segment, this is a finding.
