Virtual machines (VMs) must remove unneeded serial devices.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
| V-258725 | VMCH-80-000212 | SV-258725r933236_rule | CCI-000366 | medium |
| Description | ||||
| Ensure no device is connected to a virtual machine if it is not required. For example, floppy, serial, and parallel ports are rarely used for virtual machines in a data center environment, and CD/DVD drives are usually connected only temporarily during software installation. | ||||

Check Text (C-258725r933236_chk)
For each virtual machine do the following:
From the vSphere Client, right-click the Virtual Machine and go to "Edit Settings".
Review the VMs hardware and verify no serial devices exist.
or
From a PowerCLI command prompt while connected to the ESXi host or vCenter server, run the following command:
Get-VM | Where {$_.ExtensionData.Config.Hardware.Device.DeviceInfo.Label -match "serial"}
If a virtual machine has a serial device present, this is a finding.
Fix Text (F-62374r933235_fix)
The VM must be powered off to remove a serial device.
For each virtual machine do the following:
From the vSphere Client, right-click the Virtual Machine and go to "Edit Settings".
Select the serial device, click the circled "X" to remove it, and click "OK".
