Vulnerability discussion

Ensure that 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 datacenter environment, and CD/DVD drives are usually connected only temporarily during software installation.

Check content

From the vSphere Client select the Virtual Machine right click and go to Edit Settings. Review the VMs hardware and verify no USB devices exist. or From a PowerCLI command prompt while connected to the ESXi host or vCenter server run the following commands: Get-VM | Where {$_.ExtensionData.Config.Hardware.Device.DeviceInfo.Label -match "usb"} Get-VM | Get-UsbDevice If a virtual machine has any USB devices or USB controllers present, this is a finding.

Fix text

From the vSphere Client select the Virtual Machine right click and go to Edit Settings. Select the USB controller and click remove then OK. or From a PowerCLI command prompt while connected to the ESXi host or vCenter server run the following command: Get-VM "VM Name" | Get-USBDevice | Remove-USBDevice Note: This will not remove the USB controller just any connected devices.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.
