Description
Copy and paste operations are disabled by default; however, by explicitly disabling this feature it will enable audit controls to check that this setting is correct. Copy, paste, drag and drop, or GUI copy/paste operations between the guest OS and the remote console could provide the means for an attacker to compromise the VM.
