Data loss prevention is a primary concern for the DoW. Positive control of data must be maintained at all times, and data must only be allowed to flow over channels that are provided for that explicit purpose and are monitored appropriately. By default, the Horizon Agent will allow file transfers from the client to the VDI desktop. This must be configured to be disabled in both directions.
Verify the "vdm_agent*.admx" templates have been added to the Active Directory Domain. Open the "Group Policy Management" MMC snap-in, then open the applicable GPO that is applying the Horizon settings to the VDI desktops or RDS hosts. Navigate to Computer Configuration >> Policies >> Administrative Templates >> Omnissa Horizon Agent Configuration >> Clipboard Redirection. Double-click the "Configure file transfer" setting. If "Configure file transfer" is not set to "Enabled", this is a finding. In the drop-down menu under "Configure file transfer", if "Disabled both upload and download" is not selected, this is a finding.
