Technical Tip: Disabling the Microsoft Office Active Clipboard

Microsoft Office 2010 and later provides an Active Clipboard feature which allows for copying and pasting data between Office applications without using the system clipboard. The Reveal Agent is unable to prevent this copying.

FortiDLP recommends disabling this functionality via the Windows Registry to prevent the copying of sensitive content.

Method:

NextDLP recommends backing up the registry in line with Microsoft's documentation before editing.

1. Select Start, selectRun, type Regedit in the Open box, and then select 'OK'.
2. Locate and then select the following registry subkey:
   
   

HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Common\General

Note: 

xx.0 corresponds to the current Office version, e.g 16.0 = Office 2016.

1. On the Edit menu, point to New, and then select DWORD Value.
2. Type AcbControl, and then press Enter.
3. In the Details pane, 'right-click' AcbControl, and then select 'Modify'.
4. In the Value data box, type either decimal 2147483648 or hexadecimal 80000000, and then select 'OK'.
5. Exit Registry Editor.
