I have a client with an in-house Windows 2008 server that stores proprietary documents (Word, Excel, PPT, PDF etc.) and videos (demos and training materials) of CAD/CAM software.
They have a mobile workforce (marketing & sales) that travels around the country and connects to the server using USB modems (dongles or data cards). When visiting prospective clients, they connect to the in-house server remotely and pull up the relevant documents and videos to show to the prospects.
The client wants to secure the remote connectivity using VPN, which is not too difficult. However, the client also wants to ensure that none of these proprietary documents or videos can be downloaded or saved locally by any member of the travelling workforce.
Is there a way to do this at all? After all, if they are able to open the application that's needed to open the file/video, they would obviously have the ability to access that application's File menu, which would let them save or download the file to their system?
A bit stumped here and would be thankful for any pointers.
Someone told me to implement a File Server on the Windows Server and then make that accessible only through the Web. Then, the VPN could be configured to access the File Server only through the Web, which would prevent the downloading and saving of files and only enable opening or playback. I am not sure this makes sense to me.
Thanks in advance.
