Security issue concern

Thank you Kevin

This is an enormous question. much deeper than it appears on the surface.

Start with how are you protecting the files that are on regular windows shares? If you have a system in place for that you might be able to adapt it to your projectwise. if you don't have that and you want to use projectwise as a way to accomplish that:

"a user" - what user, just anybody in the company or a user that actually has to do work on the files? For the first, if they don't need access to projectwise, don't give to them. Additionally make sure your security is tightened down so users don't get access to files they shouldn't.

"take data out" - take data out by what methods? Cloud service file transfer services (dropbox, send.firefox.com, etc...)? USB thumbdrive? Do they have a laptop they can just walk out with? What if they take pictures of the screen with their phone?

Number 1 is don't give access to files users don't need access to. If user needs access to the file and they open the file - the file is copied to the local machine. If they scour hard enough they can find that file on the local machine. At this point it's a matter of denying them ways to get that data off the local computer. Blocking cloud service file transfers, locking down USB ports, policies against cameras in the workplace, no laptops, etc....

Without deciding on your paranoia level this question really can't be answered.
