Prevent users from copying files

Hey guys,

I want to prevent users from copying files from the network drives to an external HDD or Flash drive.

Also can i tell if someone has already done this within the last 30-60 days?

Thanks!

You can use group policy to block various types of removable media from being used. But it'll block reads as well as writes. There is no native way to block just copying or even audit copying. For that you'll need to deploy some sort of rights management solution, and most of those are not cheap.

There is no good native way to do that either.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Actually, I've used group policy to block access to USB drives and block writes to optical media.  This doesn't stop DropBox, OneDrive, emailing of files.  

You could use a third party product like DriveLock which can do things similarly through group policy.  It can tell you when things have been copied (as I recall it does this through creating a second copy for administrative purposes so you know it's been done).

Fortunately, the GPOs differ between blocking reads and writes, Cliff. There's also a native way to audit removable media thoroughly starting with server 2012 and win8: http://technet.microsoft.com/en-us/library/jj574128.aspx

But you won't be able to see what happened in the past before you will have setup auditing options.

What do you recommend 3rd party wise to audit and prevent users from copying files?

McKnifeCommented:
Did you look at the built-in options already (I linked those)? Only if those don't fit your needs would i recommend to look for 3rd party auditing applications.
