How to prevent Ransomware on corporate network?

Hi All,

In the past couple of months, we have been hit with the ransomeware virus 3 times.  Luck for us we have timely backups that allow us to restore shared network drives; however, I'm looking for a way around this.  Since we are a completely virtual environment, I don't care about a person's individual VM getting blown up- we can always recreate that.  What I do care about is our network shares.  I've been trying to research ways to prevent the encryption of those files.  One idea I had was requiring user authentication to the shared drives, like every 10 minutes if they have to access it.  Then I'm limiting the window whereby I could have an infection.  Has anyone come up with any solutions to prevent this from happening?

Any help would be greatly appreciated.
