We are trying to lock down our Citrix environment. We have users with thumb drives that copy data up to servers via Citrix. We are fine with that. However, we want to prevent them from copying company data back down to the thumb drives. Is there any way to lock this down in Citrix? As far as I can tell, all local drives and thumb drives just show up as mapped drives with no way to define things as read only within Citrix. I'm sure there must be a solution!
