Security Basics: Preventing Copy/ Paste

[amandeep Singh <amandeep1 () hotpop com>]

Hi All,

I was wondering if there is any way by which we can prevent the copy/paste option from a system., or we could restrict 
it for some authorized people. 

In an security environment, if a system has been compromised or if an authorized user tries to leak some confidencial 
info through copy/paste to some USB drive. Is there any way to prevent this?
