A corporation wants to prevent its sensitive documents from being moved outside its controlled environment. Which measure focuses on detecting attempts and restricting these transfers?
Data loss prevention (DLP) identifies patterns of restricted information and prevents it from leaving controlled locations. DNS filtering blocks access to certain domains but does not address data content. Confidential file scanning can discover protected files but does not stop them from being sent elsewhere. Access logs monitoring provides activity records without restricting file movement.
