A protection system for a data processing device has a scanning device for scanning a data exchange through a physical data connection connecting an internal data processing device to an external data network. A transfer component is connected to the physical data connection for transferring data. A blocking device is provided for blocking the physical data connection when activated. When activated, the blocking device acts in such a way on the transfer component that no data can be transferred through the transfer component.
