Abstract
A method of a computer system controlling writing of data to a removable medium includes communicating a unique identification (ID) of the removable medium to the computer system, intercepting a write operation to the removable medium, communicating with a security server via a network interface and a network, sending the unique ID of the removable medium along with a list of data files being written, and determining if the data files are allowed to be written to the removable medium using the security server. The determination includes determining a security level of the data files, determining a security level of the removable medium based on the unique ID, determining if the security level of the data files is higher than the security level of the removable medium, and sending a message to the computer system via the network and instructing the computer system to allow or prevent writing the data files. The data files are allowed to be written to the removable medium if the security level of the data files is equal or lower than the security level of the removable medium. The data files are prevented from being written to the removable medium if the security level of the data fi…
