They may be also used to illegally copy confidential data. Floppy drives are rarely needed when users have reliable networked printers, file servers and email available. Removable hard disks and floppy disks should only be used where absolutely necessary. Avoid copying data to floppy disk. Floppy drives should be removed, unless the internal network is considered too insecure.
Removable disks can be more secure than using a network server since all data is kept locally.
In this case disks must be kept carefully in a locked safe. Confidential data should be encrypted. This is preferable to the use of removable disks since regular backups will be made. All disks should be classified and the classification level should be written on the disks. Consider protecting media against Electromagnetic Pulses.
