You wouldn't leave your wallet laying on a park bench, would you? Yet many people do the electronic equivalent by assuming that their data is automatically secure. You probably have a spare tire in your car “just in case” and you lock the car doors in public garages. Do you do the same for your valuable personal and corporate information? As our information systems grow more complex and we rely more on the electronic storage and transfer of information - in everything from banking to medical records to library accounts - the risk of damage, loss, and even fraud increases dramatically.
