Information Warfare and Security

n recent years, information warfare has captured the attention of government officials, information security specialists, and curious onlookers.The term is used to cover a broad spectrum of activity but especially a scenario wherein information terrorists, using not much more than a keyboard and mouse, hack into a computer and cause planes to crash, unprecedented power blackouts to occur, or food supplies to be poisoned.The terrorists might tamper with computers that support banking and finance, perhaps causing stock markets to crash or economies to collapse.None of these disasters has occurred, but the concern is that they, and others like them, could happen, given the ease with which teenagers have been able to romp through computers with impunity--even those operated by the U.S. Department of Defense.
