It takes a substantial amount of money, expensive equipment, a group of technicians and an organization capable of obtaining materials secretly to produce most weapons of mass destruction, such as chemical, biological and nuclear weapons. One reasonably capable person with a laptop computer can "crash" critical information systems throughout the world, however.
Last week, U.S. and South Korean officials confirmed a new "cyberattack" on such systems in our countries. Among targets were the Pentagon, the White House, the New York Stock Exchange and the Treasury Department. The hackers were successful enough to disable the Treasury Department Web site for two days.
North Korea or North Korean sympathizers have been blamed for the attack.
The United States needs to put more effort into building our defense against such attacks, and attacking and stopping those who mount these cyberattacks.
