U.S. faces threat from cyber attacks

Don't duck yet, but experts are predicting the next large-scale military or terrorist attack on the United States may be a cyber attack. Experts say last week's attack on the former Soviet republic of Georgia was preceded by an Internet assault that overwhelmed the Georgian government. And these security experts say a cyber attack could be just as devastating to the U.S. economy and infrastructure as a deadly bomb.

"Nobody's come up with a way to prevent this from happening, even here in the U.S.," said Tom Burling, acting chief executive of Tulip Systems, an Atlanta web-hosting firm that volunteered its Internet servers to protect the nation of Georgia's websites from malicious traffic.

"The U.S. is probably more Internet-dependent than any place in the world," Burling continued. "So to that extent, we're more vulnerable than any place in the world to this kind of attack. So much of what we're doing [in the United States] is out there on the Internet, and all of that can be taken down at once."
