Internet infrastructure

President-elect Barack Obama recently announced an ambitious plan to build up the nation's Internet infrastructure as part of his proposed economic stimulus package.

Upgrading the Internet is a particularly smart kind of stimulus, one that would spread knowledge, promote entrepreneurship and make this country more competitive globally.

The United States has long been the world leader in technology, but when it comes to the Internet, it is fast falling behind. America ranks 15th in the world in access to high-speed Internet connections.

In the Citizen Lab at the University of Toronto, a new breed of hackers is conducting digital espionage.

They are among a growing number of investigators monitoring how traffic is routed through various countries, where Web sites are blocked and why it's happening. Now they are turning their scrutiny to a new weapon of warfare: cyber attacks.

Tracking wars isn't what many of the researchers set out to do. Many began intending to help people in countries that censor online content. But as the Internet has evolved, so has their mission.

Weeks before bombs started falling on Georgia, a security researcher in suburban Massachusetts was watching an attack against the country in cyberspace.

Jose Nazario of Arbor Networks in Lexington noticed a stream of data directed at Georgian government sites with the message: "win+love+in+Rusia."

A major flaw in the Internet infrastructure was leaked to the public Monday before many IT directors had the chance to apply security patches. The flaw was discovered weeks ago by Dan Kaminsky, a security expert at IOActive, who has worked with industry leading software developers investigating Internet vulnerabilities.
