Fast-spreading computer viruses and worms continue to plague information networks – and the problem is getting worse. In an article published in the 23 April issue of the journal Science, HP Labs researcher Matt Williamson and others look at strategies that could reduce the damage caused by these cyber attacks.

Williamson and his co-authors examine the structure of different types of computer network that are vulnerable to attack and analyze their characteristics. Their research suggests that the most effective strategy to combat worm and virus attacks is a technique called Throttling, which limits the spread of a virus or worm by radically slowing the speed at which they can make new network connections.

In their article, Technical Networks and the Spread of Computer Viruses, the authors argue that a throttling mechanism would slow the spread of computer infections while leaving normal network traffic unaffected.
