Low-cost Strategy Developed For Curbing Computer Worms

A new, cost-effective strategy to limit the spread of worms through computer networks has been developed. The two-pronged plan compiles suspicious incoming activity from the network's computers to create an early-warning system for worm attacks. As the threat level rises and falls, an algorithm determines whether to toggle computers online or offline depending on whether the benefit of staying online outweighs the cost of worm infection, and vice versa.
