Unlike traditional security devices, which are static, these "digital ants" wander through computer networks looking for threats, such as "computer worms" - self-replicating programs designed to steal information or facilitate unauthorized use of machines. When a digital ant detects a threat, it doesn't take long for an army of ants to converge at that location, drawing the attention of human operators who step in to investigate. The concept, called "swarm intelligence," promises to transform cyber security because it adapts readily to changing threats. "In nature, we know that ants defend against threats very successfully," explains Professor of Computer Science Errin Fulp, an expert in security and computer networks. "They can ramp up their defense rapidly, and then resume routine behavior quickly after an intruder has been stopped. We were trying to achieve that same framework in a computer system." Current security devices are designed to defend against all known threats at all times, but the bad guys who write malware - software created for malicious purposes - keep introducing slight variations to evade computer defenses.
