More info: Pacific Northwest National Laboratory developed DigitalAnts™, a cyber-defense tool that was inspired by ant colonies. Real ants use “swarm intelligence” to identify areas of interest, laying down pheromone paths to attract other ants to the same areas. In DigitalAnts, sensor “ants” constantly look for system operations that could indicate an attack, quickly alerting each computer’s sentinel. Scientific American named digital ants in its Ten World Changing Ideas of 2010.
