How can any organisation detect the onset of an attack on its computer network, giving it time to respond quickly and block any intrusion or compromise of its data? The answer could lie in game theory.
Modern firewalls and other technology are already in place, but these have not prevented major attacks on prominent networks in recent months. Now, information technologist Heechang Shin of Iona College in New Rochelle, New York, has used game theory to develop a defence mechanism for networks that is more effective than previous approaches.
Shin explains that each incident might not only severely disrupt services affecting thousands of people, but for a commercial operation it can take as much as one percent of annual sales, per incident, amounting to tens of millions of dollars, according to an Iona statement.
