Security consultant James Arlen says the hysteria over Stuxnet has had the effect of creating a secondary wave of panic about the vulnerability of industrial control and SCADA systems. The idea that a remote attacker, no matter how sophisticated or well-funded, could cause mass chaos in a water plant or food-production facility by compromising one or two control systems just doesn t wash, he says. Arlen encouraged security professionals to take a deep breath and assess the situation rationally. Stuxnet is the first time we ve seen an intelligent piece of malware that s an awesome engineered artifact, Arlen said.
