The Pentagon has said that the Common Access Card for network login will be phased out for useage over the next two years, with biometric authentication taking its place.Pentagon CIO Terry Halvorsen confirmed the news on Tuesday, stating that the new authentication will be synchronised across the US military and its allies, reported FedScoop."We are embarking on a two-year plan to eliminate CAC cards from our information systems," Halvorsen told the 2016 Federal Forum, presented by Brocade and produced by FedScoop. He said the department would keep its public key infrastructure, or PKI, encryption architecture but that CAC cards "are not agile enough to do what we want."He said that biometrics will be used but with behavioural technologies also playing a role."We may still use them to get into a building, but we're not going to to use them for our information systems. We're going to use true multifactor [authentication]," he said.Iris scans and behavioral analytics "are all doable now," but CAC cards could be replaced by "some combination of behavioral, probably biometric and maybe some personal data information that's set from individual to individual."The need to integrate with other English-speaking "Five Eyes" nations – Australia, Britain, Canada and New Zealand – and NATO allies was another major reason behind the decision to abandon CAC cards.
