State Department upgrades network security against cyber attacks
The State Department on Friday said it was upgrading the security of its unclassified computer network to defend against cyber attacks, leaving some employees unable to send outside emails or access the internet.
Department spokeswoman Jen Psaki said the agency, which in November said it had suffered a cyber attack, was improving "the security of its main unclassified network during a short, planned outage of some Internet-linked systems."
