Keith AlexanderThe U.S. military is ill-prepared for waging cyber warfare and needs to bolster defenses against the growing threat of cyber attacks against both military systems and private infrastructure, the commander of U.S. Cyber Command told Congress on Thursday. “Those attacks are coming and I think those are near term and we’re not ready for them,” said Army Gen. Keith Alexander, head of Cyber Command and also outgoing director of the National Security Agency. Alexander, in prepared testimony to the Senate Armed Services Committee, sounded the alarm on the need for better cyber attack and defense capabilities.
