The U.S. Navy Is Paying Much More Attention to Cyber Threats

Navy Secretary Ray Mabus said Wednesday that the U.S. Navy is working hard to improve the cyber security of its computer networks and weapon and communications systems, while bracing for potential attacks on power grids and fuel supplies. Mabus said cyber warfare was a clear threat given Russia's use of cyber attacks before its physical invasions of Crimea and Georgia. Mabus also confirmed a recent Wall Street Journal report that the Navy was looking at replacing IBM servers used for its Aegis combat system after International Business Machines Corp's $2.1 billion sale of its server division to China's Lenovo Group Ltd last year. The secretary concluded by saying that the Navy was including more cyber threats in its war games and moving to develop alternative energy sources and microgrids.
