NATO to hold major cyber defense drill in Estonia
None
About 400 computer experts will participate in a major cybersecurity drill in Estonia this week as part of NATO's efforts to upgrade its capability to counter potentially debilitating hacker attacks, organizers said Tuesday.
Teams from 16 nations will take part in the Locked Shields 2015 exercise at NATO's cyberdefense center in Tallinn. The annual drill is one of the largest of its kind.
Officials said a key theme this year is the potential threat caused by the migration from the Windows 8 operating system to the upcoming Windows 10 system.
