http://www.euronews.com/ For the first time, banks and internet companies were part of an exercise preparing EU institutions in case of a cyber attack.
Four hundred experts from across Europe faced more than 1,200 separate cyber attacks on Thursday.
The simulated threat came from a European security agency in Athens, but for those taking part, it meant coming up with coordinated reactions and defences to tackle the real danger of online attacks that can disrupt services, steal data and manipulate prices.
