A simulated attack has been carried out across European web services to test the continents’ online defences.
The exercise, carried out by the European Network Security Agency and the Joint Research Center, aimed to find out how well countries could work together to cope with a widespread attack aimed at slowing network connections between different nations and to reveal any weaknesses in the procedure for dealing with a cyber assault.
The simulation also tested how nations would communicate in the event of a full network shutdown of international links.
Neelie Kroes of the European Commission for the Digital Agenda, claimed: "This exercise to test Europe's preparedness against cyber threats is an important first step towards working together to combat potential online threats to essential infrastructure and ensuring citizens and businesses feel safe and secure online."
A report examining how each nation coped with the attacks will be released on the 10th of November.
