The European Commission has announced plans to shield itself against cyber-attacks, as threats in this sector continue to grow. The defence system will be based on the prevention and detection of cyber-attacks, thanks to a pan-European ‘cyber-shield’ made up of public and private centres. This will mean entrusting part of the bloc's defence to private companies and forcing member states to cooperate, which Margrethe Vestager, executive vice-president of the EC, says is necessary. ‘No one can solve this alone. You cannot have sufficient resources ready because you don't know when you will have an all-out cyberattack,’ Vestager said. ‘We have seen cyberattacks on the Irish health system. We have seen attacks giving access to foreign ministries go undiscovered for months. The proposals, costing €1.1 billion, will have to be reviewed by member states and the European parliament before being implemented.
