Bankers play 'war game' to test systems

Britain’s banks and financial firms are taking part in a major cyber “war game” exercise today to test their defences against the mounting threat of online attack.

The simulation – dubbed Waking Shark II – is set to be one of the largest of its kind in the world, involving teams of staff from dozens of banks and other City institutions and overseen by officials from the Bank of England, the Treasury and Financial Conduct Authority.
