The spectre of crashing power grids, stalled air control towers, hospitals brought to a standstill and defences left wide open was raised at the first cyber-security world summit that ended today, when politicians, officials, military leaders and industrialists warned that the US and other countries were failing to protect computer networks and were vulnerable to attacks of catastrophic proportions.Harry Raduege, former director at the Pentagon agency responsible for the computer network, said cyber attacks were growing in intensity and sophistication. “We have experienced a number of attacks against the financial sector, on the power grid and against our defence capability,” he told the meeting in Dallas.
