From the Financial Times: The US and its Nato allies have been urged to collaborate more intensely to fend off the threat of cyber-attacks in the aftermath of the alleged Chinese assault on Google.

The Pentagon’s top cyber-strategist said shared warning systems had to be established and government contacts broadened.

In an interview with the Financial Times, William J. Lynn, US deputy defence secretary, said America and the UK had been working to counter the growing international danger of cyber-attacks…

“You can’t just protect the system by defending yourself from inside your own country,” Mr Lynn said on a visit to London. “International co-operation is imperative for establishing the chain of events in an intrusion and quickly and decisively fighting back.” (photo: U.S. Department of Defense)
