The US director of national intelligence puts cyber attacks at the top of the list of threats to the US. While countries like Iran are the most likely to launch crippling attacks, Clapper notes wisely that the technology is developing more quickly than the ability to assess the risks. This is plenty true in the case of China.

It’s all the more reason for the US to think strategically about its data and network security.
The fact that the DNI is testifying about hacking is a positive. This threat will not go away.

It is part of the changed strategic landscape in this new online cold war.
