The US Department of Defence may announce its own Cyber Command.
As I understand from a US source close to that world, the DoD is considering appointing General Keith B. Alexander, director of the NSA, as the commander of the new unit.
Bear in mind that nothing is finalised yet, and may not be. What I've heard is that when the Air Force Cyber Command was proposed over a year ago, the DoD asked the Air Force not to go ahead with the plans, as Cyber Command was a DoD level problem and should not be controlled by individual services.
The Air Force subsequently set up a 24th Air Force to deal with cyber attacks instead.
My source thinks that the director of the NSA would be a good bet for commander as he already commands the Joint Functional Component Command for Network Warfare.
As I say, at the moment this is all just whispers.
