Top brass in the Pentagon think that the US government should create a "secure zone" on the world wide wibble just for federal agencies and critical private sector industries to protect them from potential attacks.
General Keith Alexander, who heads the US Cyber Command, said that a special network which was sectioned off from the rest of the Internet was inevitable for systems crucial to national security.
Basically this would be a secure private internet where government and critical infrastructure would operate.
Alexander said that at some point the idea is going to be on the table and the question is how would the army do it.
Although setting up the network was a doddle it would be difficult to sell to the businesses involved. It might also be hard to sell to the great unwashed.
Testifying in front of the House Armed Services Committee Alexander said the Pentagon would likely have to work with the Department of Homeland Security and the Federal Bureau of Investigations to secure the country's critical infrastructure.
But part of the problem was that 85 percent of these networks were owned by private companies.
Alexander added that defence agencies may need additional powers to take action during a cyber attack.
There are several pieces of competing cybersecurity legislation pending in Congress that would give them that power, but lawmakers have been unable to settle on which agency should regulate civilian cybersecurity.
DHS is currently in charge and Alexander said the Pentagon has no role. To be honest he didn't think that it was a good idea to operate domestically unless asked for help.
