How much government control in cyber crisis

I read this article on MSNBC.com "How much government control in cybercrisis". There have been 18 bills already already introduced in Congress to define when and how the federal government should step in in case of digital disaster. The very number of bills is an indication that this subject is not understood or represented correctly by the lawmakers. It raises so many questions. What is the risk of an all out cyber attack? Should the federal government be given the authority to shut down the internet? Is this the right approach? Experts say that a system under attack should not be shut down, but isolate it and filter out the bad traffic from the good. Does the government have the agility to do something like that? I don't see it so much as a political issue as a technical one. The problem is that there is no one set way of implementing cyber security due to the vastness of the systems in place. Will there ever be a cut and dried way of securing information, or will it remain a moving target for the forseeable future?
