Re: Not under THIS...
This is not China; we have no great firewall. It is doubtful that the Constitution grants it the authority to enact laws that compel businesses or individuals to administer their systems in a secure way; and if they do, there is no way they have the resources to enforce such laws. As noted, they do not have the effective power to make their Secretary of State or OPM director to do that.
It would be interesting to see a presentation of the theory under which the federal government is responsible to "even begin to protect the digital assets of the US" other than those of federal agencies. The administration has argued that it should, but his was met with considerable pushback from many who were concerned about giving the government too much power - many of them now, doubtless, seriously agitated about the NSA and its activities.
They can, and do, sponsor various activities and organizations such as MITRE and CERT, but in many respects the internet and its connected systems are not fundamentally more secure than they were in November, 1988 - much depends on the diligence of the system and network administrators; some are competent and motivated to secure their systems, but all too many are lazy, incompetent, and do not care much beyond doing the minimum to ensure continuation of their regular paychecks.
