A recently proposed but little-noticed Senate bill would allow the federal government to shut down the Internet in times of declared emergency, and enables unprecedented federal oversight of private network administration.

The bill's draft states that "the president may order a cybersecurity emergency and order the limitation or shutdown of Internet traffic" and would give the government ongoing access to "all relevant data concerning (critical infrastructure) networks without regard to any provision of law, regulation, rule, or policy restricting such access."

Authored by Democratic Sen. Jay Rockefeller of West Virginia and Republican Olympia Snowe of Maine, the Cybersecurity Act of 2009 seeks to create a Cybersecurity Czar to centralize power now held by the Pentagon, National Security Agency, Department of Commerce and the Department of Homeland Security.
