The Protecting Cyberspace as a National Asset Act of 2010 (S. 3480) is a bill introduced in the United States Senate by Joe Lieberman (Independent Democrat, Connecticut), Susan Collins (Republican Party, Maine), and Tom Carper (Democratic Party, Delaware) on June 10, 2010. The stated purpose of the bill is to increase security in cyberspace and prevent attacks which could disable infrastructure such as telecommunications or disrupt the nation's economy. The legislation would create an Office of Cyberspace Policy and a National Center for Cybersecurity and Communications.
Senator Lieberman has been criticized for giving the President the power to use a "kill switch" which would shut off the Internet. He has called these accusations "total misinformation" and said that "the government should never take over the Internet". Lieberman further inflamed skeptics when he cited China's similar policy in a backfired attempt to show the policy's normalcy. However, the bill would allow the President to enact "emergency measures" in the case of a large scale cyber attack. The original bill granted the US President the authority to shut down part of the internet indefinitely, but in a later amendment the maximum time for which the President could control the network was reduced to 120 days. After this period, the networks will have to be brought up, unless Congress approves an extension.
