What is “CISPA”?

CISPA stands for The Cyber Intelligence Sharing and Protection Act, a network and Internet security bill written by Rep. Mike Rogers (R-MI) and Dutch Ruppersberger (D-MD) (H.R. 624). The bill purports to allow companies and the federal government to share information to prevent or defend against network and other Internet attacks. However, the bill grants broad new powers, allowing companies to identify and obtain “threat information” by looking at your private information. It is written so broadly that it allows companies to hand over large swaths of personal information to the government with no judicial oversight—effectively creating a “cybersecurity” loophole in all existing privacy laws.
