Privacy group sues to get records about NSA-Google relationship

The National Security Agency should divulge information about its reported agreement with Google to help the Internet company defend itself against foreign cyber attacks, according to a lawsuit filed Sept 13 by a privacy group. The ad hoc and secretive nature of Google's arrangement with the federal spy agency also spotlights what some experts said was the lack of a clear federal plan to deal with the growing vulnerability of U.S. computer infrastructure to cyber intrusions launched from foreign countries. At risk are power grids, banks and other crucial public services.
