To meet the threat of a cyber attack, Jack Goldsmith imagines that sometime in the near future the government mandates the use of a government-coordinated intrusion-prevention system throughout the domestic network to monitor all communications, including private ones. Although such a program would be controversial, Goldsmith argues that massive government snooping in the network can be lawful and deemed consistent with the U.S. Constitution, including the Fourth Amendment, if proper and credible safeguards are put in place.--Publishers' website.
