Landau describes what makes communications security hard, warrantless wiretapping and the role of electronic surveillance in the war on terror, the economic threats posed by electronic spying, and the risks created by embedding wiretapping into communications networks. How can we get communications security right? Landau offers a set of principles to govern wiretap policy that will allow us to protect our national security as well as our freedom.
