In This Review

Information warfare remains a nebulous subject, but this monograph offers one of the most interesting and revealing ways of thinking about it, at least in an unclassified venue. A short but comprehensive discussion of the central issues in information warfare, particularly defense against attacks on the myriad information systems that keep American society running, is followed by an ingenious "day after" exercise that illustrates and amplifies these problems. In three parts -- "the day of" an information attack, "the day after," and finally "the day before" -- participants can work their way through the decision-making problems of information warfare. The exercise, which has been tested with many government and private groups, is a brilliant device for exploring a problem bound to become more salient.
