Abstract : Few would argue with the premise that new and emerging information and communication technologies are transforming the ways that people around the world work, play, think, and live. Indeed, there is a sense that the transformations underway are so fundamental, so pervasive and all- encompassing, so qualitatively and quantitatively different, that they are ushering in a new era, the so-called Information Age. What does this mean for national security, and how will the concept of national security change because of Information Age technologies? Is the Information Age bringing with it new challenges and threats, and if so, what are they? What sorts of dangers will these challenges and threats present? From where will they-and do they-come? Is Information Warfare a reality? What responses will be required, and by whom, to safeguard national security from a potential adversary's information warriors during the Information Age? And how will national security decision-making be affected? This publication, Volume II of the Information Age Anthology, explores these questions and provides preliminary answers to some of them. This volume follows on the heels of Volume I of the Information Age Anthology, published in 1997 by NDU Press and DoD GGRP Publications, which examined the broader context of the impact of new and emerging information and communication technologies on business, commerce and services; government and the military; and international affairs. It is within this broader context of human activities that questions of national security must be pursued. This publication also precedes Volume III of the Information Age Anthology. Volume III will provide a detailed examination of the potential impacts of new and emerging information and communication technologies on military affairs and operations.
