Since the turn of the century, much has happened in the world of politics, governments, spying, technology, global businesses, mobile communications, and global competition on nation and corporate levels. This book underscores how hostile countries, business competitors, terrorists, and others are waging Information Warfare (IW) against their adversaries from across the globe. It describes attacks on information systems through theft, Internet espionage, deception, and sabotage, and demonstrates countermeasures being mounted to defeat these threats.
