Synopsis Over the past few decades, the rapid rise in information and communication technologies and their increasing prevalence in our society has revolutionised the communications process and with it the significance and implications of information warfare. Information warfare is the application of destructive force on a large scale against information assets and systems, against the computers and networks that support the four critical infrastructures. This book discusses the nature of information warfare and its impact in the new millennium. It also deals with practical methods and techniques that have proven to be effective in law enforcement. This work will be a highly informative reference tool for academics, students, researchers and all who concerned.
