For courses in Criminal Justice, Computer Crime, Cyber Crime, and Computer Forensics. Written for first responders, this text was developed to address the need for an investigator's guide to high tech crime. Filled with real world examples, it is meant to be a hands-on training tool as well as a long-term reference manual. Chapters and materials are sequenced using a building block approach-one that ensures all students have the baseline knowledge needed to advance to the more complex topic areas. With an emphasis on demystifying the world of high tech crime, this book uses plain terms and real world analogies to make concepts accessible and meaningful to those on the front lines.
