In this book, Tony Sammes and Brian Jenkinson show how information held in computer systems can be recovered and how it may be deliberately hidden or subverted for criminal purposes. "Forensic A Practitioner's Guide" is illustrated by plenty of case studies and worked examples, and will help practitioners and students gain a clear understanding * how to recover information from computer systems in such a way as to ensure that its integrity cannot be challenged and that it will be accepted as admissible evidence in court * the principles involved in password protection and data encryption * the evaluation procedures used in circumventing these safeguards * the particular legal issues associated with computer-generated evidence and how to ensure admissibility of such evidence.
