Practical Digital Forensics

By: Richard Boddington

Overview of this book

Digital Forensics is a methodology which includes using various tools, techniques, and programming language. This book will get you started with digital forensics and then follow on to preparing investigation plan and preparing toolkit for investigation. In this book you will explore new and promising forensic processes and tools based on ‘disruptive technology’ that offer experienced and budding practitioners the means to regain control of their caseloads. During the course of the book, you will get to know about the technical side of digital forensics and various tools that are needed to perform digital forensics. This book will begin with giving a quick insight into the nature of digital evidence, where it is located and how it can be recovered and forensically examined to assist investigators. This book will take you through a series of chapters that look at the nature and circumstances of digital forensic examinations and explains the processes of evidence recovery and preservation from a range of digital devices, including mobile phones, and other media. This book has a range of case studies and simulations will allow you to apply the knowledge of the theory gained to real-life situations. By the end of this book you will have gained a sound insight into digital forensics and its key components.

The structured and balanced analysis of digital evidence


Clearly, it is hoped that you, having read through previous chapters, would realize that intuition is not enough and does not impress the court—solid facts are needed and should be supported with logical analysis. Attempts must be made to locate all evidence and intuition alone may not be sufficient for an inexperienced practitioner to locate hidden and hard-to-find evidence. The incomplete identification of all evidence that should be located can thwart an examination of crucial facts. This may be due to the incompetence or inexperience of a practitioner or because of the lack of time and available resources.
