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.

Chapter 3. The Nature and Special Properties of Digital Evidence

By the beginning of the twenty-first century, more than half of criminal cases involved a computing device of some description, and the trend has continued and is likely to rise. Its use in legal cases too has grown and shows no sign of diminishing. Digital evidence is derived from the examination of a wide range of digital devices and shares similar characteristics with other forms of evidence. There are some differences that enhance evidence recovery analysis, but, as will be seen in this book, there are characteristics that also make it challenging for practitioners.

This chapter defines and describes the special properties of digital evidence and its contribution to investigations. The topics specifically covered in this chapter will:

  • Define digital evidence and its use

  • Explain the special properties of digital evidence, including its time and location metadata and file characteristics

  • Highlight the technical complexities of...
