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.

The chapter explains the importance of preserving digital evidence in line with legal expectations. It describes the forensic processes and tools used to acquire digital evidence without undue contamination. The topics covered in this chapter are as follows:

  • The concept of the chain of custody in relation to the preservation of evidence from its collection up to its tendering in legal proceedings

  • The acquisition and safe custody of digital devices and data

  • The recovery of digital evidence through forensic imaging processes, also known as dead recovery

  • The acquisition of digital evidence through live recovery processes

  • The efficacy of existing forensic tools and the emergence of enhanced tools

  • Case studies that highlight the processes and pitfalls of recovering and preserving digital...
