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.

Recovering digital evidence through forensic imaging processes


The practitioner takes possession of the physical exhibits that contain digital evidence, which are kept in secure storage in exactly the same way as other exhibits. As discussed in Chapter 3, The Nature and Special Properties of Digital Evidence, the courts recognize the increased risk of evidence tampering and authentication problems with digital evidence. Tampering of digital evidence is relatively easy and has, in the past, created great uncertainty about its soundness. The use of reliable forensic tools minimizes the risk of evidence contamination during formal recovery of digital data. Regrettably, the immature status of digital forensics as a scientific discipline continues to cause disagreement over defining helpful and broadly accepted standards and processes.

A practitioner has the option of undertaking a dead recovery or a live recovery of data from a computer believed to hold evidence of value. However, the practitioner...
