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 technical complexities of digital evidence


This section outlines the technical complexities of digital evidence and challenges to sound analysis. Like any form of indirect evidence, there are challenges to understanding more complex evidence artifacts recovered from a crime scene. Because of the technical complexity of digital evidence and its environment, some experience and specialized knowledge is required. Now that we have looked at examples of just how useful file and metadata information can be to the practitioner, understanding clearly and more fully the nature of digital information is vital. This section will introduce some challenges in using and analyzing digital evidence that show that digital forensics, which often provides such important material, is not a walk in the park.

Well before the emergence of electronic and digital data, it was difficult to forge and alter physical documents compared with digital data because of security measures protecting valuable documents and...
