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.

Outlining the efficacy of existing forensic tools and the emergence of enhanced processes and tools


There has always been a need to validate forensic processes and tools as well as determining the trustworthiness of the digital evidence they recover and analyze. The processes and tools must present verifiable results as to how they produce evidence that is complete, authentic, and accurate, and has integrity and accuracy. While there has been a call from within the discipline emphasizing a scientific review of tools and processes, there have been complaints about the reliability of the tools. Questions have been raised as to their capability to gather data and the susceptibility of the imaged data to forgery.

Reports emerge from time to time of the apparent malfunction of some types of forensic hardware during data recovery, raising doubts as to the effectiveness of the imaging and hashing process. There have been earlier complaints from practitioners of forensic tools being incapable of...
