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.

Solutions to the challenges posed by new hardware and software


Chapter 2, Hardware and Software Environments, described different operating systems and filesystems and introduced processes for locating evidence of potential value. Filesystems have become ponderously complex, perhaps unnecessarily so, but in doing so, they do retain information about past transgressions that may have otherwise been erased. The challenge is knowing where to look—assuming the practitioner knows how to navigate new operating systems and applications.

The traditional processes of imaging-indexing-searching or imaging and manually searching are becoming untenable; the sheer size and complexity is time-consuming and not necessarily guaranteed to locate the evidence, except by chance in many instances. There will always be a place for "deep rinse" analysis, but there are more effective ways. My research and fieldwork has shown that while it is difficult to part with familiar processes such as these, there exists...
