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.

Summary


This chapter described some problems of unsound digital evidence, the need for impartiality in undertaking forensic examinations, and some common pitfalls that diminish the value of digital forensics through cursory and biased examinations.

The pressing need for structured and balanced analysis was outlined, as was the need to validate evidence to determine its relevance and authenticity in anticipation of it being tendered in legal proceedings. The process stressed the importance of testing and checking the evidence to ensure it is what it purports to be. This included the discussion of a more structured analysis of the evidence collected, including the development and testing of hypotheses and counterarguments in line with forensic standards.

A prototype model of validation was presented, intended to benefit practitioners in handling complex evidence, in which the process of testing and checking digital evidence was presented through a sample scenario. The presentation of evidence...
