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.

Describing the physical acquisition and safekeeping of digital evidence


The process of handling digital evidence is especially vulnerable to errors. Just like blood samples or fingerprints, which may easily be contaminated at the crime scene, digital evidence may also be damaged during collection and extraction unless strict procedures are followed. The storage and safekeeping of physical records, such as witness statements, crime scene photographs, facsimiles of manuscripts, and so forth, require prudent record-keeping and safe custody, thus facilitating their production as evidence. It must be reiterated that the courts expect that digital evidence can be shown to be unaltered or contaminated from its point of seizure to the time it is tendered in legal proceedings.
