Practical Digital Forensics

Chapter 1. The Role of Digital Forensics and Its Environment

The purpose of this book is to provide you with a clear understanding of digital forensics from its relatively recent emergence as a subdiscipline of forensics to its rapidly growing importance alongside the more established forensic disciplines. This chapter will enable you to gain a clear understanding of the role of digital forensic practitioners and the cybercrime and corporate environments, where they are actively seeking evidence of crimes and civil offences. A small sample of case studies of digital crime scenes will enable you to understand the complexity typical of many cases and the challenges posed to the forensic practitioner.

During the past 10 years or so, there has been a growing interest in digital forensics as a part of tertiary courses and as a career path in law enforcement and corporate investigations. New technologies and forensic processes have developed to meet the growing number of cases relying on digital evidence. However, it has been apparent that the increasing complexity, size, and number of cases is creating problems for practitioners, who also face resource and costing restrictions as well as a shortage of well-trained, experienced personnel. The book will describe these challenges and offer some solutions that have helped me in my practice and research endeavors, and which will hopefully assist and empower current and prospective practitioners to manage problems more effectively in the future.

Inherent security problems associated with personal computers, tied to their popularity in the workplace, have spawned new problems for law enforcement. For example, organizations undertaking criminal investigations or completing internal audits typically encounter the tedious examination of computer records to recover digital evidence. Such examinations urgently require new forensic processes and tools to help practitioners complete their examinations more effectively.

These are exciting times for those practitioners seeking to enhance their important role in assisting the legal fraternity. For those wishing to join the discipline, they will be doing so at a time when practitioners are at a crossroads in terms of changes affecting evidence recovery and management. Banality, complacency, and fatigue are common within the discipline, and the enthusiasm of entering the profession can rapidly dissipate because of the tedium and heavy caseloads, notwithstanding the inherently exciting and important nature of the work. What will be shared with you are new and more effective ways of reducing tedium and time wastage, reinvigorating practitioners, and restoring the excitement of the hunt for evidence, heralded by the gentle winds of change sweeping across the discipline that will eventually turn into a whirlwind if some challenges are left unattended.

The following topics will be covered in the chapter:

  • An outline of the history and purpose of forensics and, specifically, digital forensics
  • Definitions of the discipline and its role vis-à-vis more established forensic disciplines
  • Descriptions of criminal investigations and the rise and nature of cybercrime
  • An outline of civil investigations and the nature of e-discovery, disputes, and personnel disciplinary investigations
  • An insight into the role of digital forensic practitioners, the skills and experience required, and the challenges confronting them
  • A presentation of case studies of noteworthy digital forensic crime scenes to highlight the topic

Description

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.

Who is this book for?

This book is for anyone who wants to get into the field of digital forensics. Prior knowledge of programming languages (any) will be of great help, but not a compulsory prerequisite.

I can appreciate the realistic approach by the author to outline the challenges in the field. By the end of the book, the tone becomes a bit distracting with only some glimpses of optimism. There is good information contained in it, and my research on the other available texts is non-existent, so I'm not sure how it stacks up to others. The case studies and application on the material with each chapter were the real highlights.
