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.

Remote access and malware threats


The prevalence of malware and other exploits through hacker attacks, often through remote-access exploits, remains a significant threat to computers and network systems that are vulnerable because of poor security management. These issues are discussed in the following subsections.

Remote access

The "Trojan defense" has been used by guilty as well as innocent computer users to support claims of their innocence by blaming the presence of illegal activities on their computers on remote attackers. While this is plausible, there seems to be a reversal of the onus of proving innocence, with the defendant instead of the prosecutor taking on the role. The big bugbear in all digital forensic examinations is linking the suspect to incriminating events. It would be fairer, but obviously too time-consuming on occasion, for the practitioner to clarify the possibility or likelihood of a remote-access exploit.
