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.

Explaining password security, encryption, and hidden files


The following sections describe password security and encryption and ways to protect information and conceal evidence from prying eyes. They outline the basic processes of managing the security of computer devices and networks as well as describing the reasons why digital information needs protection from a wide range of threats.

User access to computer devices

To protect data stored on a device from unauthorized access, user access controls offer some degree of protection. This applies to desktops, laptops, mobile phones and other handheld devices, home security systems, and a broad range of other electronic equipment. Not only is it essential to restrict direct human access to information to those who are authorized, but the information also needs protection from access by other programs, processes, or systems that may be connected to the device. For example, workers logged in to a network server should normally have no access to...
