Practical Windows Forensics

Overview of this book

Over the last few years, the wave of the cybercrime has risen rapidly. We have witnessed many major attacks on the governmental, military, financial, and media sectors. Tracking all these attacks and crimes requires a deep understanding of operating system operations, how to extract evident data from digital evidence, and the best usage of the digital forensic tools and techniques. Regardless of your level of experience in the field of information security in general, this book will fully introduce you to digital forensics. It will provide you with the knowledge needed to assemble different types of evidence effectively, and walk you through the various stages of the analysis process. We start by discussing the principles of the digital forensics process and move on to show you the approaches that are used to conduct analysis. We will then study various tools to perform live analysis, and go through different techniques to analyze volatile and non-volatile data.

Preface

Disk wiping in Linux


The investigator can't use the same hard drive for two different hard drives if they are using the duplication way to image the hard drive. This could overlap different files from different cases and will result in unreliable and untrue findings. After completing work on the duplicate hard drive, you must wipe it and prepare it for another case or hard drive. Don't wait until another case is assigned to you; wiping takes a long time.

This process is equivalent to the imaging process but the source file is a file full of zeros. In the Linux operating system there is a /dev/zero file. You need to use this file as your input file to the dd tool, and your output file will be the hard drive that needs to be wiped. Another file that can be used in this process as well is/dev/null:

dd if=/dev/zero of=/dev/sda bs=2K conv=noerror,sync
