Overview of this book

A computer forensics investigator must possess a variety of skills, including the ability to answer legal questions, gather and document evidence, and prepare for an investigation. This book will help you get up and running with using digital forensic tools and techniques to investigate cybercrimes successfully. Starting with an overview of forensics and all the open source and commercial tools needed to get the job done, you'll learn core forensic practices for searching databases and analyzing data over networks, personal devices, and web applications. You'll then learn how to acquire valuable information from different places, such as filesystems, e-mails, browser histories, and search queries, and capture data remotely. As you advance, this book will guide you through implementing forensic techniques on multiple platforms, such as Windows, Linux, and macOS, to demonstrate how to recover valuable information as evidence. Finally, you'll get to grips with presenting your findings efficiently in judicial or administrative proceedings. By the end of this book, you'll have developed a clear understanding of how to acquire, analyze, and present digital evidence like a proficient computer forensics investigator.

Summary

In this chapter, we have gone over standard email protocols; the system uses SMTP for sending emails, while POP and IMAP are used for receiving emails. IMAP also includes features that can be used to manage the user's inbox. We went over the email header and the components that make up the header. WebMail and email clients were also discussed.

You now have the skills necessary to read an email header and determine the servers that were used to transmit the email, as well as what protocols the system used to send and receive the email. When conducting a digital forensic examination, you can now identify artifacts from typical email clients and web-based email.

In the next chapter, you will learn that some web-based emails have similarities among them.
