Overview of this book

We live in a highly networked world. Every digital device—phone, tablet, or computer is connected to each other, in one way or another. In this new age of connected networks, there is network crime. Network forensics is the brave new frontier of digital investigation and information security professionals to extend their abilities to catch miscreants on the network. The book starts with an introduction to the world of network forensics and investigations. You will begin by getting an understanding of how to gather both physical and virtual evidence, intercepting and analyzing network data, wireless data packets, investigating intrusions, and so on. You will further explore the technology, tools, and investigating methods using malware forensics, network tunneling, and behaviors. By the end of the book, you will gain a complete understanding of how to successfully close a case.

About the Reviewers


In this chapter, we moved our skills up a notch. We learned how to analyze the captured packets to see what is happening on the network. We also studied how to see the traffic from the specific IP addresses as well as protocol-specific traffic. We also understood how to look for specific traffic based on keywords. Files, private credentials, and images have been examined to identify activities of interest. We have now become a lot better at investigating network activity.

In the next chapter, we are going to expand our skills and further our understanding of wireless networks, their security, as well as the common attacks that are out there. We will also look at how to sniff traffic and analyze it from our perspective.
