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.

In this chapter, we understood the concept of virtual private networks and their role in networks. We looked at the various types of VPNs and their tunneling protocols. We also studied how, just like smugglers, VPNs are used to ship foreign protocols via tunnels into a corporate network. At the end of the chapter, we looked at the ways in which the VPNs can be compromised and consequently, further lead to the compromise of our networks.

In the next chapter, we gear up to look at how to investigate malware, which is one of the major causes of network incidents. Malware has been on an evolutionary spiral and has emerged as a potent cyber weapon used to compromise digital resources across the globe.
