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, you learned about another valuable resource in our endeavor to understand network forensics. The importance of logging and different parameters in log management have been highlighted and discussed. We understood the questions we need to answer when we are setting up a logging system that will assist us at the time of a network forensic investigation. We have seen the importance of clock accuracy, correlation, collection, storage, and a host of other factors in logging. We have seen how getting multiple and disparate logs into a single log management system can help us connect the dots and give us an insight into the activities of the intruders zeroing in on our network.

In the next chapter, we will move on to another very important area from an investigation perspective. We will look at proxies, firewalls, and routers with a network forensic investigator's eye. We will see the different types of the preceding devices that form a part of our security perimeter. We...
