Learning Network Forensics

By: Samir Datt

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.

This allowed the attackers to maintain a persistent presence in the router, thereby exposing the network traffic and enabling the router to act as a listening post for the attacker.

Routers have long been the cornerstone of the Internet. The role of the router has been to connect the networks to the Internet and choose the best path so that the information arrives quickly. In fact, the global trend is that the national network infrastructures are dependent on the routers to handle the network traffic. Therefore, it stands to reason that if routers carry the world's traffic, they would also be privy to all the associated traffic logs:

Seeing the kind of role that routers play, routers are often the target of attacks, especially Denial-of-service (DoS) or disabling the router type of attacks. Router compromise is...
