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.

Packet sniffing and analysis using NetworkMiner

NetworkMiner is a passive network sniffing or network forensic tool. It is called a passive tool as it does not send out requests—it sits silently on the network, capturing every packet in the promiscuous mode.

NetworkMiner is host-centric. This means that it will classify data based on hosts rather than packets, which is what most sniffers such as Wireshark do.

The different steps to NetworkMiner usage are as follows:

  1. Download and install the NetworkMiner.

  2. Then, configure it.

  3. Capture the data in NetworkMiner.

  4. Finally, analyze the data.

NetworkMiner is available for download at SourceForge:

Though NetworkMiner is not as well known as it should be, it's host-centric approach is refreshingly different and effective. Allowing the users to classify traffic based on the IP addresses and not packets helps us to zero in on activities related to the specific computers that are under suspicion or are being investigated...
