Network forensics is a subset of digital forensics that deals with network attacks and their investigation. In the era of network attacks and malware threats, it's now more important than ever to have the skills required to investigate network attacks and vulnerabilities.

Hands-On Network Forensics starts with the core concepts within network forensics, including coding, networking, forensics tools, and methodologies for forensic investigations. You'll then explore the tools used for network forensics, followed by understanding how to apply those tools to a PCAP file and write the accompanying report. In addition to this, you will understand how statistical flow analysis, network enumeration, tunneling and encryption, and malware detection can be used to investigate your network. Toward the end of this book, you will discover how network correlation works and how to bring all the information from different types of network devices together.

By the end of this book, you will have gained hands-on experience of performing forensic analysis tasks.

This book is aimed at incident responders, network engineers, analysts, forensic engineers, and network administrators who want to extend their knowledge beyond that of a beginner to a level where they understand the science behind network protocols and the critical indicators in an incident, and are able to conduct a forensic search over the wire.

, Introducing Network Forensics, lays the network forensics base for you and will focus on the key concepts that will aid in understanding network anomalies and behavior.

, Technical Concepts and Acquiring Evidence , focuses on developing some fundamental knowledge and insights into network forensics. This chapter will discuss the IP suite, the collection of evidence, and internetworking through hands-on practical exercises.
