Overview of this book

Network forensics is a subset of digital forensics that deals with network attacks and their investigation. In the era of network attacks and malware threat, it’s now more important than ever to have skills 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. Towards 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 forensics analysis tasks.

Automated Evidence Aggregation and Analysis

Throughout this book, we've covered most of the manual techniques to uncover network evidence. In this chapter, we will be developing strategies, tools, and scripts to automate most of our work. Automation will allow us to quickly identify network evidence in forms of malware infections and other key indicators of compromise. Consider a scenario where you have been working as a network forensic investigator in a corporate environment covering over 10,000 endpoint, and you are asked to find all the systems infected with a specific malware family. Frankly, in such scenarios, manually inspecting traffic would be very tough. Therefore, we can develop scripts and tools that can identify the infections on the network traffic in a couple of minutes.

In this chapter, we will cover the following topics:

  • Automation using Python and Scapy...
