Hands-On Network Forensics

Investigate network attacks and find evidence using common network forensic tools
In the era of network attacks and malware threat, it becomes important to have skills to investigate the attack evidence and vulnerabilities prevailing in the network. This book focuses on how to acquire and analyze the evidence, write a report and use the common tools in network forensics.

Gain basic skills in network forensics and learn how to apply them effectively

• Investigate network threats with ease
• Practice forensics tasks such as intrusion detection, network analysis, and scanning
• Learn forensics investigation at the network level

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.

• Discover and interpret encrypted traffic
• Learn about various protocols
• Understand the malware language over wire
• Gain insights into the most widely used malware
• Correlate data collected from attacks
• Develop tools and custom scripts for network forensics automation

The book targets incident responders, network engineers, analysts, forensic engineers and network administrators who want to extend their knowledge from the surface to the deep levels of understanding the science behind network protocols, critical indicators in an incident and conducting a forensic search over the wire.
