Wireshark for Network Forensics An Essential Guide for IT

With the advent of emerging and complex technologies, traffic capture and analysis play an integral part in the overall IT operation. This book outlines the rich set of advanced features and capabilities of the Wireshark tool, considered by many to be the de-facto Swiss army knife for IT operational activities involving traffic analysis. This open-source tool is available as CLI or GUI. It is designed to capture using different modes, and to leverage the community developed and integrated features, such as filter-based analysis or traffic flow graph view.

You'll start by reviewing the basics of Wireshark, and then examine the details of capturing and analyzing secured application traffic such as SecureDNS, HTTPS, and IPSec. You'll then look closely at the control plane and data plane capture, and study the analysis of wireless technology traffic such as 802.11, which is the common access technology currently used, along with Bluetooth. You'll also learn ways to identify network attacks, malware, covert communications, perform security incident post mortems, and ways to prevent the same.

The book further explains the capture and analysis of secure multimedia traffic, which constitutes around 70% of all overall internet traffic. Wireshark for Network Forensics provides a unique look at cloud and cloud-native architecture-based traffic capture in Kubernetes, Docker-based, AWS, and GCP environments.
