This module dives deep into the art and science of packet analysis using Wireshark, the industry-standard network protocol analyzer. You will learn how to capture live network traffic, apply advanced display filters, and decode complex protocol interactions across the OSI model. From a cybersecurity perspective, packet analysis is the ultimate source of truth for network forensics, performance troubleshooting, and threat hunting. You will discover how defenders use Wireshark to detect covert channels, analyze malware beacons, and reconstruct compromised sessions, while understanding how attackers attempt to evade detection through fragmentation and obfuscation.
