Описание: Welcome to Day 20 of our cybersecurity and networking series! 🚀
In this lesson, we dive deep into Wireshark, one of the most powerful tools for network analysis.

🔍 What you’ll learn today:

What Wireshark is and why it’s called the “microscope of networks.”

How packet capture works (promiscuous mode explained).

Understanding the Wireshark interface: Packet List, Packet Details, and Packet Bytes.

Using filters to analyze only the traffic you care about.
