This course is a comprehensive guide to understanding and securing computer networks. You will learn how the internet works, how packets are structured, how hackers exploit weak links, and how to defend against attacks — all through hands-on analysis using Wireshark, TcpDump, and real-world packet captures.

You will start with the fundamentals — including network layers, protocols, and traffic behavior — and progress to intrusion detection, threat modeling, and vulnerability assessment. We dive into packet sniffing, filtering, TCP/IP structure, and ARP/IP routing logic, then show how these relate to cybersecurity defense.

We’ll set up a complete cybersecurity lab using Kali Linux, Metasploitable, and virtual machines, enabling real practice in a safe environment. Whether you're analyzing TCP packets, detecting DNS spoofing, or understanding port scans, this course gives you the practical skills to identify and defend against modern threats.
