Description: 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.What will you learn?Understanding Network Vulnerabilities: Explore the fundamental concepts of network security, dissecting common vulnerabilities and the tactics attackers employ to exploit them. Gain insights into the mindset of cybercriminals and the motivations behind their actions.Building a Secure Infrastructure: Learn how to design and configure secure network architectures using industry-leading practices. Dive into the world of firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS) to create effective defensive barriers.Securing Wireless Networks: Master the techniques to protect wireless networks from unauthorized access and eavesdropping. Discover how to implement robust encryption protocols, set up secure access points, and manage wire
