Network Protocol Analysis with Wireshark for Beginners

Every day, millions of data packets travel across your network, carrying critical information and potential security threats. This course teaches you how to capture and analyze this traffic, giving you the visibility needed to keep your systems running smoothly and securely. You will start by learning foundational networking concepts before moving into hands-on packet inspection. Through detailed written explanations and structured analysis exercises, you will learn how to isolate network issues, analyze protocol behavior, and recognize suspicious activity. What you'll learn: - Understand the fundamentals of packet capturing and the OSI model. - Navigate the Wireshark interface and customize your analysis workspace. - Apply powerful display filters to isolate specific network conversations. - Analyze core protocols including TCP, UDP, DNS, and modern IPv6 traffic. - Inspect secure web traffic by understanding TLS 1.3 handshake structures. - Troubleshoot network performance issues like packet loss and latency. This course begins with key terminology and foundational definitions, ensuring you have a strong grasp of network basics before analyzing live traffic. You will then progress through written walkthroughs of real-world packet captures to build practical troubleshooting skills. This course is designed for beginners in IT, systems administration, or cybersecurity who want to learn network analysis from the ground up. No prior packet analysis experience is required.
