Wireshark for Network Analysis and Troubleshooting

Every digital interaction leaves a trail of packets across the network, but making sense of this data requires the right skills and tools. Understanding network traffic is essential for troubleshooting connection issues, optimizing performance, and identifying potential security threats. This text-based course guides you from network analysis novice to a confident practitioner. You will learn to read packet captures, interpret network protocols, and isolate issues efficiently using written explanations, clear examples, and practical analytical exercises. What you'll learn: - Understand foundational networking concepts, packet structures, and the Wireshark interface - Capture live network traffic and work with standard PCAP files for offline analysis - Apply powerful display and capture filters to isolate specific conversations and protocols - Analyze modern web protocols including HTTP/2 and inspect encrypted traffic patterns with TLS 1.3 - Detect unusual network behavior, latency issues, and potential security anomalies - Practice diagnosing common network bottlenecks and configuration errors through guided scenarios The journey begins with essential networking terminology and interface navigation before moving into practical packet capture techniques. You will then progress to advanced filtering, protocol analysis, and real-world troubleshooting scenarios designed to build your diagnostic confidence. This course is designed for aspiring network administrators, IT support specialists, and cybersecurity beginners. No prior experience with packet analysis is required.
