Description

Embarking on your journey with Wireshark can indeed feel overwhelming. I vividly recall my initial encounter with a trace file, where questions like "What should I look for?", "Where do I start?", and "What is 'normal'?" flooded my mind. The sheer volume of packet details left me momentarily paralyzed.If you've ever experienced similar feelings when analyzing a pcap file, this course is tailored for you.In this course, we'll delve into real-world scenarios to demonstrate practical applications of Wireshark in solving network issues. This skill set is invaluable for IT professionals aiming to enhance their analytical and troubleshooting capabilities. Our hands-on labs are designed for active participation: you'll download trace files, tackle accompanying questions, and piece together network puzzles embedded within the packets.As we navigate the intricacies of packet analysis, we'll also familiarize ourselves with the Wireshark interface. You'll learn to configure custom columns, apply filters, and set up coloring rules, all aimed at customizing the layout to swiftly identify problems. By the end of this course, you'll be comfortable with the Wireshark interface and possess the expertise to comprehend core protocols.My name is Typhon, and I bring years of experience in network analysis and troubleshooting. Throughout this course, I integrate real-world examples into every lecture, exercise, and assignment. My goal is to help you become adept with the Wireshark interface, interpret packet data effectively, and extract actionable insights to resolve issues or detect security incidents promptly.Ready to embark on this journey? Let's dive into the packets together!
