Master the fundamentals of network traffic analysis and web communication using Wireshark in this beginner-friendly guided project. Through hands-on activities, you’ll explore Wireshark’s interface, capture and filter network traffic, and analyze critical network protocols like HTTP and DNS. You’ll examine real-world packet captures to interpret HTTP requests and responses, measure DNS response times, and identify performance bottlenecks or security risks. By isolating specific traffic flows with filtering techniques, you’ll gain insights into network behavior and potential anomalies. This pr
