Wireshark Training

Wireshark training focuses on teaching the practical application of the Wireshark network protocol analyzer, a crucial tool for network analysis and troubleshooting. Learners are taught how to capture and inspect live network traffic, utilize powerful capture and display filters to isolate data of interest, and interpret the structure of common protocols such as TCP/IP, HTTP, and DNS. The core objective is to develop the ability to diagnose connectivity issues, analyze application performance, and examine potential security threats by dissecting the raw data packets that traverse a computer network.
