Description
Wireshark is a powerful network protocol analyzer tool that allows you to monitor the data traveling on your network. It provides detailed insights into network traffic, enabling you to spot issues and analyze packets in-depth. With Wireshark, you can filter and search for specific network communications, view these details at various levels from basic overview to packet-by-packet inspection, and even create custom profiles for specific tasks. Advanced users can decrypt SSL/TLS traffic, analyze VoIP calls, and automate tasks using command line options. Expert users can write custom dissectors and perform advanced statistical analysis. Understanding Wireshark is crucial for network troubleshooting and security analysis.
