What is Wireshark?
Wireshark is a free and open-source network protocol analyzer that allows for deep inspection of network traffic. It is used by network administrators, security professionals, and developers to understand, troubleshoot, and analyze data flowing across their networks. The tool helps in diagnosing network issues and examining communication protocols. Users capture network packets in real-time and then interactively browse the captured data. They can filter traffic, inspect individual packet details, and identify communication patterns. This helps in debugging network applications, identifying performance bottlenecks, and analyzing security vulnerabilities by examining the raw data exchanged between devices.
