 - WireShark is an open-source and free software tool used to analyze network traffic and record data packets in computer networks. It was originally developed by Gerald Compton in 1998 and has gained popularity in recent years due to its ability to analyze network traffic in a detailed and comprehensive manner.

- WireShark is used for several purposes such as analyzing data packets, verifying network safety, troubleshooting and fixing errors, identifying performance issues, detecting hacking attacks, identifying malware and malicious applications, and tracking suspicious and unwanted communications.

- WireShark contains a user-friendly and multi-language interface and supports several network protocols such as TCP/IP, UDP/IP, HTTP, SMTP, FTP, and others. It also supports network capture tools such as WinPcap, Npcap, AirPcap, Dag, and others.

- WireShark works by capturing the flowing data packets in the computer network and analyzing them. It analyzes the contents of the packets and displays them in a detailed manner, showing the address, time, and statistical data related to the packet. Users can also display the data packets in a detailed and comprehensive way, execute several commands, and navigate through the packets.

- WireShark can be used to verify network safety, troubleshoot and fix errors, ensure security and detect hacking attacks, identify malware and malicious applications, identify performance issues, and improve them. It can also be used in digital forensic analysis, verifying the safety of data and digital evidence.

- The Wireshark application programming interface provides the ability to execute more precise and detailed analysis and easily access network details provided by your network. It also contains many important and useful features that help in understanding motion across the network. Some of these features are:

- Wireshark Filters

Enable data filtering and display in different ways and formats. Using Wireshark filters allows the analysis of a specific set of motion data based on specific criteria.

- Tracking movement details across the network

Wireshark displays every detail and motion that passes through your network. You will see all binary data transmitted between different hosts, including routing cycles.

- Providing the opportunity to obtain a large number of data

Wireshark does not reduce the large amount of data that is transmitted across your network. Instead, it helps collect as much data as possible that has been transmitted and use it to monitor issues.

- In general, WireShark is an essential tool for any specialist in the field of networks and information security. It is easy to use, flexible, and has the ability to analyze network traffic in a detailed and comprehensive manner. It also provides support for many protocols and various network capture tools.
