This usually involves reading and writing data transmitted over an unsecure or compromised network. Wireshark can also be used as a tool for hackers. Students learning about network protocols, network (in)security, and more. Quality-assurance engineers who want to assess the quality of network applications.ĭevelopers who need to debug network protocols. Network security engineers seeking to discover misuse or vulnerabilities. Network administrators investigating issues (e.g.

Capture and Dumpcap Capture Engine can also be used to read packets depending on the user’s platform.įrom the very beginning, Wireshark has been designed to be an educational and professional tool for network analysis.

Wiretap reads and writes captured packets from hard disk storage.

Enhanced Packet Analyzer (EPAN) analyzes the network packets using the four APIs shown in the figure (e.g.

Data can be captured from Wi-Fi, Ethernet, Bluetooth and more. The network traffic gets forwarded to the CPU, and Wireshark is able to store and display this data using a Graphical User Interface. This allows your NIC to capture all packets in your network regardless of whether they are intended for your device. Wireshark places your device’s NIC into “promiscuous mode”. Usually your NIC will only capture packets that are destined for your MAC address. Every NIC has a unique MAC address assigned to it at the time of production. The NIC is responsible for connecting your computer to a network. In your computer, you have a piece of hardware called a Network Interface Controller (NIC). Once captured, the data can be presented into a human readable format (assuming it is not encrypted). You can specify whether you would like to capture the entire packet or only the information component. Wireshark is capable of intercepting and logging these packets as they flow across a network. Whereas the address and postage stamp are part of the information component. It is common to compare a packet to an envelope.

It contains details such as the sender’s IP address, the recipient’s IP address, how to send the data, and more. The information component is kind of like metadata. The payload can be thought of as the data itself (e.g. Each packet has two components: information and payload. At the Network layer, data is divided into smaller components called packets. For a large number of cases, data is too large to be sent as a whole.

Application Layer -> Data in its full formįor the purposes of understanding Wireshark, we will concern ourselves with the Network layer (number 3).

Depending on which layer you are referring to, data can be represented in one of five different ways: The OSI Model is divided into 7 layers and is meant to provide a conceptual understanding of how data is transmitted across a network. Before diving into the details of what it does, let’s first understand what a packet is.

Wireshark is a packet analyzer (or “sniffer”).

Wireshark’s source code can be found on Gitlab and the application can be downloaded from Wireshark’s official website. Since its inception, over 700 people from around the world have contributed to the project. Today, Wireshark is one of the most widely used network protocol analyzers, and remains freely available for anyone to use. In 2006, the project changed its name to Wireshark. Over time, the project gained contributors who implemented new functionality to cover different use cases related to network analysis. The project steadily gained traction among network professionals who were looking for a tool to solve similar problems. (1)Ĭombs made Ethereal’s code open-source and the application was freely available for anyone to use or modify.

Disappointed by the lack of available options at the time, he decided to create his own. In 1998, Gerald Combs wanted a tool to help him investigate network problems and learn more about networking in general.
