This is why connecting to a public network such as Starbucks and doing financial transfers or accessing private data is risky. As a bad guy (which I do not recommend), you can sniff network packets and grab information such as credit card purchases. You may use Wireshark as a network engineer or ethical hacker to debug and protect the networks. Wireshark allows you to ‘listen' to a live network (after connecting to it), record, and inspect packets on the move. Wireshark allows you to catch and search each of these packets for details.Ī network engineer's equivalent of a biologist's microscope is Wireshark. You can now understand the significance of Wireshark. Thousands, if not millions, of these data packets are transmitted between the source and destination devices for each data connection. Your machine reassembles these packets to send you the original file.Įach packet includes important information about the devices involved in the packet transfer. When you download a file from the internet, the data is transmitted as packets from the server. When data is transmitted from one device to another, it is divided into smaller units known as packets. ![]() Now that you understand the OSI model, let's look at network packets. If you want to read more about the OSI model, check out this comprehensive essay. The OSI Model classifies network architecture into seven layers:Īpplication, Presentation, Session, Transport, Network, Datalink, and Physical. The Open Systems Interconnection (OSI) paradigm standardises the manner in which two or more computers communicate with one another. While most security systems are command-line-based, Wireshark has an excellent user interface. ![]() Wireshark is now fully open-source, thanks to the global network engineering ecosystem. Most businesses and government agencies also use Wireshark as a primary network analyzer. Wireshark is compatible with all major operating systems. Wireshark was first made available in 1998. Wireshark allows you to dissect network packets at a microscopic level, including detailed information on individual packets. ![]() Wireshark is a network analyzer that allows you to see what is going on with your network.
