A challenge of encryption for networking professionals is that the same technology that protects data, makes it more difficult to get visibility into traffic and potential networking issues. “One trend has been to just shove everything as JSON over HTTP and for better or worse that’s how a lot of computers talk nowadays,” Combs said.Īnother network trend that has emerged over the last two decades is the move towards encrypting the majority of network traffic in order to help improve security and provide data privacy. Network traffic in 2023 isn’t the same as it was in 1998 when Wireshark was first built and the open source project has been continuously iterating to stay ahead of network traffic trends. Wireshark is commonly used to help analyze network performance, troubleshoot issues and can also be helpful in identifying potential security risks as well. The technology supports many types of connections including wired Ethernet, Wi-Fi, and Bluetooth, as well as an exhaustive range of networking protocols. Wireshark captures and analyzes network traffic in real-time.
Beyond the basic functionality, Combs noted that there are upwards of 5 million lines of code in Wireshark providing features for protocol analysis and network traffic observability. Why Wireshark Still Matters Decades After It was CreatedĪll network traffic that flows over a wired or wireless interface, makes use of some kind of protocol.Ĭombs explained that what Wireshark does is take the very low level network-based packet information and displays it in a form that humans can understand. However, today the project has moved to the new Wireshark Foundation, which is a nonprofit open source organization designed to help grow the technology, expand contributions, and support further usage. In 2021, he moved to Sysdig, which has been the lead sponsor the last several years. In 2006 Combs was working at CACE Technologies, which was the lead sponsor, until the company was acquired by Riverbed in 2010. From its inception, the technology was available as open source, though it has followed a somewhat meandering path of corporate sponsorship as the project’s founder Gerald Combs has changed jobs. Wireshark got its start back in 1998, originally known as Ethereal and was rebranded in 2006.
The Wireshark network protocol analyzer has been used by networking professionals for the last two decades and today the technology is finally getting its own open source foundation.
