Description

Welcome to "Wireshark | Wireshark Packet Analysis for Network Security" course.Networking | Learn packet capture, network analysis & troubleshooting with Wireshark for better Network & Cyber securityWireshark is a software tool used to monitor the network traffic through a network interface. It is the most widely used network monitoring tool today. Wireshark is loved equally by system administrators, network engineers, network enthusiasts, network security professionals ,ethical hackers and security researchers.Wireshark is a network packet analyzer. A network packet analyzer presents captured packet data in as much detail as possible.You could think of a network packet analyzer as a measuring device for examining what's happening inside a network cable, just like an electrician uses a voltmeter for examining what's happening inside an electric cable (but at a higher level, of course).In the past, such tools were either very expensive, proprietary, or both. However, with the advent of Wireshark, that has changed. Wireshark is available for free, is open source, and is one of the best packet analyzers available today.Wireshark is the most often-used packet sniffer in the world. Like any other packet sniffer, Wireshark does three things:Packet Capture: Wireshark listens to a network connection in real time and then grabs entire streams of traffic – quite possibly tens of thousands of packets at a time.Filtering: Wireshark is capable of slicing and dicing all of this random live data using filters. By applying a filter, you can obtain just the information you need to see.Visualization: Wireshark, like any good packet sniffer, allows you to dive right into the very middle of a network packet. It also allows you to visualize entire conversations and network streams.Master network traffic analysis with Wireshark!
