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! What You Will Learn:This course is designed with detailed, structured sections, each focusing on a crucial aspect of network analysis using Wireshark. By the end of this course, you will:Understand network fundamentals and the OSI model in depth.Install and configure Wireshark on both Windows and Linux with ease.Navigate Wireshark’s interface, profiles, and customization options like a pro.Apply advanced filters to isolate and analyze traffic effectively.Examine key protocols, including TCP, UDP, DHCP, DNS, HTTP, and HTTPS.Identify and troubleshoot network issues efficiently and effectively.Identify and mitigate security threats through traffic analysis.This hands-on course will give you the expertise to confidently capture, analyze, and interpret network traffic for troubleshooting, performance optimization, and security enhancement.In this course, you will learn packet capture, protocol analysis, and network troubleshooting using Wireshark. Through hands-on practice and real-world scenarios, you’ll explore essential network protocols like TCP/IP, HTTP, and DNS while mastering Wireshark’s powerful tools. Whether you're a cybersecurity professional, system administrator, or network engineer, this course will equip you with the skills to analyze network traffic, detect security threats, and optimize performance from scratch.What is Wireshark?Wireshark is an open-source network protocol analysis software program, widely considered the industry standard. A global organization of network specialists and software developers supports Wireshark and continues to make updates for new network technologies and encryption methods.How does Wireshark work?Wireshark is a packet sniffer and analysis tool. It captures network traffic from ethernet, Bluetooth, wireless (IEEE.802.11), token ring, and frame relay connections, among others, and stores that data for offline analysis.When should Wireshark be used?Wireshark can be used to understand how communication takes place across a network and to analyze what went wrong when an issue in communication arises.Wireshark helps:Network administrators troubleshoot problems across a networkSecurity engineers examine security issues across a networkQA engineers verify applicationsDevelopers debug protocol implementationsNetwork users learn about a specific protocolWhy would you want to take this course?Our answer is simple: The quality of teachingOAK Academy based in London is an online education company OAK Academy gives education in the field of IT, Software, Design, development in Turkish, English, Portuguese, and a lot of different language on Udemy platform where it has over 2000 hours of video education lessons.
