Basic Terms of Networking5:36
Network layer manages options pertaining to host and network addressing, managing sub-networks, and internetworking.Ethical hacking is legal because the hacker has full, expressed permission to test the vulnerabilities of a system. An ethical hacker operates within constraints stipulated by the person or organization for which they work, and this agreement makes for a legal arrangement. An ethical hacker is like someone who handles quality control for a car manufacturer. They may have to try to break certain components of the vehicle such as the windshield, suspension system, transmission, or engine to see where they are weak or how they can improve them. With ethical hacking, the hacker is trying to “break” the system to ascertain how it can be less vulnerable to cyberattacks. However, if an ethical hacker attacks an area of a network or computer without getting expressed permission from the owner, they could be considered a gray hat hacker, violating ethical hacking principles.
Reference Models0:24
A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it.

What are the different types of hackers?

The different types of hackers include white hat hackers who are ethical hackers and are authorized to hack systems, black hat hackers who are cybercriminals, and grey hat hackers, who fall in-between and may not damage your system but hack for personal gain. There are also red hat hackers who attack black hat hackers directly. Some call new hackers green hat hackers. These people aspire to be full-blown, respected hackers. State-sponsored hackers work for countries and hacktivists and use hacking to support or promote a philosophy. Sometimes a hacker can act as a whistleblower, hacking their own organization in order to expose hidden practices. There are also script kiddies and blue hat hackers. A script kiddie tries to impress their friends by launching scripts and download tools to take down websites and networks. When a script kiddie gets angry at…
OSI Reference Model10:45

Description

Welcome to "Wireshark | Network Traffic Analysis & Packet Capture Course" course.

Networking | Learn packet capture, network analysis & troubleshooting with Wireshark for better Network & Cyber security

Wireshark 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.

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.
