Welcome guys my name is Anwer Khan and I will be your instructor throughout this course. In this course we will talk straight to the point. Therefore, we will cover more in less time.

First, Did you know that being able to understand what's on the network is considered a superpower? It's true. Packet analysis helps you to understand the traffic on your network so you can identify latency issues and actively monitor the network for attacks.

Wireshark is a free and open-source packet analyzer. It is used for network troubleshooting, analysis, software and communications protocol development, and education.

Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and standard across many commercial and non-profit enterprises, government agencies, and educational institutions.

In this course, I'll provide an overview and benefits of traffic capture. I'll cover how to download and install on a PC. Then we'll explore the Wireshark interface. I'll cover how to tap into the data stream and use display and capture filters. I'll review the OSI model and encapsulation.

Then we'll do a deep packet analysis of common protocols, such as TCP, IP and DNS. I'll finish with working with the expert system and how to troubleshoot network latency issues.

Should I be worried about Wireshark?

There's no need to worry because Wireshark has got your back. Wireshark allows you to monitor and analyze network traffic. It can accommodate single-home users up to enterprise level users just like any powerful paid software in the market.

When you're finished with this course, you'll be able to immediately put Wireshark to use in your own work.

I invite you to join me on this Wireshark journey.

Let's get started.

Thank you.
