Course content

5 sections27 lectures3h 25m total length
  • TCP/IP vs OSI/Model4:10

    It's hard to really make sense out of Wireshark data unless you have a firm understanding of Networking Basics.  So instead of just throwing you into a tool and saying, "Here's how it works!" I wanted to give you a solid foundation about how computer networks work.  In this quick lecture I kick things off by explaining the two networking models, TCP/IP and OSI Models.  You'll learn how they differ, how TCP/IP won the day but why the OSI Model is still relevant for understanding PCAPs!

  • Application Layers6:32

    So what's up with the Application Layer?  Let's say you're using Chrome to view this video on your mobile phone.  Is the Application Chrome or HTTPS? Try to guess and then test your answer against the knowledge you'll gain in this lecture!  Let's go!

  • Transport Layer9:12

    Yes! Now it's time to quickly get up to speed with the Transport layer (pun intended!.. up to speed.. transport...) lol okay anyway in this lecture you're going to learn all about the layer that makes Wireshark smile.  After finishing this video lesson you'll have a pretty solid understanding of why we need the transport layer.  We'll even dig into the Windows command line so I can show you some handy tricks understanding what happens at this layer.

  • Network Layer2:21

    This is a super fast review of the Network Layer.  Keeping things light and simple so that things don't get too overwhelming with the Data Link layer :)

  • Data Link + Physical Layers10:56

    So in the last lecture we learned that IP addresses help us move packets end-to-end.  But, if that's the case, what's the point of a MAC address?  What would happen if we just left those off, couldn't the packet still get to where it needs to go? Ha! You're about to find out!  This lecture is critical, probably one of the most important in the entire course so you definitely need to listen closely!  I can't wait to see you inside buddy.

  • End-to-End Communication: Putting it Together (Part 1)5:49

    Now I want to connect the dots to help you see the big picture: from clicking a button in your browser to viewing the results.. what happens in between with DNS? What happens across the various TCP/IP and OSI layers?  You're about to find out!  Let's jump in.

  • End-to-End Communication: Three Way Handshake3:32

    The three way handshake.  Yes, we all have heard of SYN, SYN/ACK, ACK but what exactly does that mean? In this quick lecture I'm going to lay out the purpose behind this secret computer handshake and break down exactly what it does and why we need it.  This is a perfect lecture to take if you really want to wow your interviewer! :)

  • End-to-End Communication: Putting it Together (Part 2)3:59

    Now it's time to wrap up the entire network communications process.  I really wanted you to have a confident grasp of network communications before we busted open Wireshark.  Why?  Because anyone can use a tool and click through a GUI, but understanding the protocols and network behavior being displayed in the tool will truly set you apart and make you an invaluable asset to any organization!  So let's go, we are just one lecture away from running our first Wireshark capture!  Yes!

  • Wireshark: First Dive!7:52

    Aww yeah!  Yes! Yes! Yes! This is where stuff starts to get good.  In this lecture we're going to install Wireshark, fire up our browser and then take a nosedive right into the packets.  You're going to see the OSI and TCP/IP models at work right before your eyes!  We're going to break down the three-way handshake inside the packets.  You'll see the ACKs and SYNs and all that good stuff and I'll break down the sequence numbers in even more detail.  You'll also see DNS queries and answers and oh man... there's so much goodness in this lecture... let me stop talking and give you a moment to jump in and taste how good this is!  Let's GO!!

Description

All New For Spring\Summer 2021!

This is the course I wish I had when I was learning about how computer networks work!

You're going to not only learn how to MASTER Wireshark but also gain a deep understanding of computer networks so you can troubleshoot common networking issues and rapidly respond to cybersecurity breaches when a computer gets hacked!

This is the perfect course for anyone who wants to gain true mastery over Wireshark, finally understand how networks work, how to diagnose common network related issues and respond to advanced threat actors who may be in your network. We'll cover some pretty advanced attacks hackers are using to breach organizations and I'll show you how you can use Wireshark, Brim, Suricata, Bro/Zeek and more to bolster your security and keep the bad guys out!

This is a hands on course. It also includes packet captures files you can load into Wireshark and immediately start learning. As always if you have any questions just hit me up on my email address and I’ll be sure to respond (or leave a comment and I’ll jump in and answer your questions!)

We will also be setting up everything in a private local lab so you have complete freedom to experiment and learn.

It's going to be a lot of fun! Let's go! Right! Now!

Yes!
