Capturing packets is easy, but making sense of them isn’t. This course will teach you the fundamentals of packet analysis. You’ll learn all about common protocols, how to troubleshoot network issues, and how to investigate security incidents at the packet level. It’s easy to fire up Wireshark and capture some packets…but making sense of them is another story. There’s nothing more frustrating than knowing the answers you need lie in a mountain of data that you don’t know how to sift through. That’s why I wrote the first Practical Packet Analysis book a decade ago. That book is now in its third edition, has been translated to several languages, and has sold over 25,000 copies. Now, I’m excited to create an online course based on the book. The Practical Packet Analysis online course is the best way to get hands on visual experience capturing, dissecting, and making sense of packets.
