Understanding network latency and how to locate the source.

Techniques for carving files from packet streams.

Troubleshooting connectivity issues at the packet level.

Normal and abnormal stimulus and response patterns for common protocols.

How to interpret common application layer protocols like HTTP, DNS, SMTP, and more.

How to interpret common network and transport layer protocols like IPv4, IPv6, ICMP, TCP, and UDP.Techniques for capturing packets to make sure you’re collecting the right data.Reducing capture files with Berkeley packet filters and Wireshark display filters.How to analyze packets on the command line with tshark and tcpdump.Basic and advanced analysis features of Wireshark.How to interpret packet data at a fundamental level in hexadecimal or binary.How networking works at the packet level.Whether you’ve never capture packets before or you have and you struggle to manipulate them to effectively achieve your goals, this course will help you get over the hump. The Practical Packet Analysis course is perfect for beginners to intermediate analysts, but seasoned pros will probably learn a few useful techniques too. This class will help you build those skills through a series of expert-led lectures, scenario-based demonstrations, and hands-on lab exercises. The ability to understand packets is a critical skill for network engineers, system administrators, security analysts, forensic investigators, and programmers alike. Everything you’ll learn is something you can directly apply to the job you have, or the job you want. Practical Packet Analysis takes a fundamental approach by exploring the concepts you need to know without all the fluff that is normally associated with learning about network protocols.

The Practical Packet Analysis online course is the best way to get hands on visual experience capturing, dissecting, and making sense of packets. Now, I’m excited to create an online course based on the book. That book is now in its third edition, has been translated to several languages, and has sold over 25,000 copies. That’s why I wrote the first Practical Packet Analysis book a decade ago. 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. It’s easy to fire up Wireshark and capture some packets…but making sense of them is another story.
