Wireshark: Packet Analysis and Ethical Hacking
Beginner 12 hours English Completion Certificate Certificate
About this course
This course teaches Wireshark from the ground up: capturing packets on live networks, writing display filters to isolate traffic, dissecting TCP/IP, HTTP, DNS, and TLS protocols, and using Wireshark for both network troubleshooting and security analysis.
Students analyze real packet captures — investigating slow network connections, DNS poisoning attacks, cleartext credential theft, and malware command-and-control traffic. The course builds the packet-level understanding that separates intermediate from advanced network and security engineers.
What you'll learn
Capture and filter network traffic using Wireshark's capture and display filters
Dissect and interpret TCP/IP, HTTP, DNS, DHCP, and TLS protocols
Identify network performance issues including retransmissions and latency
Detect security threats including credential theft and C2 traffic in packet captures
Export data from packet captures for further analysis
