Wireshark Essentials (CS8506)

This course introduces the Wireshark network analyzer to IT professionals across multiple disciplines.

It starts off with the installation of Wireshark, before gradually taking you through your first packet capture, identifying and filtering out just the packets of interest, and saving them to a new file for later analysis. The subsequent modules will build on this foundation by covering essential topics on the application of the right Wireshark features for analysis, network protocols essentials, troubleshooting, and analyzing performance issues. Finally, the course focuses on packet analysis for security tasks, command-line utilities, and tools that manage trace files.

Upon finishing this course, you will have successfully added strong Wireshark skills to your technical toolset and significantly increased your value as an IT professional.
