About Course
This course offers an in-depth exploration of network traffic analysis through the practical application of Wireshark, the world’s most widely used network protocol analyzer. It is designed for learners who wish to gain a deep and applied understanding of how modern networks operate at the packet level and how to monitor, analyze, and troubleshoot those networks using professional-grade tools.
The course begins with foundational concepts in computer networking, including packet structure, protocol layers (OSI and TCP/IP models), and basic communication flows. Learners are gradually introduced to Wireshark as a diagnostic and investigative tool, focusing on how to properly capture live network traffic, understand packet flows, and apply filters to isolate communication patterns. A significant emphasis is placed on interpreting low-level protocol behavior, such as TCP handshakes, DNS lookups, HTTP transactions, and more.
As students progress, the course moves into advanced techniques such as customizing Wireshark layouts, working with display and capture filters, reconstructing fragmented data streams, and performing security-related investigations. Use cases include detecting failed connections, analyzing slow application behavior, identifying bandwidth misuse, and discovering indicators of compromise (IOCs) during security events.
Throughout the course, real-world scenarios and case studies are used to provide hands-on experience and simulate environments encountered by network administrators, cybersecurity analysts, and protocol developers. By combining technical instruction with practical labs, this course bridges theoretical knowledge with the applied skills necessary to thrive in IT, cybersecurity, and network engineering roles.
Upon successful completion of the course, learners will be able to conduct independent network assessments, troubleshoot complex connectivity problems, and use Wireshark as a core part of their technical toolkit in both operational and security-focused contexts.
