TCP/IP Network Traffic Analysis with Wireshark

 35 Hours

Wireshark is a free open source packet analyzer used for troubleshooting network issues. Network packet analysis is a technique used to view, in real time, the raw data sent and received over a network interface. This is useful for troubleshooting network configuration and network application problems.

In this instructor-led, live training (onsite or remote), participants will learn advanced techniques for troubleshooting the functionality and performance of a network and its applications. This course is an extension of "Network Troubleshooting with Wireshark", which focuses primarily on common HTTP applications. In this training, we consider protocols and connection mediums such as Wi-Fi, HTTPS, SMTP, enterprise applications and more.

By the end of this training, participants will be able to:

  • Isolate and solve network security issues using the Wireshark CLI
  • Troubleshoot applications that use protocols beyond HTTP, including HTTPS, FTP, mail, DNS, etc.
  • Troubleshoot network connection problems in enterprise applications such as databases, RPC, etc.
  • Troubleshoot connection problems in media applications such as VoIP and streaming
  • Use network forensics to trace and detect security issues

Audience

  • Network engineers
  • Network and computer technicians

Format of the Course

  • Part lecture, part discussion, exercises and heavy hands-on practice
