Advanced Network Troubleshooting with Wireshark Training Course

The purpose of this course is to provide participants with foundational knowledge of the Wireshark protocol analyzer, essential for effective network troubleshooting. The curriculum focuses on achieving a deep understanding of the tool, which serves as the basis for its practical application in network diagnostics. The course begins with an introduction to packet capturing, capture and display filters, statistical features, and the basics of the expert system. By the end of the course, participants will be equipped to perform basic troubleshooting in small to medium-sized networks. This training is designed to align with public sector workflows and governance requirements for government. The course combines theoretical instruction with classroom exercises and hands-on labs.

This course builds upon the foundational skills introduced in the "Basic Network Troubleshooting Using Wireshark" course, designed to equip participants with advanced capabilities for network troubleshooting. It offers an in-depth understanding of network behavior and issues, as well as the techniques to identify and resolve security and complex application problems. The curriculum is structured around theoretical instruction, classroom exercises, and hands-on laboratory sessions, ensuring a comprehensive learning experience for government professionals.

Wireshark is a free, open-source packet analyzer utilized for troubleshooting network issues. Network packet analysis involves examining, in real-time, the raw data transmitted and received over a network interface. This technique is essential for diagnosing network configuration and application problems. In this instructor-led, live training (onsite or remote), participants will learn advanced techniques for troubleshooting the functionality and performance of networks and their applications. Building on the foundational course "Network Troubleshooting with Wireshark," which primarily focuses on common HTTP applications, this training expands to cover a broader range of 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 resolve network security issues using the Wireshark Command Line Interface (CLI). - Troubleshoot applications that use protocols beyond HTTP, including HTTPS, FTP, mail, DNS, and others. - Diagnose network connection problems in enterprise applications such as databases and Remote Procedure Call (RPC) services. - Address connection issues in media applications like Voice over Internet Protocol (VoIP) and streaming services. - Utilize network forensics to trace and detect security vulnerabilities. **Audience** - Network engineers - Network and computer technicians **Format of the Course for Government** - Part lecture, part discussion, with exercises and extensive hands-on practice.

Network packet analysis is a technique used to monitor, in real time, the raw data transmitted and received over a network interface. This method is essential for diagnosing issues related to network configuration and application performance. Wireshark, a free and open-source packet analyzer, is widely utilized for government and other organizations to troubleshoot such network challenges.

In this instructor-led, live training, participants will learn how to use Wireshark to evaluate the functionality and performance of a network, as well as the efficiency of various networked applications. Participants will gain an understanding of network troubleshooting principles and practice techniques for capturing and analyzing TCP/IP request and response traffic between different clients and servers.

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

• Analyze network functionality and performance in diverse environments under varying conditions
• Determine whether instances of different server applications are operating within acceptable parameters
• Identify primary sources of network performance issues
• Diagnose and resolve the most common causes of performance problems in TCP/IP communications
