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 is a continuation of the "Basic Network Troubleshooting Using Wireshark" course and is designed to provide participants with advanced capabilities for network troubleshooting. It offers an in-depth understanding of network behavior and issues, along with the skills to isolate and resolve security and advanced application problems. The course combines theoretical instruction, class exercises, and laboratory sessions to ensure comprehensive learning for government professionals.

Wireshark is a free, open-source packet analyzer utilized for diagnosing and resolving network issues. Network packet analysis involves the real-time examination of raw data transmitted over a network interface, which is essential for identifying and addressing problems related to network configuration and application performance.

In this instructor-led, live training (onsite or remote), participants will acquire advanced techniques for troubleshooting the functionality and performance of networks and their applications. This course builds upon the foundational skills covered in "Network Troubleshooting with Wireshark," which primarily focuses on common HTTP applications. Here, we delve into a broader range of protocols and connection mediums, such as Wi-Fi, HTTPS, SMTP, and enterprise applications.

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 utilize protocols beyond HTTP, including HTTPS, FTP, mail, DNS, and others
• Diagnose and address network connection problems in enterprise applications such as databases and Remote Procedure Calls (RPC)
• Identify and resolve connection issues in media applications like 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

• A combination of lectures, discussions, exercises, and extensive hands-on practice

Network packet analysis is a technique used to examine, in real time, the raw data transmitted and received over a network interface. This method is essential for diagnosing network configuration issues and problems with network applications. Wireshark, a free and open-source packet analyzer, is widely utilized for troubleshooting these types of network challenges.

In this instructor-led, live training, participants will learn how to use Wireshark to assess the functionality and performance of a network, as well as the efficiency of various networked applications. Participants will be introduced to network troubleshooting principles and will 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
• Evaluate whether instances of different server applications are performing satisfactorily
• Identify primary sources of network performance issues
• Detect and resolve the most common causes of performance problems in TCP/IP communications

Audience

• Network engineers
• Network and computer technicians

Format of the Course

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