Basic Network Troubleshooting Using Wireshark Training Course

This curriculum is tailored for network engineers and technicians who possess foundational proficiency with Wireshark and seek to master advanced traffic analysis methodologies. Participants will acquire the skills necessary to diagnose performance, application, and security challenges—encompassing VoIP, DNS, database connectivity, and potential cyberattacks—by leveraging command-line utilities, sophisticated filtering capabilities, and forensic approaches. This instruction emphasizes practical application grounded in authentic enterprise network environments for government professionals.

Wireshark is a complimentary open-source packet analyzer employed to diagnose network irregularities. Network packet analysis enables the real-time examination of raw data transmitted and received across network interfaces, supporting the resolution of configuration errors and application-related issues.

This instructor-led live training, available either onsite or remotely, equips participants with advanced methodologies for evaluating the functionality and performance of networks and their associated applications. Building upon the foundational concepts of "Network Troubleshooting with Wireshark," which concentrates on standard HTTP applications, this session expands to address protocols and connection mediums such as Wi-Fi, HTTPS, SMTP, enterprise systems, and others. This curriculum is designed to provide essential tools for government entities managing complex infrastructures for government operations.

Upon completion of this instruction, participants will be capable of:

• Identifying and resolving network security vulnerabilities via the Wireshark command-line interface
• Diagnosing applications utilizing protocols beyond HTTP, encompassing HTTPS, FTP, email, DNS, and similar services
• Addressing connectivity challenges within enterprise applications, including databases and remote procedure calls (RPC)
• Resolving connection difficulties in media-based applications such as Voice over IP (VoIP) and streaming services
• Utilizing network forensics to trace and identify potential security incidents

Audience

• Network engineers
• Network and computer technicians

Format of the Course

• The session combines lectures with interactive discussions, exercises, and extensive hands-on practice.
