Wireshark is a powerful and widely utilized network protocol analyzer that allows users to capture and inspect network traffic in real-time. It’s particularly valuable for troubleshooting network issues because it provides detailed insights into the packets of data transmitted over a network. By analyzing this data, users can identify problems such as bandwidth bottlenecks, unauthorized access, or misconfigured network devices.

One of the key features of Wireshark is its ability to decode various network protocols and present the information in a user-friendly interface. This capability helps instructors and students in network management and system security courses understand network behavior and diagnose issues effectively. With its filtering and searching capabilities, users can focus on specific traffic flows, making it an essential tool for any cybersecurity professional involved in monitoring and protecting network integrity.

In contrast, the other tools mentioned serve different purposes. The National Vulnerability Database (NVD) is a repository of vulnerability management data, while Common Vulnerabilities and Exposures (CVE) provides a list of publicly known cybersecurity vulnerabilities. Firewalls, on the other hand, act as security systems that monitor and control incoming and outgoing network traffic based on predetermined security rules but do not assist in troubleshooting network traffic. Hence, Wireshark stands out as the most appropriate choice for
