Which network tool allows for the analysis of traffic in real-time?

Tcpdump
Wireshark
Nessus
Netcat

The correct answer is: Wireshark

Wireshark is a powerful network protocol analyzer that captures and displays packets of data being transmitted over a network in real-time. This capability allows network administrators and cybersecurity professionals to closely monitor network traffic, analyze patterns, diagnose issues, and troubleshoot connectivity problems as they occur. Within Wireshark, users can apply various filters to focus on specific types of traffic or protocols, making it easier to dissect network communications. Additionally, its user-friendly interface allows for quick navigation and thorough examination of the data streams, providing insights into network behaviors and potential security threats. While Tcpdump is also a network packet capture tool, it operates primarily through the command line and can capture traffic in real-time, but lacks the graphical interface that Wireshark offers for comprehensive traffic analysis. Nessus, on the other hand, is a vulnerability scanner, focusing on assessing security vulnerabilities rather than analyzing real-time traffic. Netcat is a network utility used for reading from and writing to network connections using TCP or UDP, but it does not provide real-time analysis of traffic in the same way as Wireshark.
