What packet sniffing tool is used by forensic specialists to interactively browse live network traffic?

1. Tcpdump

2. Wireshark

3. EtherApe

4. NetWitness

The correct answer is: Wireshark

Wireshark is widely recognized as a powerful packet sniffing tool that allows forensic specialists to interactively analyze live network traffic. Its user-friendly graphical interface provides detailed insights into the packets being transmitted over a network in real-time. Forensic analysts use Wireshark to capture network packets, decode protocols, and investigate anomalies, helping them uncover potential security incidents or unauthorized activities. The tool's ability to filter and display packets dynamically makes it invaluable for conducting in-depth analyses of network traffic patterns and identifying any irregularities or malicious behavior. Furthermore, Wireshark supports a vast array of protocols, which enhances its versatility in different forensic investigations. Other tools like Tcpdump, while effective for capturing packet data, primarily operate in command-line environments and may not provide the same level of interactive capabilities or visual representation of the traffic as Wireshark. EtherApe is more focused on visualizing traffic flows and network topology than detailed packet analysis, and NetWitness is geared towards more comprehensive network security monitoring rather than direct packet inspection. Thus, Wireshark stands out as the preferred tool for forensic specialists due to its detailed, visual, and interactive capabilities in monitoring live network traffic.
