Which of the following utilities allows you to capture live network traffic and analyze it at your leisure?

Wireshark is a powerful network protocol analyzer that enables users to capture and interactively browse the traffic running on a computer network. This utility is particularly useful in network forensics, troubleshooting, and security analysis.

When you use Wireshark, it captures live data packets as they are transmitted over the network. The captured data can then be analyzed in-depth, allowing users to inspect the details of each packet, such as its source and destination addresses, protocol types, and payload data. Wireshark supports various protocols and can decode these packets, making it easier to understand network communication and identify potential issues or malicious activity.

Other utilities listed serve different purposes. For instance, Sleuthkit is primarily used for digital forensics analysis of storage media, Foremost is a tool designed for file recovery by carving through disk images, and Web Historian is typically used for analyzing web activity rather than live network traffic. As a result, those do not provide the same functionality as Wireshark in terms of capturing and analyzing real-time network activity.
