Which of the following is the correct definition of tcpdump?

Tcpdump is specifically designed for capturing and analyzing network traffic, making it a valuable tool for network security professionals. It operates at the packet level, allowing users to monitor and filter data as it traverses a network interface. This capability is critical for diagnosing network issues, auditing traffic for compliance, and studying potential security threats in real-time.

The essence of tcpdump lies in its ability to interpret packet data, providing insights into the protocols and contents of the traffic being analyzed, which is crucial for anyone involved in network operations and security. Its filtering capabilities enable users to focus on specific traffic patterns or protocols, enhancing its utility as a diagnostic and analysis tool in network environments.
