The tool sees TCP data in the same way as that of the application layer. Use this tool to find passwords in a telnet session or to interpret a data stream.

• A. Follow TCP Stream in Wireshark
• B. DerpNSpoof
• C. DNS cache poisoning
• D. SteelCentral Packet Analyzer

Answer: (A)

Reassembling the actual flow of data from a TCP connection lets you see exactly what the application exchanged, byte by byte, in the order sent. Following a TCP stream in Wireshark reconstructs the complete conversation for one connection and presents it as a readable stream of text. This is especially revealing with telnet, where credentials and commands are sent in plaintext; by viewing the reassembled stream you can read passwords and other sensitive data just as the application would have seen them. It’s also a handy way to interpret any data stream from a TCP session, because you get the full, ordered payload rather than isolated packets. The other tools listed don’t provide this targeted stream-reassembly view. One is focused on DNS spoofing, another on cache poisoning, and the remaining is a general packet analyzer with different primary features. The specific capability to reconstruct and read the TCP conversation makes following the TCP stream the best fit.
