What is the term for filtering traffic between two specific devices using tools like Wireshark?

The term that accurately describes the process of filtering traffic between two specific devices using tools like Wireshark is "Filtering by Conversation." This technique allows users to focus on the data flow between selected endpoints, making it easier to analyze communication patterns and troubleshoot network issues.

When using Wireshark, for example, one can apply filters that specify the source and destination addresses, which narrows down the traffic to just that conversation. This method proves invaluable in investigations, allowing for a concentrated view of interactions without the clutter of unrelated data.

The other terms presented do not accurately capture this specific method. "Tunneling" refers to a method of encapsulating data to transfer it securely over a different network. "Sessionizing" typically pertains to the process of organizing data into sessions based on certain markers or timings, which is not the same as specifically filtering traffic between devices. "Filtering by Connection" is a bit vague and does not represent the specific technique of isolating traffic from a conversation perspective. Thus, the best choice describing the action taken in Wireshark is indeed filtering by conversation, highlighting its focused approach to network data analysis.
