During a routine network analysis, you notice an unusually high amount of traffic coming from a single host. Suspecting a misconfigured application or a potential security threat, you decide to investigate further using Wireshark. You alm to understand the nature of the traffic and identify the protocols involved. Which steps should you take in Wireshark to achieve this? Use the "Statistics" menu to access the "Protocol Hierarchy" statistics to see the distribution of protocols used by the host. Use the "Edit" menu to change the colorization of packets to visually identify suspicious activity. Export the packet capture and send it to a security analyst for further investigation. Immediately apply a display filter for known malicious protocols to see if they are present.

Answer

Use Protocol Hierarchy, apply filters for malicious protocols, adjust colorization, and export capture if needed. Explanation 1. Open Wireshark and Load Capture Start Wireshark and open the packet capture file containing the traffic from the suspicious host. 2. Use Protocol Hierarchy Statistics Go to the "Statistics" menu, select "Protocol Hierarchy" to view the distribution of protocols used by the host. This helps identify which protocols are most prevalent in the traffic. 3. Apply Display Filter for Malicious Protocols Use a display filter to check for known malicious protocols (e.g., `tcp.port == 80` for HTTP or specific malware signatures). This quickly highlights any suspicious activity. 4. Change Packet Colorization Use the "Edit" menu to change color rules for packets, making it easier to visually spot unusual patterns or activities. 5. Export Packet Capture If further analysis is needed, export the packet capture and send it to a security analyst for detailed investigation.
