Analyzing Network Traffic with Wireshark- A Reflection on Filtering and Data Organization
Working with Wireshark in the lab immersed me in network analysis and troubleshooting.
Using Wireshark Views, Settings, and Filters
Wireshark offers a variety of views, each serving a specific purpose in dissecting network traffic. For instance, the Packet List view summarizes collected packets to show network performance. The Packet Details view examines each packet in detail because it provides protocol-specific information. Packet Bytes are useful for troubleshooting packet faults because they show original data.
The Value of Filters
Filters operate as gatekeepers, ignoring amounts of unnecessary data that consumers may not need for packet analysis. Thus, filters like source and destination IP addresses, protocols, and packet contents eliminate redundancy while evaluating collected data. This method improves efficiency and helps find network events and problems.
Value of Task Demonstration
Wireshark’s views, settings, and filters help organize collected data for studies. I extracted important facts from all preserved network traffic using several viewpoints and filter choices, making my task more efficient. This hands-on activity helped me understand Wireshark’s real-world applications.
Significance of a Ring Buffer
Circular bytes are called ring buffers because they efficiently store fixed-size data. When full, the buffer overwrites older data with fresh ones. Since it is cyclic, a new packet is always added, and the old one is written over; therefore, it does not need to be resized or managed manually.
Application in Wireshark
A Wireshark ring buffer efficiently manages network traffic storage. Configuring Wireshark to use a ring buffer lets it capture packets up to its size (Bullock & Parker, 2017). New packets replace old ones, ensuring continuous packet capture and preventing buffer overflow. Security analysis and network troubleshooting require constant network traffic monitoring, making this feature crucial.
Evident Lab Use
Wireshark’s lab configuration helped me grasp why and how to record packets without interruptions for storage resource management and tool functioning. I saw firsthand what happens when a “ring buffer” technology tracks network traffic.
Why Add an HTTP Host Field Column
Increase HTTP Traffic Visibility
Adding an HTTP host column to Wireshark enhances HTTP traffic visibility by displaying HTTP request and response host fields. These should be added to Wireshark because the host field gives the domain name of the web server accessed, which is useful for examining protocol transactions.
How the Labs Helped in Understanding Tasks
Adding an HTTP host field column to the practical sessions underlined the need for context in network research. When I introduced a host field column to HTTP traffic, I learned how clients talk to servers. Improved visibility helped identify online browsing concerns and improve network analysis.

Question 
In this week’s labs, you captured file sets, conserved drive space using a ring buffer, added the HTTP host field as a column, and created, saved, and applied a DNS capture filter.
Write a 350- to 700-word reflection on your experience completing these tasks. Include the following in your reflection:
