Introduction

In the digital age, monitoring network traffic is essential for maintaining security, diagnosing issues, and understanding network behavior. Selecting an appropriate network traffic analysis tool enables users to scrutinize data packets and identify potential threats effectively. This paper discusses the selection process for a network traffic analysis tool, describes the data collected from a home network, and demonstrates how such data can be instrumental in threat detection.

Selection of the Network Traffic Analysis Tool

For this analysis, I selected Wireshark as my primary network traffic analysis tool. Wireshark is renowned for its comprehensive features, open-source availability, and extensive user community, making it an ideal choice for both beginners and advanced users. Its rich graphical interface, powerful filtering options, and detailed packet analysis capabilities enable users to dissect network traffic comprehensively. I chose Wireshark because it is widely trusted in cybersecurity circles for its detailed insights and versatility (Agrawal, 2015). Additionally, its ability to capture live network traffic and analyze stored packet captures provides flexibility for varied analysis scenarios.

Why I Selected Wireshark

The primary reasons for choosing Wireshark include its extensive support for multiple protocols, ease of use, and free accessibility. Its robust filtering capabilities allow users to isolate specific types of traffic—such as HTTP requests, TCP connections, or suspicious packets—making threat detection more manageable. Furthermore, Wireshark’s active development community ensures continuous enhancement and support. With its widespread adoption in cybersecurity, learning Wireshark also aligns with best practices in network security analysis (Huang et al., 2018).

Data Collected from the Home Network

Using Wireshark, I captured network traffic over a period of approximately 30 minutes on my home Wi-Fi network. The data comprised various traffic types, including browsing activities, software updates, and background processes. Notably, I observed standard protocols such as HTTP, HTTPS, DNS, and some ARP requests. The captured data included packet headers and payloads, which revealed details such as source and destination IP addresses, ports, and protocol-specific information.

The data enabled me to identify normal network operations as well as potential anomalies. For example, unusual DNS requests and connections to unfamiliar IP addresses flagged potential privacy concerns or malicious activity. The detailed packet inspection provided insights into data flow, session establishment, and potential vulnerabilities or intrusions.

Using Wireshark to Detect Threats

The collected data provides a foundation for threat detection. By analyzing packet metadata, I identified some indicators of suspicious activity. For instance, repeated connection attempts to obscure or unfamiliar IP addresses could signify scanning behavior or malware communication channels. Additionally, detecting unencrypted data transfers or unusual port activity can signal security risks (Zhou et al., 2019).

Wireshark’s filtering capabilities were essential for isolating these anomalies. For example, applying filters for uncommon port activity or specific IP ranges helped highlight potential threats. Packet payload analysis allowed me to identify unencrypted credentials or other sensitive data being transmitted insecurely.

Screen Shots and Data Summary

Included in this analysis are several screenshots demonstrating Wireshark in action:

- A view of ongoing network traffic with filters applied to isolate suspicious packets.

- Packet details showing protocol, source/destination IP addresses, and payloads.

- Collective data summaries illustrating traffic volumes, most active connections, and protocol distributions.

These visuals help contextualize the data and demonstrate how the tool facilitates threat identification.

Conclusion

Selecting Wireshark as my network analysis tool provided valuable insights into my home network traffic. The data collected enabled me to distinguish normal network activity from potential threats, emphasizing the importance of regular network monitoring. The detailed packet analysis capabilities of Wireshark facilitate early detection of malicious activities, making it a vital tool for network security enthusiasts and professionals alike.
