Network Sniffing Tool

Abstract -In today's interconnected digital landscape, network security and traffic monitoring are critical for ensuring the integrity, confidentiality, and availability of data. A Network Sniffing Tool is a utility designed to capture, analyze, and log packets transmitted over a network. This project presents the design and implementation of a lightweight and efficient network sniffing tool capable of real-time packet inspection, protocol analysis, and traffic visualization. Developed using Python and libraries such as Scapy and Wireshark’s TShark backend, the tool provides insights into network behavior by detecting anomalies, unauthorized access, and potential vulnerabilities. It supports filtering by protocol types (TCP, UDP, ICMP, etc.), source/destination IPs, and ports, thus enabling targeted traffic monitoring. The tool can be utilized for both educational purposes and as a diagnostic aid for network administrators. Emphasis is placed on user-friendly interfaces, logging mechanisms, and adherence to ethical use standards. This work contributes to the growing need for accessible and effective cybersecurity instrumentation.
