A user-friendly network monitoring system that detects illegal activity, identifies operating systems, and visualizes LAN computers in real time.
Network Analyzer is a full-stack system for monitoring a local area network (LAN). It provides real-time insights into connected devices, alerts on suspicious behavior, and allows admins to set "illegal" applications or web domains to track.
🔐 This project was developed as my final high school project for the Israeli Bagrut exam in Computer Science (10 units) at Amos De-Shalit High School, Rehovot.
