Unauthorized Device Detection Web Application

Description

This project is a lightweight web-based network security tool that detects and flags unauthorized devices connected to a local Wi-Fi or LAN network.

It scans the network for all connected devices, retrieves their IP and MAC addresses, and compares them with a whitelist of authorized devices.
Unknown devices are flagged as unauthorized and shown on a simple web dashboard, where the admin can easily whitelist trusted devices.

This project demonstrates how real-time network monitoring can be achieved using basic network commands (Ping & ARP) and Flask web integration.
