🎯 Project Overview

This solution revolutionizes campus network security by implementing Identity as Network Perimeter architecture. Instead of traditional location-based security, user identity (admission number) becomes the primary security boundary, seamlessly integrated with TP-Link Omada infrastructure.

Key Innovation

• WHO you are determines network access, not WHERE you connect
• Single admission number controls all campus systems
• TP-Link hardware automatically assigns VLANs based on user identity
• Real-time network access control and monitoring

✨ Features

🔐 Zero Trust Security

• Identity-centric access control - Every network decision based on verified admission number
• Role-based VLAN assignment - Students, Faculty, Admins get appropriate network segments
• Complete audit trail - All activities logged with user identity

🌐 Network Access Control (NAC)

• RADIUS integration - Industry-standard authentication with TP-Link Omada
• Dynamic VLAN assignment - Automatic network segmentation by user role
• Session management - Real-time monitoring and control of network sessions

👨‍💼 Admin Management

• Real-time user approval - Admins can approve/block network access instantly
• Live session monitoring - See all active network sessions by user identity
• Keycloak integration - Direct user management with real names and emails

📱 User Experience

• Single Sign-On (SSO) - One login across all campus systems
• Automatic network access - No manual VLAN configuration required
• Multi-portal support - LMS, Library, Admin unified under one identity

🚀 Quick Start

Prerequisites

- Node.js 18+
- Docker & Docker Compose
- Git

Installation

1. Clone the repository

git clone https://github.com/your-username/tp-link-campus-identity
cd tp-link-campus-identity

2. Start Keycloak

cd keycloak
docker-compose up -d

3. Install dependencies for all portals

# LMS Portal
cd frontend/lms && npm install

# Library Portal  
cd ../library && npm install

# Captive Portal
cd ../captive-portal && npm install

# Admin Dashboard
cd ../admin-dashboard && npm install

4. Start all services

# Terminal 1 - LMS (Port 3000)
cd frontend/lms && npm run dev

# Terminal 2 - Library (Port 3001) 
cd frontend/library && npm run dev

# Terminal 3 - Admin (Port 3002)
cd frontend/admin-dashboard && npm run dev

# Terminal 4 - Captive Portal (Port 3003)
cd frontend/captive-portal && npm run dev

5. Setup Keycloak

• Visit: http://localhost:8080
• Login: admin/admin
• Import realm configuration from keycloak/campus-realm.json

🎮 Usage

For Students

1. Connect to campus WiFi
2. Captive portal appears automatically
3. Login with admission number
4. Automatically assigned to student VLAN with appropriate bandwidth

For Admins

1. Access admin dashboard: http://localhost:3002
2. View real-time user sessions and network access
3. Approve/block users with instant network impact
4. Monitor complete audit trail

Testing the System

1. Register test users in Keycloak with different roles
2. Access portals with different users to see role-based access
3. Use admin dashboard to approve/block users in real-time
4. Check network monitor at http://localhost:3003/monitor
