Web Dashboard Security

The DecentIoT web dashboard is built with enterprise-grade security and complete data ownership. This guide covers all security measures for the web platform, authentication systems, and best practices for secure deployments.

🔒 Web Security Architecture

Core Security Principles

🛡️ End-to-End Encryption - All web communication uses HTTPS/TLS
🏠 Your Own Infrastructure - Dashboard runs on your servers
🔐 Multi-Factor Authentication - Secure user authentication
🚫 No Third-Party Tracking - Complete privacy protection
🔍 Audit Logging - Comprehensive activity monitoring

🔐 Authentication & Authorization

User Authentication System

Multi-Factor Authentication (MFA)

✅ Email/Password Authentication - Primary authentication method
✅ Two-Factor Authentication (2FA) - Optional TOTP support
✅ Session Management - Secure session handling with expiration
✅ Password Policies - Strong password requirements

Role-Based Access Control (RBAC)

// Example role-based permissions
const userRoles = {
  admin: {
    permissions: ['create_project', 'manage_users', 'view_analytics', 'system_settings']
  },
  user: {
    permissions: ['create_project', 'manage_devices', 'view_dashboard']
  },
  viewer: {
    permissions: ['view_dashboard']
  }
};

Session Security

Secure Session Management

🔒 HTTP-Only Cookies - Prevent XSS attacks
🔒 Secure Flag - HTTPS-only cookies
🔒 SameSite Protection - CSRF attack prevention
🔒 Session Expiration - Automatic timeout and renewal

JWT Token Security

// Secure JWT implementation
const jwtConfig = {
  algorithm: 'RS256',           // Asymmetric encryption
  expiresIn: '1h',             // Short expiration time
  issuer: 'decentiot-dashboard', // Token issuer
  audience: 'decentiot-users'   // Token audience
};

🛡️ Data Protection & Privacy

Data Encryption

At-Rest Encryption

🔐 Database Encryption - All data encrypted in database
🔐 File System Encryption - Encrypted file storage
🔐 Backup Encryption - Encrypted backup systems
🔐 Key Management - Secure encryption key handling

In-Transit Encryption

🔐 HTTPS/TLS 1.3 - Modern encryption protocols
🔐 Certificate Pinning - Prevent man-in-the-middle attacks
🔐 HSTS Headers - Force HTTPS connections
🔐 Perfect Forward Secrecy - Unique session keys

Data Privacy Controls

User Data Management

🚫 No Data Collection - No tracking or analytics
🚫 No Third-Party Sharing - Data never leaves your infrastructure
🚫 No Advertising - No ad networks or tracking pixels
✅ Data Export - Users can export their data
✅ Data Deletion - Complete data removal on request

// GDPR compliance features
const privacyFeatures = {
  dataMinimization: true,        // Collect only necessary data
  purposeLimitation: true,       // Use data only for stated purposes
  storageLimitation: true,       // Automatic data expiration
  rightToAccess: true,          // Data access requests
  rightToRectification: true,   // Data correction requests
  rightToErasure: true,         // Right to be forgotten
  dataPortability: true         // Data export functionality
};

🌐 Network Security

HTTPS Configuration

SSL/TLS Setup

# Nginx SSL configuration
server {
    listen 443 ssl http2;
    server_name your-dashboard.com;
    
    # SSL Configuration
    ssl_certificate /path/to/certificate.crt;
    ssl_certificate_key /path/to/private.key;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512;
    ssl_prefer_server_ciphers off;
    
    # Security Headers
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    add_header X-Frame-Options DENY always;
    add_header X-Content-Type-Options nosniff always;
    add_header X-XSS-Protection "1; mode=block" always;
    add_header Referrer-Policy "strict-origin-when-cross-origin" always;
}

Security Headers

Content Security Policy (CSP)

<!-- CSP Header -->
<meta http-equiv="Content-Security-Policy" 
      content="default-src 'self'; 
               script-src 'self' 'unsafe-inline'; 
               style-src 'self' 'unsafe-inline'; 
               img-src 'self' data: https:; 
               connect-src 'self' wss: https:;">

Additional Security Headers

🛡️ X-Frame-Options - Prevent clickjacking attacks
🛡️ X-Content-Type-Options - Prevent MIME type sniffing
🛡️ X-XSS-Protection - XSS attack prevention
🛡️ Referrer-Policy - Control referrer information

🔍 Input Validation & Sanitization

Frontend Validation

Client-Side Validation

// Input validation example
const validateInput = (input) => {
  // Sanitize HTML
  const sanitized = DOMPurify.sanitize(input);
  
  // Validate length
  if (sanitized.length > 1000) {
    throw new Error('Input too long');
  }
  
  // Validate format
  if (!/^[a-zA-Z0-9\s\-_]+$/.test(sanitized)) {
    throw new Error('Invalid characters');
  }
  
  return sanitized;
};

Backend Validation

Server-Side Validation

// Express.js validation middleware
const validateProjectData = (req, res, next) => {
  const { name, description } = req.body;
  
  // Validate required fields
  if (!name || name.trim().length === 0) {
    return res.status(400).json({ error: 'Project name required' });
  }
  
  // Validate length
  if (name.length > 100) {
    return res.status(400).json({ error: 'Project name too long' });
  }
  
  // Sanitize input
  req.body.name = sanitizeHtml(name.trim());
  req.body.description = sanitizeHtml(description || '');
  
  next();
};

🚨 Security Monitoring & Logging

Audit Logging

Comprehensive Logging

// Security event logging
const logSecurityEvent = (event, user, details) => {
  const logEntry = {
    timestamp: new Date().toISOString(),
    event: event,
    userId: user.id,
    ipAddress: req.ip,
    userAgent: req.get('User-Agent'),
    details: details
  };
  
  // Log to secure audit system
  auditLogger.info(logEntry);
  
  // Alert on suspicious activity
  if (isSuspiciousEvent(event, details)) {
    securityAlert(logEntry);
  }
};

Real-Time Monitoring

Security Alerts

🔍 Failed Login Attempts - Multiple failed authentication attempts
🔍 Unusual Access Patterns - Access from new locations or times
🔍 Data Export Requests - Large data export activities
🔍 Admin Actions - Sensitive administrative operations

Monitoring Dashboard

// Security monitoring metrics
const securityMetrics = {
  failedLogins: 0,
  successfulLogins: 0,
  dataExports: 0,
  adminActions: 0,
  suspiciousActivity: 0
};

🔧 Secure Deployment Practices

Environment Security

Production Environment

🔒 Separate Environments - Dev, staging, and production isolation
🔒 Environment Variables - Secure configuration management
🔒 Secrets Management - Encrypted secrets storage
🔒 Access Control - Limited production access

Container Security

FROM node:18-alpine

# Create non-root user
RUN addgroup -g 1001 -S nodejs
RUN adduser -S nextjs -u 1001

# Set working directory
