​
Current Authentication Status

The API currently does not implement authentication or authorization. All endpoints are publicly accessible without credentials.
Based on the source code analysis (server/index.js:1-913), there is:
  • No authentication middleware
  • No API key validation
  • No JWT token verification
  • No user session management
  • No authorization checks
This means any client can:
  • Read all data from any endpoint
  • Create, update, or delete any resource
  • Access data from all collection centers

​
CORS Configuration

The API has CORS enabled for all origins: 
app.use(cors());
This allows requests from any domain, which is suitable for development but should be restricted in production.

​
Security Considerations

​
For Development

The current open API is acceptable for:
  • Local development environments
  • Internal networks behind a firewall
  • Trusted environments with no external access

​
For Production

Do not deploy this API to production without adding authentication.Without authentication, your data is vulnerable to:
  • Unauthorized access and data theft
  • Data manipulation or deletion
  • Spam or abuse
Before deploying to production, implement these security measures:

​
1. Add Authentication Middleware

Implement one of these authentication strategies: Option A: API Key Authentication 
const authenticateApiKey = (req, res, next) => {
  const apiKey = req.headers['x-api-key'];
  if (!apiKey || apiKey !== process.env.API_KEY) {
    return res.status(401).json({ error: 'Unauthorized' });
  }
  next();
};

app.use('/api/*', authenticateApiKey);
Option B: JWT Token Authentication 
import jwt from 'jsonwebtoken';

const authenticateJWT = (req, res, next) => {
  const token = req.headers.authorization?.split(' ')[1];
  if (!token) {
    return res.status(401).json({ error: 'No token provided' });
  }
  
  jwt.verify(token, process.env.JWT_SECRET, (err, user) => {
    if (err) {
      return res.status(403).json({ error: 'Invalid token' });
    }
    req.user = user;
    next();
  });
};

app.use('/api/*', authenticateJWT);

​
2. Restrict CORS Origins

Limit CORS to specific domains: 
app.use(cors({
  origin: process.env.ALLOWED_ORIGINS?.split(',') || 'http://localhost:3000',
  credentials: true
}));

​
3. Add Rate Limiting

Protect against abuse with rate limiting: 
import rateLimit from 'express-rate-limit';

const limiter = rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
});

app.use('/api/', limiter);

​
4. Implement Authorization

Add role-based access control to restrict operations: 
const requireRole = (role) => (req, res, next) => {
  if (!req.user || req.user.role !== role) {
    return res.status(403).json({ error: 'Forbidden' });
  }
  next();
};

// Example: Only admins can delete
app.delete('/api/tickets/:id', requireRole('admin'), async (req, res) => {
  // ... delete logic
});

​
5. Use HTTPS

Always use HTTPS in production to encrypt data in transit:
  • Deploy behind a reverse proxy (nginx, Apache)
  • Use Let’s Encrypt for free SSL certificates
  • Redirect HTTP to HTTPS

​
6. Validate Input

Add input validation to prevent injection attacks: 
import { body, validationResult } from 'express-validator';

app.post('/api/generators',
  body('name').trim().notEmpty(),
  body('rif').trim().optional(),
  async (req, res) => {
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      return res.status(400).json({ errors: errors.array() });
    }
    // ... create logic
  }
);

​
7. Secure Database Credentials

Ensure database credentials are stored securely:
  • Use environment variables (.env file)
  • Never commit credentials to version control
  • Use strong passwords
  • Limit database user permissions

​
Environment Variables for Security

Add these to your .env file: 
# API Security
API_KEY=your-secret-api-key-here
JWT_SECRET=your-jwt-secret-here
ALLOWED_ORIGINS=https://yourapp.com,https://admin.yourapp.com

# Database (already configured)
PGHOST=127.0.0.1
PGPORT=5432
PGUSER=postgres
PGPASSWORD=your-secure-password
PGDATABASE=tickets

# Server
PORT=4000
NODE_ENV=production

​
Database Security

The current implementation uses parameterized queries (server/index.js:116-892), which provides protection against SQL injection: 
// Good - uses parameterized queries
const result = await pool.query(
  'SELECT * FROM generators WHERE id = $1',
  [id]
);
Continue using this pattern for all database queries.
