1. Keep Dependencies Updated: Run npm audit regularly
2. Use HTTPS: Always use HTTPS in production
3. Secure MongoDB: Enable authentication and use strong passwords
4. Environment Variables: Never commit .env files
5. Rate Limiting: Configure appropriate rate limits
6. Origin Whitelist: Only allow trusted domains in ALLOWED_ORIGINS

1. Input Validation: Always validate and sanitize user input
2. Authentication: Use nonce-based authentication for sensitive operations
3. Logging: Never log sensitive data (passwords, tokens, etc.)
4. Error Messages: Don't expose internal details in error messages
5. Dependencies: Only add necessary dependencies and keep them updated

The system requires authentication tokens for payment providers. These must be:

• Stored securely in environment variables
• Rotated regularly
• Never committed to version control
• Transmitted only over HTTPS

• Enable MongoDB authentication
• Use strong passwords
• Restrict network access
• Enable encryption at rest
• Use TLS/SSL for connections

• Sessions expire after 10 minutes
• Nonces are single-use only
• IP address and user agent tracking
• Automatic cleanup of expired sessions

This system handles financial transactions and must comply with:

• PCI DSS: If storing card data (not applicable for UPI-only)
• Data Protection Laws: GDPR, local data protection regulations
• Financial Regulations: RBI guidelines for payment systems (India)

• HTTPS enabled with valid certificate
• MongoDB authentication enabled
• Strong passwords for all services
• Environment variables properly configured
• CORS restricted to production domains
• Rate limiting configured
• Logging enabled and monitored
• Regular backups configured
• Firewall rules in place
• Dependencies updated
• Security headers configured (Helmet.js)
• Input validation on all endpoints
• Error handling doesn't expose internals

We regularly audit our dependencies for security vulnerabilities:

npm audit

Critical and high-severity vulnerabilities are addressed immediately.
