Request Flow:
1. Middleware (security headers, CORS, pattern blocking)
2. Rate Limiting (IP-based throttling)
3. Input Validation (sanitization, size limits)
4. Business Logic (secure processing)
5. Response (security headers, rate limit info)

• Rate limiting: 5 requests per 15 minutes
• Email validation and sanitization
• Payload size validation (5KB limit)
• User agent and referrer sanitization
• Proper error handling without information leakage

• Rate limiting: 20 requests per 15 minutes
• Event data validation
• Payload size validation (5KB limit)
• Data sanitization before storage

• Rate limiting disabled for easier testing
• Relaxed CSP for development tools
• Enhanced logging enabled

• Full security measures enabled
• Strict CSP enforcement
• HTTPS enforcement via HSTS
• Secure cookie flags

1. Defense in Depth: Multiple layers of security
2. Principle of Least Privilege: Minimal permissions and access
3. Input Validation: All user inputs validated and sanitized
4. Secure Defaults: Security-first configuration
5. Error Handling: No sensitive information in error messages
6. Logging: Security events logged (in production)

• Rate limit headers in all API responses
