Layer 3-4 Protection

// SYN Flood Protection
SYN_COOKIE_VALIDATION:
  - Enable SYN cookies for TCP handshake
  - Validate client legitimacy before connection
  - Track connection state in stateless manner

// UDP Flood Mitigation
RATE_LIMITING:
  - Per-source IP rate limiting
  - Per-destination port limiting
  - Geographic-based filtering
  - Dynamic threshold adjustment

Layer 7 Protection

// HTTP Flood Protection
CHALLENGE_RESPONSE:
  - JavaScript challenge for bot detection
  - CAPTCHA for suspicious requests
  - Cookie validation for session tracking
  - User-Agent fingerprinting

// Slowloris Protection
CONNECTION_TIMEOUT:
  - Aggressive timeout for slow connections
  - Maximum concurrent connections per IP
  - Request completion time limits
  - HTTP header size restrictions
