• Progressive Media Quality: Start with 480p@15fps, upgrade to 1080p@30fps after connection
• Optimized ICE Servers: Multiple STUN servers for faster peer discovery
• Pre-gathered ICE Candidates: Pool size of 10 for instant connection
• Bundle Policy: Single connection for all media streams
• Connection Quality Monitoring: Real-time RTT and packet loss tracking

• Rate Limiting: 20 messages/minute per user, 100 API requests/15min per IP
• Message Validation: XSS prevention, 500 character limit, HTML tag filtering
• CORS Protection: Whitelist of allowed origins only
• Security Headers: X-Frame-Options, X-XSS-Protection, Content-Type-Options
• Input Sanitization: All user inputs validated before processing
• Connection Limits: Maximum 3 connections per IP address

• DTLS Encryption: Built-in end-to-end encryption for all media
• SRTP: Secure Real-time Transport Protocol for media streams
• ICE Security: STUN/TURN with authentication
• Media Constraints: Device enumeration with privacy protection

• Message Encryption: All messages encrypted in transit
• Content Filtering: HTML/script tag prevention
• Rate Limiting: Per-user message throttling
• Session Isolation: Messages only between connected peers

• Device Permission: Explicit user consent required
• Camera Selection: Preference for physical over virtual cameras
• Stream Isolation: Each connection gets unique stream
• Quality Adaptation: Automatic quality adjustment based on connection

// Consider implementing:
interface UserSession {
  sessionId: string;
  timestamp: number;
  ipAddress: string;
  userAgent: string;
}

// JWT tokens for session management
// OAuth integration for verified users
// Optional user profiles with moderation

• HTTPS Everywhere: Force SSL/TLS for all connections
• TURN Server: Add authenticated TURN server for NAT traversal
• CDN: Use CDN for static assets and DDoS protection
• WAF: Web Application Firewall for additional protection
• Monitoring: Real-time security monitoring and alerting

• No Data Storage: Zero persistence of video/audio/chat data
• IP Masking: Consider proxy/relay servers
• GDPR Compliance: Privacy policy and data handling
• Age Verification: Consider age restrictions
• Content Moderation: AI-powered content filtering

// Recommended logging structure:
interface SecurityEvent {
  type: 'connection' | 'message' | 'violation' | 'error';
  severity: 'low' | 'medium' | 'high' | 'critical';
  userId: string;
  ipAddress: string;
  timestamp: number;
  details: Record<string, any>;
}

1. No User Authentication: Anonymous connections only
2. Limited Moderation: No content filtering beyond XSS
3. No Reporting System: Basic report modal without backend
4. Single Server: No load balancing or failover
5. No Geographic Restrictions: Worldwide access
