What security considerations should be implemented when using WebSockets?
Several security considerations must be implemented when using WebSockets: 1) Use wss:// (WebSocket Secure) protocol to encrypt data transmission, 2) Implement proper authentication and session management, 3) Validate and sanitize all incoming messages to prevent injection attacks, 4) Implement message size limits to prevent DoS attacks, 5) Use origin checking on the server side, 6) Implement proper error handling and connection timeouts, 7) Consider implementing a heartbeat mechanism to detect connection issues.
