WebSocket consente di inviare solo richieste HTTP, ma una richiesta simile a una porta di rete non attiva termina immediatamente con un errore, mentre per una porta attiva impiega del tempo, necessario per tentare di stabilire una connessione. Inoltre, nel caso di una porta non attiva, WebSocket restituisce il codice di errore di connessione (ERR_CONNECTION_REFUSED), mentre per una porta attiva \u2014 il codice di errore di negoziazione della connessione. <\/p>\n<p><center><noindex><a rel=\"nofollow\" href=\"https:\/\/nullsweep.com\/content\/images\/2020\/05\/ebay_port_scan-1.png\"><img decoding=\"async\" alt=\"uBlock Origin ha aggiunto il blocco degli script per la scansione delle porte di rete.\" src=\"\/wp-content\/uploads\/2020\/06\/a9250f9331486b7871c7446eb59010a8.png\" style=\"display:block;margin: 0 auto;\" \/><\/a><\/noindex><\/center><\/p>\n<p>Oltre alla scansione delle porte, i WebSocket possono anche <noindex><a rel=\"nofollow\" href=\"https:\/\/medium.com\/@stestagg\/stealing-secrets-from-developers-using-websockets-254f98d577a0\">essere utilizzato<\/a><\/noindex> essere utilizzati per attacchi ai sistemi degli sviluppatori web che eseguono handler WebSocket sul sistema locale per applicazioni React.
