In build notturni<\/a><\/noindex> Firefox predefinito disattivata<\/a><\/noindex> supporto per i protocolli TLS 1.0 e TLS 1.1 (la configurazione security.tls.version.min \u00e8 impostata su 3, il che stabilisce TLS 1.2 come versione minima). Nei rilasci stabili, il supporto per TLS 1.0\/1.1 sar\u00e0 disabilitato a marzo 2020. In Chrome, il supporto per TLS 1.0\/1.1 cesser\u00e0 con Chrome 81, previsto per gennaio 2020. <\/p>\n

La specifica TLS 1.0 \u00e8 stata pubblicata a gennaio 1999. Sette anni dopo \u00e8 stato rilasciato l'aggiornamento TLS 1.1, con miglioramenti alla sicurezza riguardanti la generazione di vettori di inizializzazione e riempimenti. Attualmente, il comitato IETF (Internet Engineering Task Force) che si occupa dello sviluppo dei protocolli e dell'architettura di internet,
\nsviluppa<\/a><\/noindex> una bozza di specifica che classifica i protocolli TLS 1.0\/1.1 come obsoleti. Secondo i dati del servizio SSL Pulse<\/a><\/noindex> Al 3 settembre, il protocollo TLS 1.2 \u00e8 supportato dal 95,8% dei siti web che consentono la creazione di connessioni sicure, mentre il TLS 1.3 \u00e8 al 17,7%. Le connessioni TLS 1.1 sono consentite dal 75,5% dei siti HTTPS, e il TLS 1.0 dal 65,5%.<\/p>\n

I principali problemi di TLS 1.0\/1.1 sono la mancanza di supporto per ciphers moderni (come ECDHE e AEAD) e l'obbligo di supportare vecchi ciphers, la cui affidabilit\u00e0 \u00e8 messa in discussione nello sviluppo attuale della tecnologia informatica (ad esempio, \u00e8 richiesto il supporto per TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA, mentre per la verifica dell'integrit\u00e0 e dell'autenticazione vengono utilizzati MD5 e SHA-1). Il supporto per algoritmi obsoleti ha gi\u00e0 portato all'emergere di attacchi come
\nROBOT<\/a><\/noindex>, DROWN<\/a><\/noindex>, BEAST<\/a><\/noindex>, Logjam<\/a><\/noindex> e FREAK<\/a><\/noindex>. Tuttavia, questi problemi non erano direttamente vulnerabilit\u00e0 del protocollo e venivano risolti a livello delle sue implementazioni. Nei protocolli stessi TLS 1.0\/1.1 non vi sono vulnerabilit\u00e0 critiche che possano essere sfruttate per condurre attacchi pratici.<\/p>\n
