\u00cen construc\u021bii nocturne<\/a><\/noindex> Firefox \u00een mod implicit dezactivat<\/a><\/noindex> suportul pentru protocoalele TLS 1.0 \u0219i TLS 1.1 (setarea security.tls.version.min este configurat\u0103 la 3, stabilind TLS 1.2 ca versiune minim\u0103). \u00cen versiunile stabile, suportul pentru TLS 1.0\/1.1 urma s\u0103 fie dezactivat \u00een martie 2020. \u00cen Chrome, suportul pentru TLS 1.0\/1.1 va fi oprit \u00een Chrome 81, a\u0219teptat \u00een ianuarie 2020. <\/p>\n

Specifica\u021bia TLS 1.0 a fost publicat\u0103 \u00een ianuarie 1999. Dup\u0103 \u0219apte ani, a fost lansat\u0103 actualizarea TLS 1.1 cu \u00eembun\u0103t\u0103\u021biri de securitate legate de generarea vectorilor de ini\u021bializare \u0219i a umpluturii. \u00cen prezent, comitetul IETF (Internet Engineering Task Force), care se ocup\u0103 de dezvoltarea protocoalelor \u0219i arhitecturii internetului,
\ndezvolt\u0103<\/a><\/noindex> a redactat o specifica\u021bie care trece protocoalele TLS 1.0\/1.1 \u00eentr-o categorie de dep\u0103\u0219ire. Conform unui serviciu SSL Pulse<\/a><\/noindex> la data de 3 septembrie, protocolul TLS 1.2 este suportat de 95,8% dintre site-urile web care permit conectarea prin conexiuni securizate, \u00een timp ce TLS 1.3 este suportat de 17,7%. Conexiunile prin TLS 1.1 sunt acceptate de 75,5% dintre site-urile HTTPS, iar TLS 1.0 de 65,5%.<\/p>\n

Principalele probleme ale TLS 1.0\/1.1 sunt lipsa suportului pentru cript\u0103ri moderne (de exemplu, ECDHE \u0219i AEAD) \u0219i cerin\u021ba de suport pentru cript\u0103ri vechi, a c\u0103ror fiabilitate \u00een stadiul actual al dezvolt\u0103rii tehnicii de calcul este pus\u0103 la \u00eendoial\u0103 (de exemplu, este necesar suportul pentru TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA, iar pentru verificarea integrit\u0103\u021bii \u0219i autentific\u0103rii se folose\u0219te MD5 \u0219i SHA-1). Suportul pentru algoritmi dep\u0103\u0219i\u021bi a dus deja la apari\u021bia unor atacuri cum ar fi
\nROBOT<\/a><\/noindex>, DROWN<\/a><\/noindex>, BEAST<\/a><\/noindex>, Logjam<\/a><\/noindex> \u0219i FREAK<\/a><\/noindex>. Cu toate acestea, aceste probleme nu erau vulnerabilit\u0103\u021bi directe ale protocoalelor \u0219i erau gestionate la nivelul implement\u0103rilor lor. Protocoalele TLS 1.0\/1.1 nu con\u021bin vulnerabilit\u0103\u021bi critice care pot fi exploatate pentru a efectua atacuri practice.<\/p>\n
