El Comit\u00e9 IETF (Internet Engineering Task Force), encargado del desarrollo de protocolos y arquitectura de Internet, ha publicado el RFC 8996, que clasifica oficialmente los protocolos TLS 1.0 y 1.1 como tecnolog\u00edas obsoletas. <\/p>\n

La especificaci\u00f3n TLS 1.0 fue publicada en enero de 1999. Siete a\u00f1os despu\u00e9s, se lanz\u00f3 una actualizaci\u00f3n, TLS 1.1, que inclu\u00eda mejoras de seguridad relacionadas con la generaci\u00f3n de vectores de inicializaci\u00f3n y relleno. Seg\u00fan el servicio SSL<\/a> A 16 de enero, el 95.2% de los sitios web que permiten conexiones seguras soportan el protocolo TLS 1.2, mientras que el TLS 1.3 alcanza un 14.2%. Las conexiones mediante TLS 1.1 son utilizadas por el 77.4% de los sitios HTTPS, y el TLS 1.0 por el 68%. Aproximadamente el 21% de los primeros 100,000 sitios en el ranking de Alexa todav\u00eda no utilizan HTTPS. <\/p>\n

Los principales problemas de TLS 1.0\/1.1 son la falta de soporte para cifrados modernos (como ECDHE y AEAD) y la inclusi\u00f3n en la especificaci\u00f3n de requisitos para mantener cifrados antiguos cuya fiabilidad se ha puesto en duda en la actualidad (por ejemplo, se requiere soporte para TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA, y para verificaci\u00f3n de integridad y autenticaci\u00f3n se utilizan MD5 y SHA-1). El soporte para algoritmos obsoletos ya ha llevado a ataques como ROBOT, DROWN, BEAST, Logjam y FREAK. Sin embargo, estos problemas no eran en s\u00ed vulnerabilidades del protocolo y se abordaban a nivel de sus implementaciones. No hay vulnerabilidades cr\u00edticas en los propios protocolos TLS 1.0\/1.1 que puedan ser explotadas en ataques pr\u00e1cticos.
