Los desarrolladores de Firefox han anunciado la expansi\u00f3n del uso del modo DNS sobre HTTPS (DoH, DNS over HTTPS), que se habilitar\u00e1 por defecto para los usuarios de Canad\u00e1 (anteriormente, DoH se aplicaba por defecto solo en EE. UU.). La activaci\u00f3n de DoH para los usuarios de Canad\u00e1 se llevar\u00e1 a cabo en varias etapas: el 20 de julio, DoH se activar\u00e1 para el 1% de los usuarios de Canad\u00e1 y, si no surgen problemas imprevistos, la cobertura se incrementar\u00e1 al 100% a finales de septiembre. <\/p>\n

La traducci\u00f3n de los usuarios canadienses de Firefox a DoH se lleva a cabo con la participaci\u00f3n de la organizaci\u00f3n CIRA (Autoridad de Registro de Internet de Canad\u00e1), que regula el desarrollo de Internet en Canad\u00e1 y es responsable del dominio de nivel superior \u00abca\u00bb. La organizaci\u00f3n CIRA tambi\u00e9n se ha unido al programa TRR (Resolutor Recursivo de Confianza) y est\u00e1 incluida entre los proveedores de DNS-over-HTTPS disponibles en Firefox. <\/p>\n

Despu\u00e9s de activar DoH, el sistema del usuario mostrar\u00e1 una advertencia que permitir\u00e1 optar por no cambiar a DoH y continuar utilizando el esquema tradicional de env\u00edo de consultas no cifradas al servidor DNS del proveedor. Se puede cambiar de proveedor o desactivar DoH en la configuraci\u00f3n de la conexi\u00f3n de red. Adem\u00e1s de los servidores DoH de CIRA, se pueden elegir los servicios de Cloudflare y NextDNS.

\"DNS-over-HTTPS<\/center> <\/p>\n

Los proveedores de DoH ofrecidos en Firefox se seleccionan de acuerdo con los requisitos para resolutores DNS dignos de confianza, bajo los cuales el operador de DNS solo puede usar los datos obtenidos para resoluci\u00f3n para operar el servicio, no debe conservar registros durante m\u00e1s de 24 horas, no puede transmitir datos a terceros y debe divulgar informaci\u00f3n sobre los m\u00e9todos de procesamiento de datos. El servicio tambi\u00e9n debe comprometerse a no censurar, filtrar, interferir ni bloquear el tr\u00e1fico DNS, excepto en las situaciones previstas por la ley. <\/p>\n

Recordemos que DoH puede ser \u00fatil para eliminar filtraciones de informaci\u00f3n sobre los nombres de host solicitados a trav\u00e9s de los servidores DNS del proveedor, combatir ataques MITM y sustituciones de tr\u00e1fico DNS (por ejemplo, al conectarse a Wi-Fi p\u00fablico), y resistir bloqueos a nivel de DNS (DoH no puede reemplazar VPN<\/a> en el \u00e1mbito de eludir bloqueos, implementados a nivel de DPI) o para organizar el funcionamiento en caso de imposibilidad de acceso directo a servidores DNS (por ejemplo, al trabajar a trav\u00e9s de un proxy). Si en una situaci\u00f3n normal las consultas DNS se env\u00edan directamente a los servidores DNS especificados en la configuraci\u00f3n del sistema, en el caso de DoH la solicitud para determinar IP<\/a> el host se encapsula en el tr\u00e1fico HTTPS y se env\u00eda a un servidor HTTP, donde el resolver procesa las solicitudes a trav\u00e9s de Web API. El est\u00e1ndar actual DNSSEC utiliza cifrado solo para la autenticaci\u00f3n del cliente y el servidor, pero no protege el tr\u00e1fico de la intercepci\u00f3n ni garantiza la confidencialidad de las solicitudes.
