A empresa Mozilla concluiu<\/a><\/noindex> acordo com o terceiro provedor de DNS sobre HTTPS (DoH, DNS over HTTPS) para o Firefox. Al\u00e9m dos servidores DNS da CloudFlare anteriormente sugeridos («https:\/\/1.1.1.1\/dns-query») e NextDNS<\/a><\/noindex> (https:\/\/dns.nextdns.io\/id<\/a><\/noindex>), a configura\u00e7\u00e3o tamb\u00e9m incluir\u00e1 o servi\u00e7o Comcast (https:\/\/doh.xfinity.com\/dns-query). Ative o DoH e selecione provedor<\/a><\/noindex> \u00e9 poss\u00edvel<\/a><\/noindex> nas configura\u00e7\u00f5es da conex\u00e3o de rede. <\/p>\n

Lembre-se de que no Firefox 77 foi inclu\u00eddo um teste da verifica\u00e7\u00e3o de DNS over HTTPS, enviando 10 pedidos de teste de cada cliente e selecionando automaticamente o provedor de DoH. Este teste teve que ser desativado na vers\u00e3o 77.0.1<\/a><\/noindex>, pois se transformou em um tipo de ataque DDoS ao servi\u00e7o NextDNS, que n\u00e3o suportou a carga. <\/p>\n

Os provedores de DoH sugeridos no Firefox s\u00e3o selecionados de acordo com os requisitos<\/a><\/noindex> para resolvers DNS confi\u00e1veis, segundo os quais o operador de DNS pode utilizar os dados recebidos para resolu\u00e7\u00e3o apenas para garantir o funcionamento do servi\u00e7o, n\u00e3o deve armazenar logs por mais de 24 horas, n\u00e3o pode compartilhar dados com terceiros e deve divulgar informa\u00e7\u00f5es sobre os m\u00e9todos de tratamento de dados. O servi\u00e7o tamb\u00e9m deve se comprometer a n\u00e3o censurar, filtrar, interferir ou bloquear o tr\u00e1fego DNS, exceto nas situa\u00e7\u00f5es previstas pela legisla\u00e7\u00e3o. <\/p>\n

Nos eventos relacionados ao DNS-over-HTTPS, tamb\u00e9m se pode destacar uma solu\u00e7\u00e3o<\/a><\/noindex> que a Apple implementou suporte para DNS-over-HTTPS e DNS-over-TLS nas futuras vers\u00f5es do iOS 14 e macOS 11, al\u00e9m de adicionar<\/a><\/noindex> suporte para extens\u00f5es no formato WebExtension no Safari. <\/p>\n

Lembre-se de que o DoH pode ser \u00fatil para eliminar vazamentos de informa\u00e7\u00f5es sobre os nomes de host solicitados atrav\u00e9s dos servidores DNS dos provedores, combater ataques MITM e a substitui\u00e7\u00e3o do tr\u00e1fego DNS (por exemplo, ao se conectar a Wi-Fi p\u00fablico), enfrentar bloqueios em n\u00edvel DNS (o DoH n\u00e3o pode substituir uma VPN na \u00e1rea de contornar bloqueios implementados em n\u00edvel DPI) ou para organizar o trabalho em caso de impossibilidade de acesso direto aos servidores DNS (por exemplo, ao trabalhar atrav\u00e9s de um proxy). Se em uma situa\u00e7\u00e3o normal as consultas DNS s\u00e3o enviadas diretamente para determinados servidores DNS configurados no sistema, no caso do DoH, a solicita\u00e7\u00e3o para determinar o endere\u00e7o IP do host \u00e9 encapsulada no tr\u00e1fego HTTPS e enviada para um servidor HTTP, onde o resolvedor processa as solicita\u00e7\u00f5es atrav\u00e9s da API Web. O padr\u00e3o DNSSEC existente usa criptografia apenas para autenticar o cliente e o servidor, mas n\u00e3o protege o tr\u00e1fego contra intercepta\u00e7\u00e3o e n\u00e3o garante a confidencialidade das solicita\u00e7\u00f5es. <\/p>\n
