Entreprise Mozilla a conclu<\/a><\/noindex> accord avec un troisi\u00e8me fournisseur DNS sur HTTPS (DoH, DNS over HTTPS) pour Firefox. En plus des serveurs DNS CloudFlare propos\u00e9s pr\u00e9c\u00e9demment («https:\/\/1.1.1.1\/dns-query») et NextDNS,<\/a><\/noindex> (https:\/\/dns.nextdns.io\/id<\/a><\/noindex>), les param\u00e8tres incluront \u00e9galement le service Comcast (https:\/\/doh.xfinity.com\/dns-query). Activer DoH et choisir un fournisseur<\/a><\/noindex> est possible<\/a><\/noindex> dans les param\u00e8tres de connexion r\u00e9seau. <\/p>\n

Rappelons qu'une v\u00e9rification exp\u00e9rimentale de DNS over HTTPS a \u00e9t\u00e9 activ\u00e9e dans Firefox 77, avec l'envoi de 10 requ\u00eates d'essai par client et la s\u00e9lection automatique du fournisseur DoH. Cette v\u00e9rification a d\u00fb \u00eatre d\u00e9sactiv\u00e9e dans la version 77.0.1<\/a><\/noindex>, car elle s'est transform\u00e9e en une sorte d'attaque DDoS sur le service NextDNS, qui n'a pas pu supporter la charge. <\/p>\n

Les fournisseurs DoH propos\u00e9s dans Firefox sont s\u00e9lectionn\u00e9s en fonction des exigences<\/a><\/noindex> pour les r\u00e9solveurs DNS dignes de confiance, selon lesquelles l'op\u00e9rateur DNS ne peut utiliser les donn\u00e9es obtenues pour le r\u00e9solve peut que pour garantir le bon fonctionnement du service, ne doit pas conserver de journaux pendant plus de 24 heures, ne peut transmettre les donn\u00e9es \u00e0 des tiers et doit divulguer des informations sur les m\u00e9thodes de traitement des donn\u00e9es. Le service doit \u00e9galement s'engager \u00e0 ne pas censurer, filtrer, interf\u00e9rer ou bloquer le trafic DNS, sauf dans les situations pr\u00e9vues par la loi. <\/p>\n

Parmi les \u00e9v\u00e9nements li\u00e9s au DNS-over-HTTPS, on peut \u00e9galement noter que la solution<\/a><\/noindex> la soci\u00e9t\u00e9 Apple mettra en \u0153uvre le support de DNS-over-HTTPS et de DNS-over-TLS dans les futures versions d'iOS 14 et de macOS 11, ainsi que ajouter<\/a><\/noindex> le support des extensions au format WebExtension dans Safari. <\/p>\n

Rappelons que le DoH peut s'av\u00e9rer utile pour \u00e9viter les fuites d'informations sur les noms d'h\u00f4tes demand\u00e9s via les serveurs DNS des fournisseurs, pour lutter contre les attaques MITM et le traffic DNS spoofing (par exemple, lors de la connexion \u00e0 des Wi-Fi publics), pour contrer les blocages au niveau de DNS (le DoH ne peut pas remplacer un VPN en mati\u00e8re de contournement des blocages mis en place au niveau du DPI) ou pour organiser le fonctionnement en cas d'impossibilit\u00e9 d'un acc\u00e8s direct aux serveurs DNS (par exemple, lorsqu'on passe par un proxy). Dans une situation normale, les requ\u00eates DNS sont directement envoy\u00e9es aux serveurs DNS sp\u00e9cifi\u00e9s dans la configuration du syst\u00e8me, alors qu'avec le DoH, la requ\u00eate pour d\u00e9terminer l'adresse IP de l'h\u00f4te est encapsul\u00e9e dans le trafic HTTPS et envoy\u00e9e \u00e0 un serveur HTTP, o\u00f9 le r\u00e9solveur traite les requ\u00eates via une API Web. La norme existante DNSSEC utilise le cryptage uniquement pour authentifier le client et le serveur, mais ne prot\u00e8ge pas le trafic contre l'interception et ne garantit pas la confidentialit\u00e9 des requ\u00eates. <\/p>\n
