Utvecklarna av Mozilla rapporterade<\/a><\/noindex> om genomf\u00f6randet av en ny studie i samband med f\u00f6rberedelserna f\u00f6r implementeringen av funktionen f\u00f6r DNS-f\u00f6rfr\u00e5gningar \u00f6ver HTTPS (DoH, DNS \u00f6ver HTTPS). Under det genomf\u00f6rda experimentet kommer statistiken \u00f6ver anv\u00e4ndningen av f\u00f6r\u00e4ldrakontrollsystem och f\u00f6retagsl\u00f6sare att samlas in fr\u00e5n systemen hos en del av anv\u00e4ndarna av Firefox-versioner fr\u00e5n USA. Du kan avst\u00e5 fr\u00e5n att delta i experimentet via sidan \u00ababout:studies\u00bb (studien presenteras i listan som \u00abDetection Logic for DNS-over-HTTPS\u00bb).<\/p>\n

F\u00f6r studien kommer anonymiserade uppgifter att samlas in, som endast inkluderar r\u00e4kneverk, utan specifika adresser och dom\u00e4ner. F\u00f6r att identifiera f\u00f6r\u00e4ldrakontrollsystem kommer en f\u00f6rfr\u00e5gan att skickas f\u00f6r att best\u00e4mma namnet exampleadultsite.com och om detta inte \u00f6verensst\u00e4mmer med den faktiska IP-adressen kan det betyda att blockering av vuxeninneh\u00e5ll \u00e4r aktiv p\u00e5 DNS-niv\u00e5. Det kommer ocks\u00e5 att utv\u00e4rderas IP-adresser<\/a> de svar som ges f\u00f6r Google och YouTube, f\u00f6r att kontrollera deras omdirigeringar till restrict.youtube.com, forcesafesearch.google.com och restrictmoderate.youtube.com. <\/p>\n

F\u00f6r att identifiera anv\u00e4ndningen av interna f\u00f6retagsresolvrar kommer de v\u00e4rdar som best\u00e4ms n\u00e4r webbplatser \u00f6ppnas att kontrolleras f\u00f6r anv\u00e4ndning av ovanliga toppdom\u00e4ner (TLD) och f\u00f6r att se om de returnerar intran\u00e4tadresser. Motivet f\u00f6r experimentet \u00e4r oro \u00f6ver att standardaktiveringen av DNS-over-HTTPS kan st\u00f6ra funktionen hos befintliga DNS-baserade f\u00f6r\u00e4ldrakontrollssystem och skapa problem f\u00f6r anv\u00e4ndare av f\u00f6retagsn\u00e4tverk, som anv\u00e4nder DNS-servrar som ger information om interna dom\u00e4ner som inte \u00e4r synliga i det externa n\u00e4tverket.<\/p>\n

Vi p\u00e5minner om att DoH kan vara anv\u00e4ndbart f\u00f6r att f\u00f6rhindra l\u00e4ckor av information om efterfr\u00e5gade v\u00e4rdnamn via n\u00e4tverksleverant\u00f6rens DNS-servrar, bek\u00e4mpa MITM-attacker och manipulering av DNS-trafik, motarbeta DNS-blockeringar eller f\u00f6r att m\u00f6jligg\u00f6ra anslutningar n\u00e4r direkt kontakt med DNS-servrar \u00e4r om\u00f6jlig (till exempel vid anv\u00e4ndning av en proxy). I normala fall skickas DNS-f\u00f6rfr\u00e5gningar direkt till specifika DNS-servrar som anges i systemets konfiguration, men med DoH inkapslas IP-adressf\u00f6rfr\u00e5gan i HTTPS-trafik och skickas till en HTTP-server d\u00e4r en resolver hanterar f\u00f6rfr\u00e5gningar via ett Web API. Den existerande standarden DNSSEC anv\u00e4nder kryptering endast f\u00f6r autentisering av klient och server, men skyddar inte trafiken fr\u00e5n avlyssning och garanterar ingen konfidentialitet f\u00f6r f\u00f6rfr\u00e5gningar. <\/p>\n

F\u00f6r att aktivera DoH i about:config m\u00e5ste du \u00e4ndra v\u00e4rdet p\u00e5 variabeln network.trr.mode, som st\u00f6ds fr\u00e5n och med Firefox 60. V\u00e4rde 0 st\u00e4nger av DoH helt; 1 \u2014 anv\u00e4nder DNS eller DoH, beroende p\u00e5 vad som \u00e4r snabbare; 2 \u2014 anv\u00e4nder DoH som standard, med DNS som en reservl\u00f6sning; 3 \u2014 anv\u00e4nder endast DoH; 4 \u2014 speglingsl\u00e4ge d\u00e4r b\u00e5de DoH och DNS anv\u00e4nds parallellt. Som standard anv\u00e4nds CloudFlares DNS-server, men den kan \u00e4ndras via parameter network.trr.uri, till exempel kan man st\u00e4lla in \u00abhttps:\/\/dns.google.com\/experimental\u00bb eller \u00abhttps:\/\/9.9.9.9\/dns-query\u00bb.<\/p>\n
