Bei Mozilla haben abgeschlossen<\/a><\/noindex> die Testphase zur Unterst\u00fctzung von DNS \u00fcber HTTPS (DNS over HTTPS, DoH) und planen, die Funktion bis Ende des Monats in den USA einzuf\u00fchren. Nach dem vollst\u00e4ndigen Start wird die M\u00f6glichkeit, das Protokoll auch in anderen L\u00e4ndern zu aktivieren, gepr\u00fcft.<\/p>\n

\"Mozilla<\/p>\n

Diese Technologie erm\u00f6glicht die Verschl\u00fcsselung von DNS-Datenverkehr, wobei die Funktion im Browser deaktiviert werden kann, um herk\u00f6mmliche DNS-Anfragen zu nutzen. Wahrscheinlich werden Nutzer von Kindersicherungssystemen und Unternehmensnetzwerken so verfahren, da diese Systeme Pr\u00fcfungen zur automatischen Deaktivierung von DoH beinhalten.<\/p>\n

Eine solche Technologie kann n\u00fctzlich sein, um Datenlecks \u00fcber die DNS-Server der Anbieter zu verhindern. Sie kann auch gegen MITM-Attacken, DNS-Datenverkehrsmanipulationen und Umgehung von Blockierungen eingesetzt werden, von Domainnamen<\/a> und so weiter. Der aktuelle Standard DNSSEC verwendet lediglich zur Authentifizierung von Client und Server Verschl\u00fcsselung, bietet jedoch keinen Schutz vor Datenabfang oder -manipulation.<\/p>\n

Die Aktivierung von DoH in about:config erfolgt \u00fcber die Variable network.trr.mode, die in Firefox 60 eingef\u00fchrt wurde. Bei dem Wert 0 wird DoH vollst\u00e4ndig deaktiviert. Der Wert 1 erm\u00f6glicht eine automatische Auswahl zwischen DNS oder DoH, je nachdem, was schneller arbeitet. Bei 2 wird DoH standardm\u00e4\u00dfig verwendet, w\u00e4hrend DNS als R\u00fcckfalloption dient. Bei dem Wert 3 wird ausschlie\u00dflich DNS over HTTPS verwendet. Schlie\u00dflich aktiviert der Parameter 4 den Spiegelungsmodus, in dem DoH und DNS parallel funktionieren. Dabei wird der DNS-Server von CloudFlare verwendet, obwohl dieser ge\u00e4ndert werden kann.<\/p>\n
