Mapping the DNSSEC Quality of DNSSEC-secured .se Domains (English)
Abstract [sv]

Sveriges toppdomän, .se, drivs av Internetstiftelsen som också främjar användningen av DNSSEC, vilket är ett tillägg till protokollet DNS (Domännamnsystemet) som ger ett säkerhetsskydd till DNS-poster. Internetstiftelsen har god kunskap om antalet DNSSEC-säkrade domäner under .se, men ingen kunskap om dessa är uppsatta i enlighet med rekommendationerna för DNSSEC. I detta arbete görs en kartläggning av DNSSEC-kvaliteten hos underdomäner till .se-domänen, som är utpekade som DNSSEC-signerade. Slutsatsen i studien blev att majoriteten av de undersökta domänerna har implementerat DNSSEC i enlighet med DNS-standarder och rekommendationer. Däremot finns ett litet antal domäner som visar brister när det gäller DNSSEC. Denna kartläggning visar alltså att majoriteten av .se-domänerna har en god DNSSEC-kvalitet, men att det finns utrymme för förbättringar för att säkerställa en högre säkerhetsnivå för samtliga domäner. 

Abstract [en]

Sweden's top-level domain, .se, is operated by Internetstiftelsen (The Swedish Internet Foundation), which also promotes the use of DNSSEC, an extension to the DNS (Domain Name System) protocol that provides security protection to DNS records. Internetstiftelsen has good knowledge of the number of DNSSEC-secured domains, but no knowledge of whether they are set up in accordance with DNSSEC recommendations. This study maps the DNSSEC quality of subdomains to the .se domain, which are designated as DNSSEC-signed by the .se domain. The conclusion of the study is that the majority of the examined domains have implemented DNSSEC in accordance with DNS standards and recommendations. However, there are a small number of domains that show deficiencies in DNSSEC. This mapping thus shows that the majority of .se domains have good DNSSEC quality, but that there is room for improvement to ensure a higher level of security for all domains.
