Dutch National Cyber Security Centre explains how DNS-monitoring will get more difficult as modern encrypted DNS transport protocols are getting more popular in a fact sheet published this week. The fact sheet’s audience is represented by system or network admins and security officers who want to move to DNS over TLS (DoT) and DNS over HTTPS (DoH) DNS encryptions protocols that offer increased security and confidentiality. Google and Mozilla are both running DoH trials for their browsers, with Chrome to upgrade to a provider’s DoH server if it present on a pre-defined whitelist or to a shortlist of fallback providers.
