Security Expert Comments On Microsoft Will Integrate DNS Over HTTPS In Windows 10

Data Privacy

Microsoft revealed plans to integrate native support for DNS over HTTPS in the company’s Windows 10 operating system in November 2019.

The announcement was made on Microsoft’s Networking blog on November 17, 2019. DNS over HTTPS is designed to improve privacy, security, and reliability by encrypting DNS queries that are handled in plaintext currently.

DNS over HTTPS has been on the rise lately. Mozilla, Google, Opera as well as several public DNS providers announced support for the standard. Support in programs, e.g. a web browser, means that the DNS queries that originate from that program are encrypted. Other queries, e.g. from another browser that does not support DNS over HTTPS or is configured not to use it, won’t benefit from that integration.

I don\’t know of any network administrators who prefer DNS over HTTPS (DoH) to DNS over TLS (DoT). I don\’t understand why Microsoft decided to overload yet another protocol over port 443 TCP when an alternative using port 853 TCP is available and solves all the requirements for security and privacy claimed by DoH advocates.
