Security when surfing the web is one of the most Relevant priorities that we must keep in mind when we access regardless of the type of action we take. Through the Internet thousands of attacks of various types are generated that violate our privacy and information if they become effective.

To counter these vulnerabilities a bit, software developers (especially speaking of web browsers), have implemented DNS over HTTPS (DoH) which is a new security and privacy standard to encrypt DNS requests that run within the browser.

DoH has been developed to improve network browsing security. This is because when we enter a website, the browser will send a request through the Internet in order to find the IP address of that particular website. This is normal, which is not very reliable, is that this request is sent to those servers using a plain text connection, that is, this connection is not encrypted.

Such a failure will allow an attacker with the appropriate tools to see what site we are visiting as well as the data we are registering there creating a security hole for the user.

If we decide to enable DNS over HTTPS (DoH), it takes care that the domain name sent to the DNS server, which must be compatible with DoH, makes use of an encrypted HTTPS connection thus replacing the plain text connection. In this way we will be preventing you from seeing the sites we are trying to access.

Since March 2018, both Google and Firefox are running tests of the DNS versions through HTTPS in their browsers to increase end-user security.

DoH makes use of HTTP / 2 and HTTPS and additionally it is compatible with DNS response data. However, some key aspects of the protocol still need to be improved, such as:

  • Parental control and content filters
  • CDN location
  • DNS for companies
  • Interoperability with 5G networks

With DoH we can be sure that our Internet provider (ISP) does not distribute our data to third parties for advertising, policy or any other element that affects privacy.

Now with Solvetic you will see how to activate DNS over HTTPS in Google Chrome, Firefox Quantum or Microsoft Edge.
