Avoid The Threats

We all appreciate our privacy. We as humans need to be able to do things with the comfort that eyes won’t be watching us. This is the same for our busienss. Governments and corporations can easily use the information they hold to learn about individuals internet behavior and use it against them. They can it to profile the uses for political purposes. They can also target them with ads.

 

Thankfully, there are barriers that exist, such as the efforts of the DNS Privacy Project. This is used to raise awareness of the issue and give advice and resources to help control these threats.

 

There is also the IETF. They have been working on the issues too. This birthed the existence of the DNS PRIVate Exchange, also called DPRIVE. This is a working group used to look into the problems, define them, and evaluate possible courses of actions to mitigate the security threats. One of its major efforts has been to create methods whereby DNS can be used over HTTP (DOH).  Even though DNS queries could take place over HTTP in the clear, that wouldn’t solve the unencrypted privacy issue. Therefore, the protocol development has been on DNS Queries over HTTPS , which was standardized in October 2018. Count on our risk management analysis.

 

DNS Server vs HTTPS

DOH uses a direct connection between the web server and the end-user. Because the DNS response and query are taking place over an HTTP interface, the DNS response uses JSON notation. Besides the typical DNS query, this way is different because it lends itself to more straightforward integration with web-based applications.

 

DOH can be implemented as a local proxy service. This means the local proxy service that is running on the end user’s computer that listens for DNS queries, uses TCP or UDP port 53. The local proxy service will convert the DNS queries into a HTTPS connection to the DOH service. When there is a case om the DNS over HTTPS, the connection is made by using TCP port 443.

 

DOH can also be implemented in the user’s web browser.  When the browser makes a connection to a new URL, it connects to the pre-configured DOH service using TCP 853 and retrieves the JSON response containing the resulting IP address.
