This is how you can improve security when browsing by activating DNS over HTTPS in Edge

A while ago we have seen how the latest Microsoft Build for Windows 10 in the Fast Ring, activated the DNS protocol over HTTPS, also known as DoH. A system to make browsing on our computer more private as well as more secure.

DNS over HTTPS or DoH, the acronym we will use from now on, what it does is make things more difficult for our internet providerwhen it comes to knowing our habits when we surf the net. The clearest example is that it will be more difficult for you to know which pages we visit, but incidentally we also gain security by making attacks from the network a little more difficult.

Advantages of the DoH protocol

Activating DoH in the browser we use is very simple. Just take a few steps to be able to implement this security protocol in browsers that support it. Luckily, the three most used are compatible, so let's see how to activate DoH in Edge, Chrome and Firefox

Once we have activated the use of DNS through HTTPS, what we do is improve the security of our browsing On the one hand we put more difficult to suffer attacks from the network, by encrypting the DNS and preventing them from being based on plain text. In addition, by encrypting these DNS what we do is make it more difficult for our provider to know our browsing habits.

DoH on Edge (the one based on Chromium)

"

We are going to use the well-known menu flags>edge://flags."

"

In the search box that opens at the top, type dns secure>Secure DNS lookups. We only have to mark the option in Enabled, since it is deactivated by default, and then restart the browser."

DoH in Google Chrome

"

In the case of Chrome, the tutorial is almost identical to the previous one, with the only difference of using chrome://flags in instead of edge://flags in the search bar. For the tests, I have used Chrome Canary, since in the stable version of Chrome I still do not see support for DoH."

"

Once inside the flags menu, look for and activate Secure DNS lookups, then restart the browser and apply the changes ."

Doh in Firefox

"

The case of Firefox is different from the two previous ones. Do not use experimental functions and it is based on accessing the menu Preferences of Firefox and within look for the option General In this section we look for Network configuration and we will see a window with different options among which we must look for and activate the option Enable DNS on HTTPS In this case we can choose between two well-known service providers such as Cloudflare and NextDNS.
