How does secure DNS work?

228 viewsOtherTechnology

I work in cyber security so I’m already embarrassed to not know this. But I do know how DNS works. I just don’t understand what people mean when they say “secure DNS”. Ive tried looking it up, but it keeps falling flat on me.

I use nextdns on my computer and phone, but I still don’t know what it’s doing, how it works, or anything. Can you explain what makes services like nextDNS secure, or why people change or even have different DNS servers configured?

Basically regular DNS uses postcards without envelopes. Anyone processing the postcard can look at it and read the message (dns query). Secure DNS is like sending a postcard inside an envelope. The post office can process it but the people handling it can’t read the contents. This is oversimplifying it but hey, I’m pretending you’re five years old.
