What is DNSSEC?
Domain Name System Security Extensions or, simply for short, DNSSEC combines several security measures that implement cryptographic authentication of the DNS information. It serves to prove that the DNS data has not been modified, although it still does not encrypt the DNS records. It acts similar to a chain of trust that supports verifying each step that a DNS query makes.
At its origin, the DNS (Domain Name System) is fast and stable. However, it has one great downside, which is exactly lacking security. When we look back in the days at its creation, it was not that big of a deal. But, unfortunately, things have changed, and more protection is highly required.
