DNSSEC

What is DNSSEC?

You can see DNSSEC as a patch to otherwise unsafe DNS. It brings cryptography to the table and a whole line of trust, which guarantees every level and provides top-notch security for your domain.

What does DNSSEC mean?

The whole meaning of DNSSEC is a mouth full – Domain Name System Security Extensions.

The original DNS is fast and reliable, but it lacks security. It wasn’t that of a problem when it was first created. Later, in 1993, the Internet Engineering Task Force (IETF) finalized specifications for DNS data encryption standards. It got in use in 2005, and its latest revision is from 2010. 

The DNSSEC aims to stop the DNS cache poisoning and alteration of the DNS data that could happen if it is not activated.

The DNSSEC involves all levels of a domain, including the root, TLD, and the part that you can manage.

It uses a combination of public and private keys, where each upper level can verify the level below.

It is a chain of trust. If one level fails, the chain is broken, and the data cannot be trusted.

DNS records are some of those important components. They are simple and brief messages, instructions for DNS servers to execute specific tasks. The syntax and commands DNS records contain allow servers to know which IP address is associated with a specific domain name, where to direct a query, the way they (servers) should answer a query, the time they should keep it, etc.
