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.
