# DNSSEC

DNSSEC is the security of a [DNS](https://www.bartvisions.cz/en/slovnikovy-pojem/dns-2/) server with a unique key through what is known as asymmetric encryption. This means that it uses two keys. One for encryption and one for decryption. The first key is used by the [domain](https://www.bartvisions.cz/en/slovnikovy-pojem/domain/) owner to sign and encrypt the data they put on the domain. The others then use the public key to authenticate the data.  
This security prevents attackers from spoofing the [IP address](https://www.bartvisions.cz/en/slovnikovy-pojem/ip-address/) of the domain you want to visit and redirecting it to a spoofed website. You can secure your domain using DNSSEC by contacting your registrar. However, it is important to have your connection secured as well, your internet provider will arrange this for you.
