DNSSEC stands for Domain Name System Security Extension.

The main rule of the DNSSEC protocol is to protect the network against any DNS protocol attack. DNSSEC adds a layer of security to the DNS infrastructure by digitally signing DNS records, ensuring data integrity and authenticity, and protecting against DNS spoofing and cache poisoning attacks.
