What is DNSSEC?

Domain Name System Security Extensions (DNSSEC) is a set of security extensions for the Domain Name System (DNS), a core component of the internet that translates human-readable domain names (e.g., www.example.com) into numerical IP addresses that computers can use to communicate with each other.

DNSSEC is designed to protect against certain types of cyber attacks that can exploit vulnerabilities in DNS to redirect internet users to malicious websites, steal sensitive information, or disrupt service. It adds a layer of authentication to DNS, using digital signatures and public-key encryption to ensure that DNS responses have not been tampered with or forged.

DNSSEC is an important tool for improving the security and integrity of the internet and is widely used by organizations worldwide to protect their domains and their users.
