What is DNSSEC

DNSSEC stands for Domain Name System Security Extensions. It is a set of security protocols and mechanisms that are designed to protect the Domain Name System (DNS) from various types of attacks, such as DNS cache poisoning and man-in-the-middle attacks.

DNSSEC works by adding digital signatures to the DNS data, including domain names, IP addresses, and other related information. These signatures are created using public key cryptography, which allows the DNS resolver to verify the authenticity and integrity of the DNS data.

DNSSEC also provides a mechanism for secure delegation of domain names, which allows domain owners to specify which DNS servers are authorized to handle requests for their domain. This helps prevent attacks that attempt to redirect or intercept DNS requests for a domain.

Overall, DNSSEC is an important security enhancement to the DNS infrastructure, helping to ensure that users can trust the accuracy and authenticity of the DNS data they receive, and that the DNS remains a reliable and secure system for the Internet.
