Domain Name System Security Extensions
Domain Name System Security Extensions (DNSSEC) is a set of specifications and protocols that add an extra layer of security to the Domain Name System (DNS). DNSSEC aims to prevent data manipulation and provide authentication and integrity to the information exchanged between DNS servers.
About
DNSSEC aims to prevent data manipulation and provide authentication and integrity to the information exchanged between DNS servers. It achieves this by digitally signing the DNS data, creating a chain of trust that can be verified by clients. This verification process ensures that the received data has not been tampered with during transmission. Furthermore, DNSSEC also provides protection against attacks such as cache poisoning and DNS hijacking. The implementation of DNSSEC requires the coordination of various entities, including domain registrars, DNS operators, and software providers. DNSSEC has gradually gained adoption since its introduction in 2005, with many top-level domains and organizations worldwide deploying it to enhance the security of their DNS infrastructure.
