Domain Name System Security Extensions (DNSSEC) is a suite of extensions to the Domain Name System (DNS) that provides an added layer of security by enabling DNS responses to be verified for authenticity. This helps to protect against various attacks that can manipulate DNS information, such as cache poisoning, where an attacker inserts false data into a DNS resolver's cache.
