DNSSEC

DNS Security Extensions (DNSSEC) adds cryptographic signatures to DNS records, allowing resolvers to verify that DNS responses have not been tampered with. It protects against DNS cache poisoning and man-in-the-middle attacks that could redirect users to malicious servers. DNSSEC creates a chain of trust from root DNS servers down to individual domain records. Enabling DNSSEC requires configuration at both the registrar and DNS provider level.
