To enhance security by ensuring that domain name resolutions are authenticated and verifiable, which technology should be implemented?
DNS over TLS (DoT)
DNS over HTTPS (DoH)
SSL
DNSSEC
DNSSEC (Domain Name Security Extensions) enhances the security of the domain name system by signing records with public key cryptography. This allows client systems to verify the authenticity and integrity of the response, protecting against certain types of attacks such as cache poisoning. Technologies like DoH and DoT, while providing confidentiality through encryption of requests, do not offer mechanisms for response validation akin to DNSSEC.
