DNSSEC (Domain Name System Security Extensions)is a security protocol that adds cryptographic validation to DNS responses, making it nearly impossible for attackers to spoof DNS responses or redirect users to malicious sites.

NIST SP 800-81 Rev. 2 (Secure Domain Name System (DNS) Deployment Guide):

“DNSSEC provides data origin authentication and data integrity to DNS responses using digital signatures, effectively mitigating spoofing and cache poisoning attacks.”

While patching and awareness are important, DNSSECdirectly mitigatesthe technical risk described.
