NIST DNS Security Best Practices: Top 5 Takeaways

This article reviews NIST SP 800-81 (March 2026) DNS Security Best Practices and presents five key takeaways: broaden DNS guidance beyond DNSSEC to securing infrastructure and configuration, recognize DNS as critical to cyber resiliency, acknowledge DNS as a major attack surface exploited by threat actor clusters, adopt Protective DNS as an active security control and telemetry source, and deploy encrypted DNS while detecting rogue encrypted resolvers. The piece frames the guidance as timely amid rising regulation and offers Infoblox services (Inspect and Security Workshops) to help organizations assess and operationalize DNS security.
