Are You Ready for NIST’s New DNS Security Guide? What SP 800-81 Means for Your DNS

NIST has released SP 800-81r3, The Secure Domain Name System (DNS) Deployment Guide, bringing DNS security best practices in line with today’s threat landscape. The guidance highlights DNS as both a high-value attack surface and a powerful enforcement point for enterprise security policy, with a focus on securing DNS infrastructure, ensuring configuration integrity, implementing Protective DNS, and protecting the confidentiality of DNS queries. In this Infoblox webinar, experts will unpack the key changes in SP 800-81r3 and translate them into actionable steps you can take to harden your DNS, reduce risk, and operationalize NIST-aligned DNS security at scale.

Why Attend This Webinar:

  • Understand what’s new in SP 800-81r3
  • Understand how it might relate to NIS2 and other regulations
  • See how to turn DNS from a blind spot into a control point
  • Get practical guidance to reduce DNS-related risk
  • Learn how to implement Encrypted DNS securely
  • Bridge NIST best practices to real-world operations

What NIST SP 800-81r3 Is About:

NIST SP 800-81r3, “Secure Domain Name System (DNS) Deployment Guide,” provides comprehensive recommendations for protecting the integrity, availability, and confidentiality of DNS services across authoritative and recursive infrastructures. It explains how DNS underpins enterprise security posture and zero trust—serving as both a policy enforcement point and a rich source of telemetry for evaluating access and detecting malicious activity. The guide expands beyond DNSSEC to a broader set of best practices: securing DNS infrastructure, ensuring sound configuration and zone management, implementing Protective DNS, minimizing information leakage in queries and responses, and adopting encrypted DNS protocols while detecting and blocking rogue encrypted DNS traffic.
