NIST Just Connected DNS Security to Its Most Widely Adopted Framework, NIST CSF v2.0

The NIST OLIR mapping formally links SP 800-81r3 (Secure DNS Deployment Guide) to the Cybersecurity Framework (CSF) 2.0, showing how DNS security controls map to CSF subcategories across Identify, Protect, Detect, Respond, and Recover; the mapping gives CISOs, auditors, and procurement teams auditable, standards-based guidance to integrate DNS security into risk assessments, compliance reporting, and procurement requirements, and recommends that organizations review the mapping, assess DNS posture against SP 800-81r3, and integrate DNS controls into CSF 2.0 reporting.
