This article explains how to implement fine-grained IAM permissions for Amazon Route 53 Profiles to enforce least-privilege access across multi-account DNS management.

• New IAM condition keys enable scoping permissions by resource type, ARN, domain name, and VPC ID
• Application teams can associate only private hosted zones with shared Profiles
• Security teams can manage only DNS Firewall rule groups and their priorities
• Shared services teams can associate and disassociate specific VPCs only
• Condition keys apply to specific API actions; review documentation for supported combinations
• AWS RAM and IAM policies work together; both must permit operations to succeed
• Available in all Route 53 Profiles regions except Middle East (UAE) and Bahrain
• Use IAM Access Analyzer and Policy Simulator to validate policies before production deployment

Fine-grained IAM permissions for Route 53 Profiles enable organizations to delegate DNS operations securely to appropriate teams while maintaining centralized control and governance.
