Implementing fine-grained Amazon Route 53 access using AWS IAM condition keys (Part 1)

This article discusses implementing fine-grained Amazon Route 53 access control using AWS IAM condition keys and principal tags. It provides a detailed approach for managing DNS record permissions in shared hosted zones.

• Solution enables granular control over DNS record management for multiple teams
• Uses IAM condition keys to restrict DNS record updates based on user tags
• Four permission policy approaches are demonstrated:
  • Allow specific DNS record access
  • Deny specific DNS record access
  • Allow DNS records with specific suffix
  • Deny DNS records with specific suffix
• Implementation involves creating principal tags, permission policies, and attaching policies to users or groups
• Provides method to limit DNS record modifications in shared hosted zones

The solution offers a scalable way to implement least-privilege access control for DNS record management across teams and shared environments.
