Implementing Fine-Grained Route 53 Access Using AWS IAM Condition Keys

This article discusses a scalable solution for fine-grained access to Amazon Route 53 hosted zones using AWS Identity and Access Management (IAM) condition keys and principal tags. The solution grants conditional access to update a subset of DNS records in a shared hosted zone. IAM policy condition elements are used to specify the circumstances under which the policy grants or denies permissions, streamlining access management and aligning with least-privilege principles.
