Access control with IAM Identity Center session tags

This article explains how to implement fine-grained access control using IAM Identity Center session tags with Microsoft Entra ID federation.

• Combine IAM Identity Center permission sets with session tags for dynamic attribute-based access control
• Session tags pass user attributes from external identity providers into AWS for context-aware permissions
• Configure SAML and SCIM integration between Microsoft Entra ID and IAM Identity Center
• Map Entra ID group membership to session tags using claim conditions
• Use session tags with AWS Glue usage profiles to enforce resource configuration policies
• Validate setup through AWS CloudTrail by inspecting AssumeRoleWithSAML events
• Extensible approach works with other services like AWS Systems Manager Session Manager

This solution enables organizations to manage secure, scalable access across multiple AWS accounts using centralized identity federation without managing individual IAM users.
