Implement fine-grained access control using Amazon OpenSearch Service and JSON Web Tokens

This AWS Big Data Blog article details how to implement fine-grained access control using Amazon OpenSearch Service and JSON Web Tokens (JWTs) for a secure search application. The solution enables role-based data access control for research institutions managing biomedical databases.

• Uses JWTs from identity providers to control document and field-level access
• Implements role-based permissions like PubMed Admin, PubMed Limited, and Clinical Trials roles
• Leverages Amazon Cognito for user authentication and token generation
• Demonstrates document-level and field-level security features
• Allows dynamic filtering of search results based on user roles

The solution provides a standardized approach to authentication and authorization, ensuring users can only access information appropriate to their role while maintaining data privacy and organizational security standards.
