Amazon OpenSearch Service adds fine-grained access control

AI Impact Summary

Amazon OpenSearch Service has expanded its security capabilities with fine-grained access control, offering granular control over indexes, documents, and fields. This new feature, combined with support for Kibana multi-tenancy and HTTP basic authentication, provides a more secure and flexible environment for managing sensitive data within OpenSearch. The addition of SAML attribute-based access control further enhances security by dynamically mapping users and groups from identity providers to OpenSearch roles, enabling precise permission management.
