Amazon OpenSearch Adds Index-Level Encryption with KMS
🔒 Amazon OpenSearch Service now supports index-level encryption using AWS Key Management Service (KMS) customer managed keys. This allows you to assign different customer managed keys to individual indexes on the same domain, enabling more granular, tenant-specific encryption policies and isolating encrypted data across indexes. The capability builds on existing domain-level encryption and is available at no additional cost for domains running OpenSearch 3.3 or later in select AWS Regions.
