Data in transit can be protected through secure network connections using Transport Layer Security (TLS) protocols. These encryption mechanisms ensure that data remains secure both while it is being stored and when it is being transmitted between nodes within the search cluster.
Moreover, Amazon OpenSearch offers fine-grained access control mechanisms to manage user permissions and enforce data access policies. Organizations can define roles and assign specific privileges to users or user groups, controlling their access to different data resources and functionalities within the search engine. This enables organizations to implement the principle of least privilege, granting users only the necessary access rights to perform their tasks.
In addition, Amazon OpenSearch integrates with AWS Identity and Access Management (IAM), allowing organizations to leverage their existing IAM infrastructure to manage access to OpenSearch resources. IAM provides a centralized and unified way to manage user identities, roles, and permissions across various AWS services, including OpenSearch. This simplifies the process of granting and revoking access to OpenSearch resources, ensuring secure and efficient user management.
Multi-Tenancy and Data Isolation
Amazon OpenSearch supports multi-tenancy, allowing organizations to create separate indexes and search domains for different applications or user groups within a shared infrastructure. This multi-tenancy capability provides data isolation and resource segregation, ensuring that each tenant’s data is separate and protected. It allows organizations to efficiently manage diverse datasets and applications within a single OpenSearch environment while maintaining strict data boundaries.
By leveraging multi-tenancy, organizations can achieve cost savings and resource optimization by sharing a common infrastructure for multiple applications. Each tenant can have its own index and search domain, allowing them to independently manage and query their data without interference from other tenants. This ensures that data privacy and security are maintained, as tenants have full control over their data and can enforce their own access policies and permissions.
In addition, Amazon OpenSearch provides features for data partitioning and routing, allowing organizations to optimize the distribution and placement of data across different nodes within the search cluster. This ensures efficient data retrieval and query performance, especially in scenarios where data is distributed across multiple regions or availability zones.
