Briefing for: Security & Risk
What happened
AWS OpenSearch Service now supports cross-account data access, enabling security teams to query and build dashboards from OpenSearch domains hosted in different AWS accounts within a single OpenSearch UI. This feature works across accounts in the same region, for both public and VPC configurations, without requiring data replication or endpoint switching.
Why it matters
This update simplifies the creation of centralized security analytics workflows, providing a unified view of logs and events across your multi-account AWS environment. It helps maintain data locality and existing account-level access controls, which is crucial for compliance and data governance. Security teams can now more efficiently identify threats and anomalies across their infrastructure.
What this enables
- If you manage security logs and events across multiple AWS accounts, you can now centralize your security analytics dashboards without consolidating data.
- If you need to ensure strict access controls for security data, you can leverage existing IAM and IAM Identity Center policies for cross-account OpenSearch access.
- If you are building a multi-account SIEM or observability solution, you can streamline data access and reduce operational overhead.
