Service: securityhub · 2025-06-13 · Documentation low

File: securityhub/latest/userguide/opensearch-controls.md

Summary

Updated service name to 'Amazon OpenSearch Service', condensed text, and rephrased control rationale for three-node requirement

Security assessment

Changes are primarily branding and clarity improvements. The three-node control relates to availability/reliability rather than direct security vulnerabilities, with no evidence of addressing a specific security flaw.
