AWS AmazonRDS medium security documentation change

Service: AmazonRDS · 2026-02-25 · Security-related medium

File: AmazonRDS/latest/UserGuide/SQLServer.Procedural.Importing.Native.Using.md

Summary

Expanded native backup/restore parameters to support directory buckets, added encryption behavior clarification, usage examples, and ARN formatting requirements.

Security assessment

Documents mandatory encryption enforcement for directory buckets ('@enable_bucket_default_encryption' is always on), which is a security feature. Also adds security-relevant ARN formatting requirements to prevent operational failures.
