AWS AWSCloudFormation documentation change

Service: AWSCloudFormation · 2025-09-19 · Documentation medium

File: AWSCloudFormation/latest/TemplateReference/doc-history.md

Summary

Added documentation for updated EVS Environment HCX properties, Bedrock Guardrail integration, and new SMS/VOICE resources including security-related features

Security assessment

Added security controls including HCX network ACL configuration, automated reasoning policies for Guardrails, and SMS/VOICE security features (OptOutList, ProtectConfiguration, ResourcePolicy). While these are security enhancements, there's no evidence they address existing vulnerabilities.
