AWS controltower documentation change

Service: controltower · 2025-11-19 · Documentation low

File: controltower/latest/controlreference/ecr-rules.md

Summary

Updated documentation to remove 'AWS' prefix from CloudFormation references in multiple sections

Security assessment

The changes are purely branding/terminology updates (AWS CloudFormation → CloudFormation) with no modifications to security controls or vulnerability disclosures. The ECR security controls themselves (lifecycle policies, image scanning, immutable tags) remain unchanged in their security implications.
