Summary

Updated tagging documentation for AWS Transform network migration, changing from optional tagging to mandatory tagging configuration with detailed automatic tags for launch/replication and MAP program tags

Security assessment

The changes enhance documentation about resource tagging which supports security best practices like resource tracking, compliance, and access control. However, there's no evidence of addressing a specific security vulnerability or incident. The changes clarify tagging requirements for network resources during migration, which can help with security posture management but isn't directly fixing a security issue.
