AWS prescriptive-guidance documentation change

Service: prescriptive-guidance · 2026-07-10 · Documentation low

File: prescriptive-guidance/latest/rehost-servers-over-private-networks-mgn/deployment.md

Summary

Updated documentation links, terminology (e.g., 'SSM Session Manager' to 'AWS Systems Manager Session Manager'), and automation references. Added explicit script links for Cloud Migration Factory and modified network requirement descriptions.

Security assessment

Changes focus on documentation accuracy, terminology alignment, and automation process improvements. While some network security controls (VPC endpoints, IAM profiles) are mentioned, there's no evidence of addressing a specific vulnerability or new security feature introduction.
