AWS govcloud-us documentation change

Service: govcloud-us · 2025-11-07 · Documentation low

File: govcloud-us/latest/UserGuide/govcloud-sso.md

Summary

Corrected URL patterns, ARN formats, and domain specifications for IAM Identity Center in GovCloud regions. Fixed email address formatting and wildcard domain syntax.

Security assessment

Changes improve documentation accuracy for SSO configuration elements but don't address specific security vulnerabilities. The wildcard syntax fixes (e.g., `\*.sso.amazonaws.com`) help prevent potential misconfigurations but don't represent new security features or address known exploits.
