Summary

Updated service principal names from 'osis.amazon.com' to 'osis.amazonaws.com' and 'self-managed-vpce.osis.amazon.com' to 'self-managed-vpce.osis.amazonaws.com' in service-linked role trust policies.

Security assessment

This change corrects the domain names in service principal references for IAM roles. It ensures the trust policies use the correct AWS service domain, which is important for proper IAM role functioning but does not address a security vulnerability. The correction prevents potential misconfiguration that could affect service access.
