Stax-managed AWS Accounts can now opt-in to advanced hardening options to block SSM Document public sharing
Further configuration options have been added to the AWS Accounts configurable service page to allow you to fine-tune security protections for all Stax-managed AWS Accounts.
A new toggle to block SSM Document public sharing has been added.
This can be further enforced by appling the Guardrail Block changes to AWS Systems Manager public sharing settings.
For more information, refer to the documentation on Configure AWS Accounts.
