How are my persisted long-term AWS security credentials in Automation with AWS secured against unauthorized usage?

Automation with AWS integrates with Identity Federation for AWS to provide shared AWS Security Credentials management – refer to https://utoolity.atlassian.net/wiki/spaces/UAAWS/pages/96895014 for details.

The security aspect is addressed in https://utoolity.atlassian.net/wiki/spaces/UAAKB/pages/1237418018.
