Managing OS user accounts and groups on managed nodes using Fleet Manager
You can use Fleet Manager, a capability of AWS Systems Manager, to manage operating system (OS) user accounts and groups on your managed nodes. For example, you can create and delete users and groups. Additionally, you can view details like group membership, user roles, and status.
Important
Fleet Manager uses Run Command and Session Manager, capabilities of AWS Systems Manager, for various user management operations. As a result, a user could grant permissions to an operating system user account that they would otherwise be unable to. This is because AWS Systems Manager Agent (SSM Agent) runs on Amazon Elastic Compute Cloud (Amazon EC2) instances using root permissions (Linux) or SYSTEM permissions (Windows Server). For more information about restricting access to root-level commands through SSM Agent, see Restricting access to root-level commands through SSM Agent. To restrict access to this feature, we recommend creating AWS Identity and Access Management (IAM) policies for your users that only allow access to the actions you define. For more information about creating IAM policies for Fleet Manager, see Controlling access to Fleet Manager.
