Can I restrict the access of IAM users to specific Amazon EC2 resources?
Most essential Amazon EC2 actions don’t support resource-level permissions or conditions, and isolating IAM users or groups of user’s access to Amazon EC2 resources by any criteria other than AWS Region doesn’t fit most use cases. Instead, consider linking multiple different AWS accounts through AWS Organizations.
