Activities or No Tasks

For a state machine that has only Activity tasks, or no tasks at all, use an IAM policy that denies access to all actions and resources.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Deny",
            "Action": "*",
            "Resource": "*"
        }
    ]
}
