AWS Identity and Access Management (IAM) policy summaries make it easier to view and understand the permissions in your policies when using the IAM console. Today, we updated policy summaries to help you identify and correct errors in your IAM policies. When you set permissions using policies, for each action you specify, you must match that action to supported resources or conditions. Now, you will see a warning if these policy elements (actions, resources, and conditions) defined in an IAM policy do not match. With this update, policy summaries make it easy to detect if a policy includes an action that does not support the resource or condition specified.
