Today, we made it easier for you to understand the permissions your AWS Identity and Access Management (IAM) policies grant with policy summaries in the IAM console. Instead of reading JSON policy documents, you can scan a table that summarizes the services, actions, resources, and conditions defined in each policy. This summary enables you to quickly understand the permissions defined in each IAM policy. You can find this summary on the policy detail page or the Permissions tab on an individual IAM user’s page. To learn more about policy summaries, see the blog post, Move Over JSON – Policy Summaries Make Understanding IAM Policies Easier, and the IAM documentation, Understanding Policy Summaries in the AWS Management Console.
