Attach a policy to an IAM user group
You can attach an AWS managed policy—that is, a prewritten policy provided by AWS—to a user group, as explained in the following steps. To attach a customer managed policy—that is, a policy with custom permissions that you create—you must first create the policy. For information about creating customer managed policies, see Define custom IAM permissions with customer managed policies.
For more information about permissions and policies, see Access management for AWS resources.
