Using managed policies to define access permissions for your IAM users provides various benefits, including the ability to reuse policies, version and rollback policies, automatic updates, larger policy sizes, and granular control over policy assignments. To improve the management and control of access permissions to your AWS account, it is recommended to ensure that all IAM users are using managed policies, both AWS-managed and customer-managed, instead of inline policies (embedded policies). This can help you to more efficiently manage and control access permissions for your users while taking advantage of the benefits offered by managed policies.


To ensure that IAM users are not using inline policies and instead are using managed policies, you can take the following remediation steps:

  1. Identify all IAM users in your AWS account that are using inline policies.
  2. Create new managed policies or select existing ones that meet your requirements.
  3. Attach the managed policies to the appropriate IAM users or groups.
  4. Remove any inline policies that are no longer needed.
  5. Monitor the IAM users to ensure they are using the appropriate policies and access permissions.

By following these remediation steps, you can ensure that IAM users are using managed policies instead of inline policies, which can provide better control and management over access permissions to your AWS resources.
