AWS managed policies for Amazon EFS

An AWS managed policy is a standalone policy that is created and administered by AWS. AWS managed policies are designed to provide permissions for many common use cases so that you can start assigning permissions to users, groups, and roles.

Keep in mind that AWS managed policies might not grant least-privilege permissions for your specific use cases because they're available for all AWS customers to use. We recommend that you reduce permissions further by defining customer managed policies that are specific to your use cases.

You cannot change the permissions defined in AWS managed policies. If AWS updates the permissions defined in an AWS managed policy, the update affects all principal identities (users, groups, and roles) that the policy is attached to. AWS is most likely to update an AWS managed policy when a new AWS service is launched or new API operations become available for existing services.

For more information, see AWS managed policies in the IAM User Guide.

AWS managed policy: AWSServiceRoleForAmazonElasticFileSystem

Amazon EFS uses the service-linked role named AWSServiceRoleForAmazonElasticFileSystem to allow Amazon EFS to manage AWS resources on your behalf. This role trusts the elasticfilesystem.amazonaws.com service to assume the role. For more information, see Using service-linked roles for Amazon EFS.

AWS managed policy: AmazonElasticFileSystemFullAccess

You can attach the AmazonElasticFileSystemFullAccess policy to your IAM identities.

This policy grants administrative permissions that allow full access to Amazon EFS and access to related AWS services via the AWS Management Console.
