## Actions defined by Amazon Elastic File System

You can specify the following actions in the `Action` element of an IAM policy statement. Use policies to grant permissions to perform an operation in AWS. When you use an action in a policy, you usually allow or deny access to the API operation or CLI command with the same name. However, in some cases, a single action controls access to more than one operation. Alternatively, some operations require several different actions.

The Resource types column indicates whether each action supports resource-level permissions. If there is no value for this column, you must specify all resources ("*") in the `Resource` element of your policy statement. If the column includes a resource type, then you can specify an ARN of that type in a statement with that action. Required resources are indicated in the table with an asterisk (*). If you specify a resource-level permission ARN in a statement using this action, then it must be of this type. Some actions support multiple resource types. If the resource type is optional (not indicated as required), then you can choose to use one but not the other.

For details about the columns in the following table, see The actions table .

## Resource types defined by Amazon Elastic File System

The following resource types are defined by this service and can be used in the `Resource` element of IAM permission policy statements. Each action in the Actions table identifies the resource types that can be specified with that action. A resource type can also define which condition keys you can include in a policy. These keys are displayed in the last column of the table. For details about the columns in the following table, see The resource types table .

Resource types | ARN | Condition keys
--- | --- | ---
file-system | `arn:$ { Partition}:elasticfilesystem:$ { Region}:$ { Account}:file-system/$ { FileSystemId}` | aws:ResourceTag/${TagKey}
access-point | `arn:$ { Partition}:elasticfilesystem:$ { Region}:$ { Account}:access-point/$ { AccessPointId}` | aws:ResourceTag/${TagKey}

## Condition keys for Amazon Elastic File System

Amazon Elastic File System defines the following condition keys that can be used in the `Condition` element of an IAM policy. You can use these keys to further refine the conditions under which the policy statement applies. For details about the columns in the following table, see The condition keys table .

To view the global condition keys that are available to all services, see Available global condition keys .

Condition keys | Description | Type
--- | --- | ---
aws:RequestTag/${TagKey} | Filters access by a tag key and value pair that is allowed in the request | String
aws:ResourceTag/${TagKey} | Filters access by a tag key and value pair of a resource | String
aws:TagKeys | Filters access by a list of tag keys that are allowed in the request | String
elasticfilesystem:AccessPointArn | Filters access by the ARN of the access point used to mount the file system | String
elasticfilesystem:AccessedViaMountTarget | Filters access by whether the file system is accessed via mount targets | Bool
elasticfilesystem:Encrypted | Filters access by whether users can create only encrypted or unencrypted file systems | Bool
