# Identity and access management for Amazon FSx for Windows File Server
AWS Identity and Access Management (IAM) is an AWS service that helps an administrator securely control access to AWS resources. IAM administrators control who can be *authenticated* (signed in) and *authorized* (have permissions) to use FSx for Windows File Server resources. IAM is an AWS service that you can use with no additional charge.

## Audience
How you use AWS Identity and Access Management (IAM) differs based on your role:
+ **Service user** - request permissions from your administrator if you cannot access features (see [Troubleshooting Amazon FSx for Windows File Server identity and access](security_iam_troubleshoot.md))
+ **Service administrator** - determine user access and submit permission requests (see [How Amazon FSx for Windows File Server works with IAM](security_iam_service-with-iam.md))
+ **IAM administrator** - write policies to manage access (see [Identity-based policy examples for Amazon FSx for Windows File Server](security_iam_id-based-policy-examples.md))
## Authenticating with identities
Authentication is how you sign in to AWS using your identity credentials. You must be authenticated as the AWS account root user, an IAM user, or by assuming an IAM role.
You can sign in as a federated identity using credentials from an identity source like AWS IAM Identity Center (IAM Identity Center), single sign-on authentication, or Google/Facebook credentials. For more information about signing in, see [How to sign in to your AWS account](https://docs.aws.amazon.com/signin/latest/userguide/how-to-sign-in.html) in the *AWS Sign-In User Guide*.
For programmatic access, AWS provides an SDK and CLI to cryptographically sign requests. For more information, see [AWS Signature Version 4 for API requests](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_sigv.html) in the *IAM User Guide*.
### AWS account root user
When you create an AWS account, you begin with one sign-in identity called the AWS account *root user* that has complete access to all AWS services and resources. We strongly recommend that you don't use the root user for everyday tasks. For tasks that require root user credentials, see [Tasks that require root user credentials](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_root-user.html#root-user-tasks) in the *IAM User Guide*.
### Federated identity
As a best practice, require human users to use federation with an identity provider to access AWS services using temporary credentials.
A *federated identity* is a user from your enterprise directory, web identity provider, or Directory Service that accesses AWS services using credentials from an identity source. Federated identities assume roles that provide temporary credentials.
For centralized access management, we recommend AWS IAM Identity Center. For more information, see [What is IAM Identity Center?](https://docs.aws.amazon.com/singlesignon/latest/userguide/what-is.html) in the *AWS IAM Identity Center User Guide*.
### IAM users and groups
An *[IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users.html)* is an identity with specific permissions for a single person or application. We recommend using temporary credentials instead of IAM users with long-term credentials. For more information, see [Require human users to use federation with an identity provider to access AWS using temporary credentials](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#bp-users-federation-idp) in the *IAM User Guide*.
An [https://docs.aws.amazon.com/IAM/latest/UserGuide/id_groups.html](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_groups.html) specifies a collection of IAM users and makes permissions easier to manage for large sets of users. For more information, see [Use cases for IAM users](https://docs.aws.amazon.com/IAM/latest/UserGuide/gs-identities-iam-users.html) in the *IAM User Guide*.
### IAM roles
An *[IAM role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html)* is an identity with specific permissions that provides temporary credentials. You can assume a role by [switching from a user to an IAM role (console)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-console.html) or by calling an AWS CLI or AWS API operation. For more information, see [Methods to assume a role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_manage-assume.html) in the *IAM User Guide*.
IAM roles are useful for federated user access, temporary IAM user permissions, cross-account access, cross-service access, and applications running on Amazon EC2. For more information, see [Cross account resource access in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-cross-account-resource-access.html) in the *IAM User Guide*.
## Managing access using policies
You control access in AWS by creating policies and attaching them to AWS identities or resources. A policy defines permissions when associated with an identity or resource. AWS evaluates these policies when a principal makes a request. Most policies are stored in AWS as JSON documents. For more information about JSON policy documents, see [Overview of JSON policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#access_policies-json) in the *IAM User Guide*.
Using policies, administrators specify who has access to what by defining which **principal** can perform **actions** on what **resources**, and under what **conditions**.
By default, users and roles have no permissions. An IAM administrator creates IAM policies and adds them to roles, which users can then assume. IAM policies define permissions regardless of the method used to perform the operation.
### Identity-based policies
Identity-based policies are JSON permissions policy documents that you attach to an identity (user, group, or role). These policies control what actions identities can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see [Define custom IAM permissions with customer managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create.html) in the *IAM User Guide*.
Identity-based policies can be *inline policies* (embedded directly into a single identity) or *managed policies* (standalone policies attached to multiple identities). To learn how to choose between managed and inline policies, see [Choose between managed policies and inline policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-choosing-managed-or-inline.html) in the *IAM User Guide*.
### Resource-based policies
Resource-based policies are JSON policy documents that you attach to a resource. Examples include IAM *role trust policies* and Amazon S3 *bucket policies*. In services that support resource-based policies, service administrators can use them to control access to a specific resource. You must [specify a principal](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html) in a resource-based policy.
Resource-based policies are inline policies that are located in that service. You can't use AWS managed policies from IAM in a resource-based policy.
### Other policy types
AWS supports additional policy types that can set the maximum permissions granted by more common policy types:
+ **Permissions boundaries** – Set the maximum permissions that an identity-based policy can grant to an IAM entity. For more information, see [Permissions boundaries for IAM entities](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_boundaries.html) in the *IAM User Guide*.
+ **Service control policies (SCPs)** – Specify the maximum permissions for an organization or organizational unit in AWS Organizations. For more information, see [Service control policies](https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_policies_scps.html) in the *AWS Organizations User Guide*.
+ **Resource control policies (RCPs)** – Set the maximum available permissions for resources in your accounts. For more information, see [Resource control policies (RCPs)](https://docs.aws.amazon.com/organizations/latest/userguide/orgs_manage_policies_rcps.html) in the *AWS Organizations User Guide*.
+ **Session policies** – Advanced policies passed as a parameter when creating a temporary session for a role or federated user. For more information, see [Session policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session) in the *IAM User Guide*.
### Multiple policy types
When multiple types of policies apply to a request, the resulting permissions are more complicated to understand. To learn how AWS determines whether to allow a request when multiple policy types are involved, see [Policy evaluation logic](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_evaluation-logic.html) in the *IAM User Guide*.

## Identity-based policies for FSx
**Supports identity-based policies:** Yes
Identity-based policies are JSON permissions policy documents that you can attach to an identity, such as an IAM user, group of users, or role. These policies control what actions users and roles can perform, on which resources, and under what conditions. To learn how to create an identity-based policy, see [Define custom IAM permissions with customer managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create.html) in the *IAM User Guide*.
With IAM identity-based policies, you can specify allowed or denied actions and resources as well as the conditions under which actions are allowed or denied. To learn about all of the elements that you can use in a JSON policy, see [IAM JSON policy elements reference](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html) in the *IAM User Guide*.
### Identity-based policy examples for FSx
To view examples of FSx for Windows File Server identity-based policies, see [Identity-based policy examples for Amazon FSx for Windows File Server](security_iam_id-based-policy-examples.md).
## Resource-based policies within FSx
**Supports resource-based policies:** No
Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM *role trust policies* and Amazon S3 *bucket policies*. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must [specify a principal](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html) in a resource-based policy. Principals can include accounts, users, roles, federated users, or AWS services.
To enable cross-account access, you can specify an entire account or IAM entities in another account as the principal in a resource-based policy. For more information, see [Cross account resource access in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-cross-account-resource-access.html) in the *IAM User Guide*.
## Policy actions for FSx
**Supports policy actions:** Yes
Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**.
The `Action` element of a JSON policy describes the actions that you can use to allow or deny access in a policy. Include actions in a policy to grant permissions to perform the associated operation.
To see a list of FSx actions, see [Actions defined by Amazon FSx for Windows File Server](https://docs.aws.amazon.com/service-authorization/latest/reference/list_your_service.html#your_service-actions-as-permissions) in the *Service Authorization Reference*.
Policy actions in FSx use the following prefix before the action:
```
fsx
```
To specify multiple actions in a single statement, separate them with commas.
```
"Action": [
"fsx:action1",
"fsx:action2"
]
```
To view examples of FSx for Windows File Server identity-based policies, see [Identity-based policy examples for Amazon FSx for Windows File Server](security_iam_id-based-policy-examples.md).
## Policy resources for FSx
**Supports policy resources:** Yes
Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**.
The `Resource` JSON policy element specifies the object or objects to which the action applies. As a best practice, specify a resource using its [Amazon Resource Name (ARN)](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference-arns.html). For actions that don't support resource-level permissions, use a wildcard (\$1) to indicate that the statement applies to all resources.
```
"Resource": "*"
```
To see a list of FSx resource types and their ARNs, see [Resources defined by Amazon FSx for Windows File Server](https://docs.aws.amazon.com/service-authorization/latest/reference/list_your_service.html#your_service-resources-for-iam-policies) in the *Service Authorization Reference*. To learn with which actions you can specify the ARN of each resource, see [Actions defined by Amazon FSx for Windows File Server](https://docs.aws.amazon.com/service-authorization/latest/reference/list_your_service.html#your_service-actions-as-permissions).
To view examples of FSx for Windows File Server identity-based policies, see [Identity-based policy examples for Amazon FSx for Windows File Server](security_iam_id-based-policy-examples.md).
## Policy condition keys for FSx
**Supports service-specific policy condition keys:** Yes
Administrators can use AWS JSON policies to specify who has access to what. That is, which **principal** can perform **actions** on what **resources**, and under what **conditions**.
The `Condition` element specifies when statements execute based on defined criteria. You can create conditional expressions that use [condition operators](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition_operators.html), such as equals or less than, to match the condition in the policy with values in the request. To see all AWS global condition keys, see [AWS global condition context keys](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_condition-keys.html) in the *IAM User Guide*.
To see a list of FSx condition keys, see [Condition keys for Amazon FSx for Windows File Server](https://docs.aws.amazon.com/service-authorization/latest/reference/list_your_service.html#your_service-policy-keys) in the *Service Authorization Reference*. To learn with which actions and resources you can use a condition key, see [Actions defined by Amazon FSx for Windows File Server](https://docs.aws.amazon.com/service-authorization/latest/reference/list_your_service.html#your_service-actions-as-permissions).
To view examples of FSx for Windows File Server identity-based policies, see [Identity-based policy examples for Amazon FSx for Windows File Server](security_iam_id-based-policy-examples.md).
## ACLs in FSx
**Supports ACLs:** No
Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format.
## ABAC with FSx
**Supports ABAC (tags in policies):** Yes
Attribute-based access control (ABAC) is an authorization strategy that defines permissions based on attributes called tags. You can attach tags to IAM entities and AWS resources, then design ABAC policies to allow operations when the principal's tag matches the tag on the resource.
To control access based on tags, you provide tag information in the [condition element](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) of a policy using the `aws:ResourceTag/key-name`, `aws:RequestTag/key-name`, or `aws:TagKeys` condition keys.
If a service supports all three condition keys for every resource type, then the value is **Yes** for the service. If a service supports all three condition keys for only some resource types, then the value is **Partial**.
For more information about ABAC, see [Define permissions with ABAC authorization](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction_attribute-based-access-control.html) in the *IAM User Guide*. To view a tutorial with steps for setting up ABAC, see [Use attribute-based access control (ABAC)](https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_attribute-based-access-control.html) in the *IAM User Guide*.
## Using temporary credentials with FSx
**Supports temporary credentials:** Yes
Temporary credentials provide short-term access to AWS resources and are automatically created when you use federation or switch roles. AWS recommends that you dynamically generate temporary credentials instead of using long-term access keys. For more information, see [Temporary security credentials in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html) and [AWS services that work with IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) in the *IAM User Guide*.
## Forward access sessions for FSx
**Supports forward access sessions (FAS):** Yes
Forward access sessions (FAS) use the permissions of the principal calling an AWS service, combined with the requesting AWS service to make requests to downstream services. For policy details when making FAS requests, see [Forward access sessions](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_forward_access_sessions.html).
## Service roles for FSx
**Supports service roles:** No
A service role is an [IAM role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html) that a service assumes to perform actions on your behalf. An IAM administrator can create, modify, and delete a service role from within IAM. For more information, see [Create a role to delegate permissions to an AWS service](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create_for-service.html) in the *IAM User Guide*.
**Warning**
Changing the permissions for a service role might break FSx functionality. Edit service roles only when FSx provides guidance to do so.
## Service-linked roles for FSx
**Supports service-linked roles:** Yes
A service-linked role is a type of service role that is linked to an AWS service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your AWS account and are owned by the service. An IAM administrator can view, but not edit the permissions for service-linked roles.
For details about creating or managing FSx for Windows File Server service-linked roles, see [Using service-linked roles for FSx for Windows File Server](using-service-linked-roles.md).
# Identity-based policy examples for Amazon FSx for Windows File Server
By default, users and roles don't have permission to create or modify FSx for Windows File Server resources. To grant users permission to perform actions on the resources that they need, an IAM administrator can create IAM policies.
To learn how to create an IAM identity-based policy by using these example JSON policy documents, see [Create IAM policies (console)](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create-console.html) in the *IAM User Guide*.
For details about actions and resource types defined by FSx, including the format of the ARNs for each of the resource types, see [Actions, resources, and condition keys for Amazon FSx for Windows File Server](https://docs.aws.amazon.com/service-authorization/latest/reference/list_your_service.html) in the *Service Authorization Reference*.

## Policy best practices
Identity-based policies determine whether someone can create, access, or delete FSx for Windows File Server resources in your account. These actions can incur costs for your AWS account. When you create or edit identity-based policies, follow these guidelines and recommendations:
+ **Get started with AWS managed policies and move toward least-privilege permissions** – To get started granting permissions to your users and workloads, use the *AWS managed policies* that grant permissions for many common use cases. They are available in your AWS account. We recommend that you reduce permissions further by defining AWS customer managed policies that are specific to your use cases. For more information, see [AWS managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) or [AWS managed policies for job functions](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_job-functions.html) in the *IAM User Guide*.
+ **Apply least-privilege permissions** – When you set permissions with IAM policies, grant only the permissions required to perform a task. You do this by defining the actions that can be taken on specific resources under specific conditions, also known as *least-privilege permissions*. For more information about using IAM to apply permissions, see [ Policies and permissions in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html) in the *IAM User Guide*.
+ **Use conditions in IAM policies to further restrict access** – You can add a condition to your policies to limit access to actions and resources. For example, you can write a policy condition to specify that all requests must be sent using SSL. You can also use conditions to grant access to service actions if they are used through a specific AWS service, such as CloudFormation. For more information, see [ IAM JSON policy elements: Condition](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition.html) in the *IAM User Guide*.
+ **Use IAM Access Analyzer to validate your IAM policies to ensure secure and functional permissions** – IAM Access Analyzer validates new and existing policies so that the policies adhere to the IAM policy language (JSON) and IAM best practices. IAM Access Analyzer provides more than 100 policy checks and actionable recommendations to help you author secure and functional policies. For more information, see [Validate policies with IAM Access Analyzer](https://docs.aws.amazon.com/IAM/latest/UserGuide/access-analyzer-policy-validation.html) in the *IAM User Guide*.
+ **Require multi-factor authentication (MFA)** – If you have a scenario that requires IAM users or a root user in your AWS account, turn on MFA for additional security. To require MFA when API operations are called, add MFA conditions to your policies. For more information, see [ Secure API access with MFA](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_mfa_configure-api-require.html) in the *IAM User Guide*.
For more information about best practices in IAM, see [Security best practices in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) in the *IAM User Guide*.
## Using the FSx console
To access the Amazon FSx for Windows File Server console, you must have a minimum set of permissions. These permissions must allow you to list and view details about the FSx for Windows File Server resources in your AWS account. If you create an identity-based policy that is more restrictive than the minimum required permissions, the console won't function as intended for entities (users or roles) with that policy.
You don't need to allow minimum console permissions for users that are making calls only to the AWS CLI or the AWS API. Instead, allow access to only the actions that match the API operation that they're trying to perform.
To ensure that users and roles can still use the FSx console, also attach the FSx `AmazonFSxConsoleReadOnlyAccess` AWS managed policy to the entities. For more information, see [Adding permissions to a user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_change-permissions.html#users_change_permissions-add-console) in the *IAM User Guide*.
## Allow users to view their own permissions
This example shows how you might create a policy that allows IAM users to view the inline and managed policies that are attached to their user identity. This policy includes permissions to complete this action on the console or programmatically using the AWS CLI or AWS API.

# AWS managed policies for Amazon FSx for Windows File Server
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](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#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](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies) in the *IAM User Guide*.
## AmazonFSxServiceRolePolicy
Allows Amazon FSx to manage AWS resources on your behalf. See [Using service-linked roles for FSx for Windows File Server](using-service-linked-roles.md) to learn more.
## AWS managed policy: AmazonFSxDeleteServiceLinkedRoleAccess
You can't attach `AmazonFSxDeleteServiceLinkedRoleAccess` to your IAM entities. This policy is linked to a service and used only with the service-linked role for that service. You cannot attach, detach, modify, or delete this policy. For more information, see [Using service-linked roles for FSx for Windows File Server](using-service-linked-roles.md).
This policy grants administrative permissions that allow Amazon FSx to delete its Service Linked Role for Amazon S3 access, used only by Amazon FSx for Lustre.
**Permissions details**
This policy includes permissions in `iam` to allow Amazon FSx to view, delete, and view the deletion status for the FSx Service Linked Roles for Amazon S3 access.
To view the permissions for this policy, see [AmazonFSxDeleteServiceLinkedRoleAccess](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/FSxDeleteServiceLinkedRoleAccess.html) in the AWS Managed Policy Reference Guide.
## AWS managed policy: AmazonFSxFullAccess
You can attach AmazonFSxFullAccess to your IAM entities. Amazon FSx also attaches this policy to a service role that allows Amazon FSx to perform actions on your behalf.
Provides full access to Amazon FSx and access to related AWS services.
**Permissions details**
This policy includes the following permissions.
+ `fsx` – Allows principals full access to perform all Amazon FSx actions, except for `BypassSnaplockEnterpriseRetention`.
+ `ds` – Allows principals to view information about the Directory Service directories.
+ `ec2`
+ Allows principals to create tags under the specified conditions.
+ To provide enhanced security group validation of all security groups that can be used with a VPC.
+ `iam` – Allows principles to create an Amazon FSx service linked role on the user's behalf. This is required so that Amazon FSx can manage AWS resources on the user's behalf.

# Troubleshooting Amazon FSx for Windows File Server identity and access
Use the following information to help you diagnose and fix common issues that you might encounter when working with FSx for Windows File Server and IAM.
**Topics**
+ [I am not authorized to perform an action in FSx](#security_iam_troubleshoot-no-permissions)
+ [I am not authorized to perform iam:PassRole](#security_iam_troubleshoot-passrole)
+ [I want to allow people outside of my AWS account to access my FSx resources](#security_iam_troubleshoot-cross-account-access)
## I am not authorized to perform an action in FSx
If you receive an error that you're not authorized to perform an action, your policies must be updated to allow you to perform the action.
The following example error occurs when the `mateojackson` IAM user tries to use the console to view details about a fictional `my-example-widget` resource but doesn't have the fictional `fsx:GetWidget` permissions.
```
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: fsx:GetWidget on resource: my-example-widget
```
In this case, the policy for the `mateojackson` user must be updated to allow access to the `my-example-widget` resource by using the `fsx:GetWidget` action.
If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials.
## I am not authorized to perform iam:PassRole
If you receive an error that you're not authorized to perform the `iam:PassRole` action, your policies must be updated to allow you to pass a role to FSx for Windows File Server.
Some AWS services allow you to pass an existing role to that service instead of creating a new service role or service-linked role. To do this, you must have permissions to pass the role to the service.
The following example error occurs when an IAM user named `marymajor` tries to use the console to perform an action in FSx for Windows File Server. However, the action requires the service to have permissions that are granted by a service role. Mary does not have permissions to pass the role to the service.
```
User: arn:aws:iam::123456789012:user/marymajor is not authorized to perform: iam:PassRole
```
In this case, Mary's policies must be updated to allow her to perform the `iam:PassRole` action.
If you need help, contact your AWS administrator. Your administrator is the person who provided you with your sign-in credentials.
## I want to allow people outside of my AWS account to access my FSx resources
You can create a role that users in other accounts or people outside of your organization can use to access your resources. You can specify who is trusted to assume the role. For services that support resource-based policies or access control lists (ACLs), you can use those policies to grant people access to your resources.
To learn more, consult the following:
+ To learn whether FSx for Windows File Server supports these features, see [How Amazon FSx for Windows File Server works with IAM](security_iam_service-with-iam.md).
+ To learn how to provide access to your resources across AWS accounts that you own, see [Providing access to an IAM user in another AWS account that you own](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_aws-accounts.html) in the *IAM User Guide*.

# Using tags with Amazon FSx
You can use tags to control access to Amazon FSx resources and to implement attribute-based access control (ABAC). Users need to have permission to apply tags to Amazon FSx resources during creation.
## Grant permission to tag resources during creation
Some resource-creating FSx for Windows File Server API actions enable you to specify tags when you create the resource. You can use resource tags to implement attribute-based access control (ABAC). For more information, see [ What is ABAC for AWS](https://docs.aws.amazon.com/IAM/latest/UserGuide/introduction_attribute-based-access-control.html) in the *IAM User Guide*.
To enable users to tag resources on creation, they must have permissions to use the action that creates the resource, such as `fsx:CreateFileSystem` or `fsx:CreateBackup`. If tags are specified in the resource-creating action, Amazon performs additional authorization on the `fsx:TagResource` action to verify if users have permissions to create tags. Therefore, users must also have explicit permissions to use the `fsx:TagResource` action.
The following example demonstrates a policy that allows users to create file systems and apply tags to file systems during creation in a specific AWS account.
```
{
"Statement": [
{
"Effect": "Allow",
"Action": [
"fsx:CreateFileSystem",
"fsx:TagResource"
],
"Resource": "arn:aws:fsx:region:account-id:file-system/*"
}
]
}
```
Similarly, the following policy allows users to create backups on a specific file system and apply any tags to the backup during backup creation.
```
{
"Statement": [
{
"Effect": "Allow",
"Action": [
"fsx:CreateBackup"
],
"Resource": "arn:aws:fsx:region:account-id:file-system/file-system-id*"
},
{
"Effect": "Allow",
"Action": [
"fsx:TagResource"
],
"Resource": "arn:aws:fsx:region:account-id:backup/*"
}
]
}
```
The `fsx:TagResource` action is only evaluated if tags are applied during the resource-creating action. Therefore, a user that has permissions to create a resource (assuming there are no tagging conditions) does not require permissions to use the `fsx:TagResource` action if no tags are specified in the request. However, if the user attempts to create a resource with tags, the request fails if the user does not have permissions to use the `fsx:TagResource` action.
For more information about tagging Amazon FSx resources, see [Tagging your Amazon FSx resources](tag-resources.md). For more information about using tags to control access to FSx resources, see [Using tags to control access to your Amazon FSx resources](#restrict-fsx-access-tags).
## Using tags to control access to your Amazon FSx resources
To control access to Amazon FSx resources and actions, you can use AWS Identity and Access Management (IAM) policies based on tags. You can provide the control in two ways:
1. Control access to Amazon FSx resources based on the tags on those resources.
1. Control what tags can be passed in an IAM request condition.
For information about how to use tags to control access to AWS resources, see [Controlling access using tags](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_tags.html) in the *IAM User Guide*. For more information about tagging Amazon FSx resources at creation, see [Grant permission to tag resources during creation](#supported-iam-actions-tagging). For more information about tagging resources, see [Tagging your Amazon FSx resources](tag-resources.md).
### Controlling access based on tags on a resource
To control what actions a user or role can perform on an Amazon FSx resource, you can use tags on the resource. For example, you might want to allow or deny specific API operations on a file system resource based on the key-value pair of the tag on the resource.
**Example policy – Create a file system on when providing a specific tag**
This policy allows the user to create a file system only when they tag it with a specific tag key value pair, in this example, `key=Department, value=Finance`.
```
{
"Effect": "Allow",
"Action": [
"fsx:CreateFileSystem",
"fsx:TagResource"
],
"Resource": "arn:aws:fsx:region:account-id:file-system/*",
"Condition": {
"StringEquals": {
"aws:RequestTag/Department": "Finance"
}
}
}
```
**Example policy – Create backups only of Amazon FSx file systems with a specific tag**
This policy allows users to create backups only of file systems that are tagged with the key value pair `key=Department, value=Finance`, and the backup will be created with the tag `Deparment=Finance`.

# Using service-linked roles for FSx for Windows File Server
Amazon FSx for Windows File Server uses AWS Identity and Access Management (IAM)[ service-linked roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role). A service-linked role is a unique type of IAM role that is linked directly to FSx for Windows File Server. Service-linked roles are predefined by FSx for Windows File Server and include all the permissions that the service requires to call other AWS services on your behalf.
A service-linked role makes setting up FSx for Windows File Server easier because you don’t have to manually add the necessary permissions. FSx for Windows File Server defines the permissions of its service-linked roles, and unless defined otherwise, only FSx for Windows File Server can assume its roles. The defined permissions include the trust policy and the permissions policy, and that permissions policy cannot be attached to any other IAM entity.
You can delete a service-linked role only after first deleting their related resources. This protects your FSx for Windows File Server resources because you can't inadvertently remove permission to access the resources.
For information about other services that support service-linked roles, see [AWS Services That Work with IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) and look for the services that have **Yes **in the **Service-Linked Role** column. Choose a **Yes** with a link to view the service-linked role documentation for that service.
## Service-linked role permissions for FSx for Windows File Server
FSx for Windows File Server uses the service-linked role named `AWSServiceRoleForAmazonFSx` – Which performs certain actions in your account, like creating Elastic Network Interfaces for your file systems in your VPC.
The role permissions policy allows FSx for Windows File Server to complete the following actions on the all applicable AWS resources:
You can't attach AmazonFSxServiceRolePolicy to your IAM entities. This policy is attached to a service-linked role that allows FSx to manage AWS resources on your behalf. For more information, see [Using service-linked roles for FSx for Windows File Server](#using-service-linked-roles).
For updates to this policy, see [AmazonFSxServiceRolePolicy](security-iam-awsmanpol.md#security-iam-awsmanpol-AmazonFSxServiceRolePolicy).
This policy grants administrative permissions that allows FSx to manage AWS resources on the user's behalf.
**Permissions details**
The AmazonFSxServiceRolePolicy role permissions are defined by the AmazonFSxServiceRolePolicy AWS managed policy. AmazonFSxServiceRolePolicy has the following permissions:
**Note**
AmazonFSxServiceRolePolicy is used by all Amazon FSx file system types; some of the listed permissions may not applicable to FSx for Windows.
+ `ds` – Allows FSx to view, authorize, and unauthorize applications in your Directory Service directory.
+ `ec2` – Allows FSx to do the following:
+ View, create, and disassociate network interfaces associated with an Amazon FSx file system.
+ View one or more Elastic IP addresses associated with an Amazon FSx file system.
+ View Amazon VPCs, security groups, and subnets associated with an Amazon FSx file system.
+ Assign IPv6 addresses to customer network interfaces that have an `AmazonFSx.FileSystemId` tag.
+ Unassign IPv6 addresses from customer network interfaces that have an `AmazonFSx.FileSystemId` tag.
+ To provide enhanced security group validation of all security groups that can be used with a VPC.
+ Create a permission for an AWS-authorized user to perform certain operations on a network interface.
+ `cloudwatch` – Allows FSx to publish metric data points to CloudWatch under the AWS/FSx namespace.
+ `route53` – Allows FSx to associate an Amazon VPC with a private hosted zone.
+ `logs` – Allows FSx to describe and write to CloudWatch Logs log streams. This is so that users can send file access audit logs for an FSx for Windows File Server file system to a CloudWatch Logs stream.
+ `firehose` – Allows FSx to describe and write to Amazon Data Firehose delivery streams. This is so that users can publish the file access audit logs for an FSx for Windows File Server file system to an Amazon Data Firehose delivery stream.

Any updates to this policy are described in [Amazon FSx updates to AWS managed policies](security-iam-awsmanpol.md#security-iam-awsmanpol-updates).
You must configure permissions to allow an IAM entity (such as a user, group, or role) to create, edit, or delete a service-linked role. For more information, see [Service-Linked Role Permissions](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#service-linked-role-permissions) in the *IAM User Guide*.
## Creating a service-linked role for FSx for Windows File Server
You don't need to manually create a service-linked role. When you create a file system in the AWS Management Console, the IAM CLI, or the IAM API, FSx for Windows File Server creates the service-linked role for you.
**Important**
This service-linked role can appear in your account if you completed an action in another service that uses the features supported by this role. To learn more, see [A New Role Appeared in My IAM Account](https://docs.aws.amazon.com/IAM/latest/UserGuide/troubleshoot_roles.html#troubleshoot_roles_new-role-appeared).
If you delete this service-linked role, and then need to create it again, you can use the same process to recreate the role in your account. When you create a file system, FSx for Windows File Server creates the service-linked role for you again.
## Editing a service-linked role for FSx for Windows File Server
FSx for Windows File Server does not allow you to edit the service-linked role. After you create a service-linked role, you cannot change the name of the role because various entities might reference the role. However, you can edit the description of the role using IAM. For more information, see [Editing a Service-Linked Role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#edit-service-linked-role) in the *IAM User Guide*.
## Deleting a service-linked role for FSx for Windows File Server
If you no longer need to use a feature or service that requires a service-linked role, we recommend that you delete that role. That way you don’t have an unused entity that is not actively monitored or maintained. However, you must delete all of your file systems and backups before you can manually delete the service-linked role.
**Note**
If the FSx for Windows File Server service is using the role when you try to delete the resources, then the deletion might fail. If that happens, wait for a few minutes and try the operation again.
**To manually delete the service-linked role using IAM**
Use the IAM console, the IAM CLI, or the IAM API to delete the service-linked role. For more information, see [Deleting a Service-Linked Role](https://docs.aws.amazon.com/IAM/latest/UserGuide/using-service-linked-roles.html#delete-service-linked-role) in the *IAM User Guide*.
## Supported regions for FSx for Windows File Server service-linked roles
FSx for Windows File Server supports using service-linked roles in all of the regions where the service is available. For more information, see [AWS Regions and Endpoints](https://docs.aws.amazon.com/general/latest/gr/rande.html).
