# Security in Amazon FSx for Lustre
<a name="security"></a>

Cloud security at AWS is the highest priority. As an AWS customer, you benefit from data centers and network architectures that are built to meet the requirements of the most security-sensitive organizations.

Security is a shared responsibility between AWS and you. The [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) describes this as security *of* the cloud and security *in* the cloud:
+ **Security of the cloud** – AWS is responsible for protecting the infrastructure that runs AWS services in the Amazon Web Services Cloud. AWS also provides you with services that you can use securely. Third-party auditors regularly test and verify the effectiveness of our security as part of the [AWS Compliance Programs](https://aws.amazon.com/compliance/programs/). To learn about the compliance programs that apply to Amazon FSx for Lustre, see [AWS Services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/).
+ **Security in the cloud** – Your responsibility is determined by the AWS service that you use. You are also responsible for other factors including the sensitivity of your data, your company’s requirements, and applicable laws and regulations. 

This documentation helps you understand how to apply the shared responsibility model when using Amazon FSx for Lustre. The following topics show you how to configure Amazon FSx to meet your security and compliance objectives. You also learn how to use other Amazon services that help you to monitor and secure your Amazon FSx for Lustre resources. 

Following, you can find a description of security considerations for working with Amazon FSx.

# Data protection in Amazon FSx for Lustre
<a name="data-protection"></a>

The AWS [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) applies to data protection in Amazon FSx for Lustre. As described in this model, AWS is responsible for protecting the global infrastructure that runs all of the AWS Cloud. You are responsible for maintaining control over your content that is hosted on this infrastructure. You are also responsible for the security configuration and management tasks for the AWS services that you use. For more information about data privacy, see the [Data Privacy FAQ](https://aws.amazon.com/compliance/data-privacy-faq/). For information about data protection in Europe, see the [AWS Shared Responsibility Model and GDPR](https://aws.amazon.com/blogs/security/the-aws-shared-responsibility-model-and-gdpr/) blog post on the *AWS Security Blog*.

For data protection purposes, we recommend that you protect AWS account credentials and set up individual users with AWS IAM Identity Center or AWS Identity and Access Management (IAM). That way, each user is given only the permissions necessary to fulfill their job duties. We also recommend that you secure your data in the following ways:
+ Use multi-factor authentication (MFA) with each account.
+ Use SSL/TLS to communicate with AWS resources. We require TLS 1.2 and recommend TLS 1.3.
+ Set up API and user activity logging with AWS CloudTrail. For information about using CloudTrail trails to capture AWS activities, see [Working with CloudTrail trails](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-trails.html) in the *AWS CloudTrail User Guide*.
+ Use AWS encryption solutions, along with all default security controls within AWS services.
+ Use advanced managed security services such as Amazon Macie, which assists in discovering and securing sensitive data that is stored in Amazon S3.
+ If you require FIPS 140-3 validated cryptographic modules when accessing AWS through a command line interface or an API, use a FIPS endpoint. For more information about the available FIPS endpoints, see [Federal Information Processing Standard (FIPS) 140-3](https://aws.amazon.com/compliance/fips/).

We strongly recommend that you never put confidential or sensitive information, such as your customers' email addresses, into tags or free-form text fields such as a **Name** field. This includes when you work with Amazon FSx or other AWS services using the console, API, AWS CLI, or AWS SDKs. Any data that you enter into tags or free-form text fields used for names may be used for billing or diagnostic logs. If you provide a URL to an external server, we strongly recommend that you do not include credentials information in the URL to validate your request to that server.

# Data encryption in Amazon FSx for Lustre
<a name="encryption-fsxl"></a>

Amazon FSx for Lustre supports two forms of encryption for file systems, encryption of data at rest and encryption in transit. Encryption of data at rest is automatically enabled when creating an Amazon FSx file system. Encryption of data in transit is automatically enabled when you access an Amazon FSx file system from [Amazon EC2 instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/data-protection.html#encryption-transit) that support this feature.

## When to use encryption
<a name="whenencrypt"></a>

If your organization is subject to corporate or regulatory policies that require encryption of data and metadata at rest, we recommend creating an encrypted file system and mounting your file system using encryption of data in transit.

For more information about creating a file system encrypted at rest using the console, see [Create your Amazon FSx for Lustre file system](getting-started.md#getting-started-step1).

# Encrypting data at rest
<a name="encryption-at-rest"></a>

Encryption of data at rest is automatically enabled when you create an Amazon FSx for Lustre file system through the AWS Management Console, the AWS CLI, or programmatically through the Amazon FSx API or one of the AWS SDKs. Your organization might require the encryption of all data that meets a specific classification or is associated with a particular application, workload, or environment. If you create a persistent file system, you can specify the AWS KMS key to encrypt the data with. If you create a scratch file system, the data is encrypted using keys managed by Amazon FSx. For more information about creating a file system encrypted at rest using the console, see [Create your Amazon FSx for Lustre file system](getting-started.md#getting-started-step1).

**Note**  
The AWS key management infrastructure uses Federal Information Processing Standards (FIPS) 140-2 approved cryptographic algorithms. The infrastructure is consistent with National Institute of Standards and Technology (NIST) 800-57 recommendations.

For more information on how FSx for Lustre uses AWS KMS, see [How Amazon FSx for Lustre uses AWS KMS](#FSXKMS).

## How encryption at rest works
<a name="howencrypt"></a>

In an encrypted file system, data and metadata are automatically encrypted before being written to the file system. Similarly, as data and metadata are read, they are automatically decrypted before being presented to the application. These processes are handled transparently by Amazon FSx for Lustre, so you don't have to modify your applications.

Amazon FSx for Lustre uses industry-standard AES-256 encryption algorithm to encrypt file system data at rest. For more information, see [Cryptography Basics](https://docs.aws.amazon.com/kms/latest/developerguide/crypto-intro.html) in the *AWS Key Management Service Developer Guide*.

## How Amazon FSx for Lustre uses AWS KMS
<a name="FSXKMS"></a>

 Amazon FSx for Lustre encrypts data automatically before it is written to the file system, and automatically decrypts data as it is read. Data is encrypted using an XTS-AES-256 block cipher. All scratch FSx for Lustre file systems are encrypted at rest with keys managed by AWS KMS. Amazon FSx for Lustre integrates with AWS KMS for key management. The keys used to encrypt scratch file systems at-rest are unique per file system and destroyed after the file system is deleted. For persistent file systems, you choose the KMS key used to encrypt and decrypt data. You specify which key to use when you create a persistent file system. You can enable, disable, or revoke grants on this KMS key. This KMS key can be one of the two following types:
+ **AWS managed key for Amazon FSx** – This is the default KMS key. You're not charged to create and store a KMS key, but there are usage charges. For more information, see [AWS Key Management Service pricing](https://aws.amazon.com/kms/pricing/).
+ **Customer managed key** – This is the most flexible KMS key to use, because you can configure its key policies and grants for multiple users or services. For more information on creating customer managed keys, see [Creating keys](https://docs.aws.amazon.com/kms/latest/developerguide/create-keys.html) in the* AWS Key Management Service Developer Guide.*

If you use a customer managed key as your KMS key for file data encryption and decryption, you can enable key rotation. When you enable key rotation, AWS KMS automatically rotates your key once per year. Additionally, with a customer managed key, you can choose when to disable, re-enable, delete, or revoke access to your customer managed key at any time. 

**Important**  
Amazon FSx accepts only symmetric encryption KMS keys. You can't use asymmetric KMS keys with Amazon FSx.

### Amazon FSx key policies for AWS KMS
<a name="FSxKMSPolicy"></a>

Key policies are the primary way to control access to KMS keys. For more information on key policies, see [Using key policies in AWS KMS](https://docs.aws.amazon.com/kms/latest/developerguide/key-policies.html) in the *AWS Key Management Service Developer Guide. *The following list describes all the AWS KMS–related permissions supported by Amazon FSx for encrypted at rest file systems:
+ **kms:Encrypt** – (Optional) Encrypts plaintext into ciphertext. This permission is included in the default key policy.
+ **kms:Decrypt** – (Required) Decrypts ciphertext. Ciphertext is plaintext that has been previously encrypted. This permission is included in the default key policy.
+ **kms:ReEncrypt** – (Optional) Encrypts data on the server side with a new KMS key, without exposing the plaintext of the data on the client side. The data is first decrypted and then re-encrypted. This permission is included in the default key policy.
+ **kms:GenerateDataKeyWithoutPlaintext** – (Required) Returns a data encryption key encrypted under a KMS key. This permission is included in the default key policy under **kms:GenerateDataKey\$1**.
+ **kms:CreateGrant** – (Required) Adds a grant to a key to specify who can use the key and under what conditions. Grants are alternate permission mechanisms to key policies. For more information on grants, see [Using grants](https://docs.aws.amazon.com/kms/latest/developerguide/grants.html) in the *AWS Key Management Service Developer Guide.* This permission is included in the default key policy.
+ **kms:DescribeKey** – (Required) Provides detailed information about the specified KMS key. This permission is included in the default key policy.
+ **kms:ListAliases** – (Optional) Lists all of the key aliases in the account. When you use the console to create an encrypted file system, this permission populates the list to select the KMS key. We recommend using this permission to provide the best user experience. This permission is included in the default key policy.

# Encrypting data in transit
<a name="encryption-in-transit-fsxl"></a>

Scratch 2 and persistent file systems can automatically encrypt data in transit when the file system is accessed from Amazon EC2 instances that support encryption in transit, and also for all communications between hosts within the file system. To learn which EC2 instances support encryption in transit, see [Encryption in transit](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/data-protection.html#encryption-transit) in the *Amazon EC2 User Guide*.

For a list of AWS Regions in which Amazon FSx for Lustre is available, see [Deployment type availability](using-fsx-lustre.md#persistent-deployment-regions). 

# Internetwork traffic privacy
<a name="internetwork-privacy"></a>

This topic describes how Amazon FSx secures connections from the service to other locations.

## Traffic between Amazon FSx and on-premises clients
<a name="inter-network-traffic-privacy-on-prem"></a>

You have two connectivity options between your private network and AWS:
+ An AWS Site-to-Site VPN connection. For more information, see [What is AWS Site-to-Site VPN?](https://docs.aws.amazon.com/vpn/latest/s2svpn/VPC_VPN.html)
+ An AWS Direct Connect connection. For more information, see [What is AWS Direct Connect?](https://docs.aws.amazon.com/directconnect/latest/UserGuide/Welcome.html)

You can access FSx for Lustre over the network to reach AWS-published API operations for performing administrative tasks and Lustre ports to interact with the file system.

### Encrypting API traffic
<a name="encrypt-api-traffic"></a>

To access AWS-published API operations, clients must support Transport Layer Security (TLS) 1.2 or later. We require TLS 1.2 and recommend TLS 1.3. Clients must also support cipher suites with Perfect Forward Secrecy (PFS), such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Diffie-Hellman Ephemeral (ECDHE). Most modern systems such as Java 7 and later support these modes. Additionally, requests must be signed by using an access key ID and a secret access key that is associated with an IAM principal. Or you can use the [AWS Security Token Service (STS)](https://docs.aws.amazon.com/STS/latest/APIReference/Welcome.html) to generate temporary security credentials to sign requests.

### Encrypting data traffic
<a name="encrypt-data-traffic"></a>

 Encryption of data in transit is enabled from supported EC2 instances accessing the file systems from within the AWS Cloud. For more information, see [Encrypting data in transit](encryption-in-transit-fsxl.md). FSx for Lustre does not natively offer encryption in transit between on-premise clients and file systems. 

# Identity and access management for Amazon FSx for Lustre
<a name="security-iam"></a>





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 Amazon FSx resources. IAM is an AWS service that you can use with no additional charge.

## Audience
<a name="security_iam_audience"></a>

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 Lustre identity and access](security_iam_troubleshoot.md))
+ **Service administrator** - determine user access and submit permission requests (see [How Amazon FSx for Lustre 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 Lustre](security_iam_id-based-policy-examples.md))

## Authenticating with identities
<a name="security_iam_authentication"></a>

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
<a name="security_iam_authentication-rootuser"></a>

 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
<a name="security_iam_authentication-federated"></a>

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
<a name="security_iam_authentication-iamuser"></a>

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
<a name="security_iam_authentication-iamrole"></a>

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
<a name="security_iam_access-manage"></a>

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
<a name="security_iam_access-manage-id-based-policies"></a>

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
<a name="security_iam_access-manage-resource-based-policies"></a>

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
<a name="security_iam_access-manage-other-policies"></a>

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
<a name="security_iam_access-manage-multiple-policies"></a>

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 Amazon FSx
<a name="security_iam_service-with-iam-id-based-policies"></a>

**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 Amazon FSx
<a name="security_iam_service-with-iam-id-based-policies-examples"></a>



To view examples of Amazon FSx identity-based policies, see [Identity-based policy examples for Amazon FSx for Lustre](security_iam_id-based-policy-examples.md).

## Resource-based policies within Amazon FSx
<a name="security_iam_service-with-iam-resource-based-policies"></a>

**Supports resource-based policies:** No 

## Policy actions for Amazon FSx
<a name="security_iam_service-with-iam-id-based-policies-actions"></a>

**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 Amazon FSx actions, see [Actions defined by Amazon FSx for Lustre](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonfsx.html#amazonfsx-actions-as-permissions) in the *Service Authorization Reference*.

Policy actions in Amazon 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 Amazon FSx identity-based policies, see [Identity-based policy examples for Amazon FSx for Lustre](security_iam_id-based-policy-examples.md).

## Policy resources for Amazon FSx
<a name="security_iam_service-with-iam-id-based-policies-resources"></a>

**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": "*"

## Policy condition keys for Amazon FSx
<a name="security_iam_service-with-iam-id-based-policies-conditionkeys"></a>

**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 Amazon FSx condition keys, see [Condition keys for Amazon FSx for Lustre](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonfsx.html#amazonfsx-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 Lustre](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonfsx.html#amazonfsx-actions-as-permissions).

## Access control lists (ACLs) in Amazon FSx
<a name="security_iam_service-with-iam-acls"></a>

**Supports ACLs:** No 

## Attribute-based access control (ABAC) with Amazon FSx
<a name="security_iam_service-with-iam-tags"></a>

**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*.

For more information about tagging Amazon FSx resources, see [Tag your Amazon FSx for Lustre resources](tag-resources.md).

To view an example identity-based policy for limiting access to a resource based on the tags on that resource, see [Using tags to control access to your Amazon FSx resources](using-tags-fsx.md#restrict-fsx-access-tags).

## Using Temporary credentials with Amazon FSx
<a name="security_iam_service-with-iam-roles-tempcreds"></a>

**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 Amazon FSx
<a name="security_iam_service-with-iam-principal-permissions"></a>

**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 Amazon FSx
<a name="security_iam_service-with-iam-roles-service"></a>

**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 Amazon FSx functionality. Edit service roles only when Amazon FSx provides guidance to do so.

## Service-linked roles for Amazon FSx
<a name="security_iam_service-with-iam-roles-service-linked"></a>

**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 more information about creating and managing Amazon FSx service-linked roles, see [Using service-linked roles for Amazon FSx](using-service-linked-roles.md).

# Identity-based policy examples for Amazon FSx for Lustre
<a name="security_iam_id-based-policy-examples"></a>

By default, users and roles don't have permission to create or modify Amazon FSx 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 Amazon FSx, including the format of the ARNs for each of the resource types, see [Actions, resources, and condition keys for Amazon FSx for Lustre](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonfsx.html) in the *Service Authorization Reference*.

## Policy best practices
<a name="security_iam_service-with-iam-policy-best-practices"></a>

Identity-based policies determine whether someone can create, access, or delete Amazon FSx 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 Amazon FSx console
<a name="security_iam_id-based-policy-examples-console"></a>

To access the Amazon FSx for Lustre console, you must have a minimum set of permissions. These permissions must allow you to list and view details about the Amazon FSx 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 Amazon FSx console, also attach the `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*.

You can see the `AmazonFSxConsoleReadOnlyAccess` and other Amazon FSx managed service policies in [AWS managed policies for Amazon FSx for Lustre](security-iam-awsmanpol.md).

## Allow users to view their own permissions
<a name="security_iam_id-based-policy-examples-view-own-permissions"></a>

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 Lustre
<a name="security-iam-awsmanpol"></a>

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

# Troubleshooting Amazon FSx for Lustre identity and access
<a name="security_iam_troubleshoot"></a>

Use the following information to help you diagnose and fix common issues that you might encounter when working with Amazon FSx and IAM.

**Topics**
+ [

## I am not authorized to perform an action in Amazon 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 Amazon FSx resources
](#security_iam_troubleshoot-cross-account-access)

## I am not authorized to perform an action in Amazon FSx
<a name="security_iam_troubleshoot-no-permissions"></a>

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
<a name="security_iam_troubleshoot-passrole"></a>

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 Amazon FSx.

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 Amazon FSx. 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 Amazon FSx resources
<a name="security_iam_troubleshoot-cross-account-access"></a>

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 Amazon FSx supports these features, see [How Amazon FSx for Lustre 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
<a name="using-tags-fsx"></a>

You can use tags to control access to Amazon FSx resources and to implement attribute-based access control (ABAC). To apply tags to Amazon FSx resources during creation, users must have certain AWS Identity and Access Management (IAM) permissions.

## Grant permission to tag resources during creation
<a name="supported-iam-actions-tagging"></a>

With some resource-creating Amazon FSx for Lustre API actions, you can specify tags when you create the resource. You can use these 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*.

For users to tag resources on creation, they must have permission to use the action that creates the resource, such as `fsx:CreateFileSystem`. If tags are specified in the resource-creating action, IAM 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 policy allows users to create file systems and apply tags to them 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 evaluated only if tags are applied during the resource-creating action. Therefore, a user who has permissions to create a resource (assuming there are no tagging conditions) does not require permission 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 [Tag your Amazon FSx for Lustre resources](tag-resources.md). For more information about using tags to control access to Amazon FSx for Lustre 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
<a name="restrict-fsx-access-tags"></a>

To control access to Amazon FSx resources and actions, you can use IAM policies based on tags. You can provide this control in two ways:
+ You can control access to Amazon FSx resources based on the tags on those resources.
+ You can control which 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 [Tag your Amazon FSx for Lustre resources](tag-resources.md).

### Controlling access based on tags on a resource
<a name="resource-tag-control"></a>

To control which 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 on file systems with a specific tag**  
This policy allows users to create backups only on 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`.

            }
        }
    ]
}
```

**Example policy – Create a file system with a specific tag from backups with a specific tag**  
This policy allows users to create file systems that are tagged with `Department=Finance` only from backups that are tagged with `Department=Finance`.

                }
            }
        }
    ]
}
```

**Example policy – Delete file systems with specific tags**  
This policy allows a user to delete only file systems that are tagged with `Department=Finance`. If they create a final backup, then it must be tagged with `Department=Finance`. For FSx for Lustre file systems, users need the `fsx:CreateBackup` privilege to create the final backup.

# Using service-linked roles for Amazon FSx
<a name="using-service-linked-roles"></a>

Amazon FSx 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 Amazon FSx. Service-linked roles are predefined by Amazon FSx and include all the permissions that the service requires to call other AWS services on your behalf.

A service-linked role makes setting up Amazon FSx easier because you don’t have to manually add the necessary permissions. Amazon FSx defines the permissions of its service-linked roles, and unless defined otherwise, only Amazon FSx 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 Amazon FSx 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 roles** column. Choose a **Yes** with a link to view the service-linked role documentation for that service.

## Service-linked role permissions for Amazon FSx
<a name="slr-permissions"></a>

Amazon FSx uses two service-linked roles named `AWSServiceRoleForAmazonFSx` and `AWSServiceRoleForFSxS3Access_fs-01234567890` that perform certain actions in your account. Examples of these actions are creating elastic network interfaces for your file systems in your VPC and accessing your data repository in an Amazon S3 bucket. For `AWSServiceRoleForFSxS3Access_fs-01234567890`, this service-linked role is created for each Amazon FSx for Lustre file system you create that is linked to an S3 bucket.

### AWSServiceRoleForAmazonFSx permissions details
<a name="AmazonFSxServiceRolePolicy-permissions"></a>

For `AWSServiceRoleForAmazonFSx`, the role permissions policy allows Amazon FSx to complete the following administrative actions on the user's behalf on all applicable AWS resources:

For updates to this policy, see [AmazonFSxServiceRolePolicy](security-iam-awsmanpol.md#security-iam-awsmanpol-AmazonFSxServiceRolePolicy).

**Note**  
The AWSServiceRoleForAmazonFSx is used by all Amazon FSx file system types; some of the listed permissions are not applicable to FSx for Lustre.
+ `ds` – Allows Amazon FSx to view, authorize, and unauthorize applications in your Directory Service directory.
+ `ec2` – Allows Amazon 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 Amazon FSx to publish metric data points to CloudWatch under the AWS/FSx namespace.
+ `route53` – Allows Amazon FSx to associate an Amazon VPC with a private hosted zone.
+ `logs` – Allows Amazon 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 Amazon 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.

### AWSServiceRoleForFSxS3Access permissions details
<a name="AWSServiceRoleForFSxS3Access-permissions"></a>

For `AWSServiceRoleForFSxS3Access_file-system-id`, the role permissions policy allows Amazon FSx to complete the following actions on an Amazon S3 bucket hosting the data repository for an Amazon FSx for Lustre file system.
+ `s3:AbortMultipartUpload`
+ `s3:DeleteObject`
+ `s3:Get*`
+ `s3:List*`
+ `s3:PutBucketNotification`
+ `s3:PutObject`

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 Amazon FSx
<a name="create-slr"></a>

You don't need to manually create a service-linked role. When you create a file system in the AWS Management Console, the AWS CLI, or the AWS API, Amazon FSx 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, Amazon FSx creates the service-linked role for you again. 

## Editing a service-linked role for Amazon FSx
<a name="edit-slr"></a>

Amazon FSx does not allow you to edit these service-linked roles. 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 Amazon FSx
<a name="delete-slr"></a>

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 Amazon FSx 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 AWSServiceRoleForAmazonFSx 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 Amazon FSx service-linked roles
<a name="slr-regions"></a>

Amazon FSx 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).

# File system access control with Amazon VPC
<a name="limit-access-security-groups"></a>

An Amazon FSx file system is accessible through an elastic network interface that resides in the virtual private cloud (VPC) based on the Amazon VPC service that you associate with your file system. You access your Amazon FSx file system through its DNS name, which maps to the file system's network interface. Only resources within the associated VPC, or a peered VPC, can access your file system's network interface. For more information, see [What is Amazon VPC?](https://docs.aws.amazon.com/vpc/latest/userguide/what-is-amazon-vpc.html) in the* Amazon VPC User Guide.*

**Warning**  
You must not modify or delete the Amazon FSx elastic network interface. Modifying or deleting the network interface can cause a permanent loss of connection between your VPC and your file system.

## Amazon VPC Security Groups
<a name="fsx-vpc-security-groups"></a>

To further control network traffic going through your file system's network interface within your VPC, you use security groups to limit access to your file systems. A *security group* acts as a virtual firewall to control the traffic for its associated resources. In this case, the associated resource is your file system's network interface. You also use VPC security groups to control network traffic for your Lustre clients. 

### EFA-enabled security groups
<a name="efa-security-groups"></a>

If you are going to create an EFA-enabled FSx for Lustre, you should first create an EFA-enabled security group and specify it as the security group for the file system. An EFA requires a security group that allows all inbound and outbound traffic to and from the security group itself and the security group of the clients if clients reside in a different security group. For more information, see [Step 1: Prepare an EFA-enabled security group](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/efa-start.html#efa-start-security) in the *Amazon EC2 User Guide*.

### Controlling Access Using Inbound and Outbound Rules
<a name="inbound-outbound-rules"></a>

To use a security group to control access to your Amazon FSx file system and Lustre clients, you add the inbound rules to control incoming traffic and outbound rules to control the outgoing traffic from your file system and Lustre clients. Make sure to have the right network traffic rules in your security group to map your Amazon FSx file system's file share to a folder on your supported compute instance. 

For more information on security group rules, see [Security Group Rules](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-security-groups.html#security-group-rules) in the *Amazon EC2 User Guide*. <a name="create-security-group"></a>

**To create a security group for your Amazon FSx file system**

1. Open the Amazon EC2 console at [https://console.aws.amazon.com/ec2](https://console.aws.amazon.com/ec2).

1. In the navigation pane, choose **Security Groups**.

1. Choose **Create Security Group**.

1. Specify a name and description for the security group.

1. For **VPC**, choose the VPC associated with your Amazon FSx file system to create the security group within that VPC.

1.  Choose **Create** to create the security group. 

Next, you add inbound rules to the security group that you just created to enable Lustre traffic between your FSx for Lustre file servers.

**To add inbound rules to your security group**

1. Select the security group you just created if it's not already selected. For **Actions**, choose **Edit inbound rules**.

1. Add the following inbound rules.    
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/fsx/latest/LustreGuide/limit-access-security-groups.html)

1. Choose **Save** to save and apply the new inbound rules.

By default, security group rules allow all outbound traffic (All, 0.0.0.0/0). If your security group doesn't allow all outbound traffic, add the following outbound rules to your security group. These rules allow traffic between FSx for Lustre file servers and Lustre clients, and between Lustre file servers.

**To add outbound rules to your security group**

1.  Choose the same security group to which you just added the inbound rules. For **Actions**, choose **Edit outbound rules**. 

1. Add the following outbound rules.    
[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/fsx/latest/LustreGuide/limit-access-security-groups.html)

1. Choose **Save** to save and apply the new outbound rules.

**To associate a security group with your Amazon FSx file system**

1. Open the Amazon FSx console at [https://console.aws.amazon.com/fsx/](https://console.aws.amazon.com/fsx/).

1. On the console dashboard, choose your file system to view its details.

1. On the **Network & Security** tab, click on the **Amazon EC2 console** link under **Network Interface(s)** to view all network interfaces for your file system.

1. For each network interface, choose **Actions**, then choose **Change security groups**.

1. In the **Change security groups** dialog box, choose the security groups that you want to associate with the network interface.

1. Choose **Save**.

## Lustre client VPC security group rules
<a name="lustre-client-inbound-outbound-rules"></a>

You use VPC security groups to control access to your Lustre clients by adding inbound rules to control incoming traffic and outbound rules to control the outgoing traffic from your Lustre clients. Make sure to have the right network traffic rules in your security group to ensure that Lustre traffic can flow between your Lustre clients and your Amazon FSx file systems.

Add the following inbound rules to the security groups applied to your Lustre clients.


| Type | Protocol | Port Range | Source | Description | 
| --- | --- | --- | --- | --- | 
| Custom TCP rule | TCP | 988 | Choose Custom and enter the security group IDs of the security groups that are applied to your Lustre clients | Allows Lustre traffic between Lustre clients | 
| Custom TCP rule | TCP | 988 | Choose Custom and enter the security group IDs of the security groups associated with your FSx for Lustre file systems  | Allows Lustre traffic between FSx for Lustre file servers and Lustre clients | 
| Custom TCP rule | TCP | 1018-1023 | Choose Custom and enter the security group IDs of the security groups that are applied to your Lustre clients | Allows Lustre traffic between Lustre clients | 
| Custom TCP rule | TCP | 1018-1023 | Choose Custom and enter the security group IDs of the security groups associated with your FSx for Lustre file systems  | Allows Lustre traffic between FSx for Lustre file servers and Lustre clients | 

Add the following outbound rules to the security groups applied to your Lustre clients.


| Type | Protocol | Port Range | Source | Description | 
| --- | --- | --- | --- | --- | 
| Custom TCP rule | TCP | 988 | Choose Custom and enter the security group IDs of the security groups that are applied to your Lustre clients | Allows Lustre traffic between Lustre clients | 
| Custom TCP rule | TCP | 988 | Choose Custom and enter the security group IDs of the security groups associated with your FSx for Lustre file systems | Allow Lustre traffic between FSx for Lustre file servers and Lustre clients | 
| Custom TCP rule | TCP | 1018-1023 | Choose Custom and enter the security group IDs of the security groups that are applied to your Lustre clients | Allows Lustre traffic between Lustre clients | 
| Custom TCP rule | TCP | 1018-1023 | Choose Custom and enter the security group IDs of the security groups associated with your FSx for Lustre file systems | Allows Lustre traffic between FSx for Lustre file servers and Lustre clients | 

# Amazon VPC network ACLs
<a name="limit-access-acl"></a>

Another option for securing access to the file system within your VPC is to establish network access control lists (network ACLs). Network ACLs are separate from security groups, but have similar functionality to add an additional layer of security to the resources in your VPC. For more information on implementing access control using network ACLs, see [Control traffic to subnets using Network ACLs](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-network-acls.html) in the *Amazon VPC User Guide*. 

# Compliance Validation for Amazon FSx for Lustre
<a name="fsx-lustre-compliance"></a>

To learn whether an AWS service is within the scope of specific compliance programs, see [AWS services in Scope by Compliance Program](https://aws.amazon.com/compliance/services-in-scope/) and choose the compliance program that you are interested in. For general information, see [AWS Compliance Programs](https://aws.amazon.com/compliance/programs/).

You can download third-party audit reports using AWS Artifact. For more information, see [Downloading Reports in AWS Artifact](https://docs.aws.amazon.com/artifact/latest/ug/downloading-documents.html).

Your compliance responsibility when using AWS services is determined by the sensitivity of your data, your company's compliance objectives, and applicable laws and regulations. For more information about your compliance responsibility when using AWS services, see [AWS Security Documentation](https://docs.aws.amazon.com/security/).

# Amazon FSx for Lustre and interface VPC endpoints (AWS PrivateLink)
<a name="fsx-vpc-endpoints"></a>

You can improve the security posture of your VPC by configuring Amazon FSx to use an interface VPC endpoint. Interface VPC endpoints are powered by [AWS PrivateLink](https://aws.amazon.com/privatelink), a technology that enables you to privately access Amazon FSx APIs without an internet gateway, NAT device, VPN connection, or Direct Connect connection. Instances in your VPC don't need public IP addresses to communicate with Amazon FSx APIs. Traffic between your VPC and Amazon FSx does not leave the AWS network.

Each interface VPC endpoint is represented by one or more elastic network interfaces in your subnets. A network interface provides a private IP address that serves as an entry point for traffic to the Amazon FSx API.



## Considerations for Amazon FSx interface VPC endpoints
<a name="privatelink-considerations"></a>

Before you set up an interface VPC endpoint for Amazon FSx, be sure to review [ Interface VPC endpoint properties and limitations](https://docs.aws.amazon.com/vpc/latest/privatelink/vpce-interface.html#vpce-interface-limitations) in the *Amazon VPC User Guide*.

You can call any of the Amazon FSx API operations from your VPC. For example, you can create an FSx for Lustre file system by calling the CreateFileSystem API from within your VPC. For the full list of Amazon FSx APIs, see [Actions](https://docs.aws.amazon.com/fsx/latest/APIReference/API_Operations.html) in the Amazon FSx API Reference.

### VPC peering considerations
<a name="privatelink-vpc-peering"></a>

You can connect other VPCs to the VPC with interface VPC endpoints using VPC peering. VPC peering is a networking connection between two VPCs. You can establish a VPC peering connection between your own two VPCs, or with a VPC in another AWS account. The VPCs can also be in two different AWS Regions.

Traffic between peered VPCs stays on the AWS network and does not traverse the public internet. Once VPCs are peered, resources like Amazon Elastic Compute Cloud (Amazon EC2) instances in both VPCs can access the Amazon FSx API through interface VPC endpoints created in the one of the VPCs.

## Creating an interface VPC endpoint for Amazon FSx API
<a name="create-vpce-fsx"></a>

You can create a VPC endpoint for the Amazon FSx API using either the Amazon VPC console or the AWS Command Line Interface (AWS CLI). For more information, see [ Creating an interface VPC endpoint](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#create-interface-endpoint) in the *Amazon VPC User Guide*.

For a complete list of Amazon FSx endpoints, see [Amazon FSx endpoints and quotas](https://docs.aws.amazon.com/general/latest/gr/fsxn.html) in the *Amazon Web Services General Reference*. 

To create an interface VPC endpoint for Amazon FSx, use one of the following:
+ `com.amazonaws.region.fsx` – Creates an endpoint for Amazon FSx API operations.
+ **`com.amazonaws.region.fsx-fips`** – Creates an endpoint for the Amazon FSx API that complies with [Federal Information Processing Standard (FIPS) 140-2](https://aws.amazon.com/compliance/fips/).

To use the private DNS option, you must set the `enableDnsHostnames` and `enableDnsSupport` attributes of your VPC. For more information, see [ Viewing and updating DNS support for your VPC](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-dns.html#vpc-dns-updating) in the *Amazon VPC User Guide*.

Excluding AWS Regions in China, if you enable private DNS for the endpoint, you can make API requests to Amazon FSx with the VPC endpoint using its default DNS name for the AWS Region, for example `fsx.us-east-1.amazonaws.com`. For the China (Beijing) and China (Ningxia) AWS Regions, you can make API requests with the VPC endpoint using `fsx-api---cn-north-1.amazonaws.com.rproxy.govskope.ca.cn` and `fsx-api---cn-northwest-1.amazonaws.com.rproxy.govskope.ca.cn`, respectively.

For more information, see [ Accessing a service through an interface VPC endpoint](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#access-service-though-endpoint) in the *Amazon VPC User Guide*.

## Creating a VPC endpoint policy for Amazon FSx
<a name="create-vpce-policy-fsx"></a>

To further control access to the Amazon FSx API, you can optionally attach an AWS Identity and Access Management (IAM) policy to your VPC endpoint. The policy specifies the following:
+ The principal that can perform actions.
+ The actions that can be performed.
+ The resources on which actions can be performed. 

For more information, see [Controlling access to services with VPC endpoints](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-endpoints-access.html) in the *Amazon VPC User Guide*.
