# Security in Timestream for LiveAnalytics
<a name="security"></a>

Cloud security at AWS is the highest priority. As an AWS customer, you benefit from a data center and network architecture that is 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 AWS Cloud. AWS also provides you with services that you can use securely. The effectiveness of our security is regularly tested and verified by third-party auditors as part of the [AWS compliance programs](https://aws.amazon.com/compliance/programs/). To learn about the compliance programs that apply to Timestream for LiveAnalytics, 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 organization's requirements, and applicable laws and regulations. 

This documentation will help you understand how to apply the shared responsibility model when using Timestream for LiveAnalytics. The following topics show you how to configure Timestream for LiveAnalytics to meet your security and compliance objectives. You'll also learn how to use other AWS services that can help you to monitor and secure your Timestream for LiveAnalytics resources.

# Data protection in Timestream for LiveAnalytics
<a name="data-protection"></a>

The AWS [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/) applies to data protection in Amazon Timestream Live Analytics. 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 Timestream Live Analytics 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.

**Topics**
+ [Encryption at rest](EncryptionAtRest.md)
+ [Encryption in transit](EncryptionInTransit.md)
+ [Key management](KeyManagement.md)

# Encryption at rest
<a name="EncryptionAtRest"></a>

Timestream for LiveAnalytics encryption at rest provides enhanced security by encrypting all your data at rest using encryption keys stored in [AWS Key Management Service (AWS KMS)](https://aws.amazon.com/kms/). This functionality helps reduce the operational burden and complexity involved in protecting sensitive data. With encryption at rest, you can build security-sensitive applications that meet strict encryption compliance and regulatory requirements. 
+ Encryption is turned on by default on your Timestream for LiveAnalytics database, and cannot be turned off. The industry standard AES-256 encryption algorithm is the default encryption algorithm used.
+ AWS KMS is required for encryption at rest in Timestream for LiveAnalytics.
+ You cannot encrypt only a subset of items in a table.
+  You don't need to modify your database client applications to use encryption. 

 If you do not provide a key, Timestream for LiveAnalytics creates and uses an AWS KMS key named `alias/aws/timestream` in your account. 

You may use your own customer managed key in KMS to encrypt your Timestream for LiveAnalytics data. For more information on keys in Timestream for LiveAnalytics, see [Key management](KeyManagement.md). 

 Timestream for LiveAnalytics stores your data in two storage tiers, memory store and magnetic store. Memory store data is encrypted using a Timestream for LiveAnalytics service key. Magnetic store data is encrypted using your AWS KMS key. 

The Timestream Query service requires credentials to access your data. These credentials are encrypted using your KMS key.

**Note**  
Timestream for LiveAnalytics doesn't call AWS KMS for every Decrypt operation. Instead, it maintains a local cache of keys for 5 minutes with active traffic. Any permission changes are propagated through the Timestream for LiveAnalytics system with eventual consistency within at most 5 minutes.

# Encryption in transit
<a name="EncryptionInTransit"></a>

All your Timestream Live Analytics data is encrypted in transit. By default, all communications to and from Timestream for LiveAnalytics are protected by using Transport Layer Security (TLS) encryption. 

# Key management
<a name="KeyManagement"></a>

 You can manage keys for Amazon Timestream Live Analytics using the [AWS Key Management Service (AWS KMS)](https://docs.aws.amazon.com/kms/latest/developerguide/). **Timestream Live Analytics requires the use of KMS to encrypt your data.** You have the following options for key management, depending on how much control you require over your keys: 

**Database and table resources**
+  *Timestream Live Analytics-managed key: * If you do not provide a key, Timestream Live Analytics will create a `alias/aws/timestream` key using KMS. 
+  *Customer managed key: * KMS customer managed keys are supported. Choose this option if you require more control over the permissions and lifecycle of your keys, including the ability to have them automatically rotated on an annual basis.

**Scheduled query resource**
+  *Timestream Live Analytics-owned key: * If you do not provide a key, Timestream Live Analytics will use its own a KMS key to encrypt the Query resource, this key is present in timestream account. See [AWS owned keys](https://docs.aws.amazon.com/kms/latest/developerguide/concepts.html#aws-owned-cmk) in the KMS developer guide for more details.
+  *Customer managed key: * KMS customer managed keys are supported. Choose this option if you require more control over the permissions and lifecycle of your keys, including the ability to have them automatically rotated on an annual basis.

KMS keys in an external key store (XKS) are not supported.

# Identity and access management for Amazon Timestream for LiveAnalytics
<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 Timestream for LiveAnalytics resources. IAM is an AWS service that you can use with no additional charge.

**Topics**
+ [Audience](#security_iam_audience)
+ [Authenticating with identities](#security_iam_authentication)
+ [Managing access using policies](#security_iam_access-manage)
+ [How Amazon Timestream for LiveAnalytics works with IAM](security_iam_service-with-iam.md)
+ [AWS managed policies for Amazon Timestream Live Analytics](security-iam-awsmanpol.md)
+ [Amazon Timestream for LiveAnalytics identity-based policy examples](security_iam_id-based-policy-examples.md)
+ [Troubleshooting Amazon Timestream for LiveAnalytics identity and access](security_iam_troubleshoot.md)

## 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 Timestream for LiveAnalytics identity and access](security_iam_troubleshoot.md))
+ **Service administrator** - determine user access and submit permission requests (see [How Amazon Timestream for LiveAnalytics works with IAM](security_iam_service-with-iam.md))
+ **IAM administrator** - write policies to manage access (see [Amazon Timestream for LiveAnalytics identity-based policy examples](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*.

### 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.

### Access control lists (ACLs)
<a name="security_iam_access-manage-acl"></a>

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.

Amazon S3, AWS WAF, and Amazon VPC are examples of services that support ACLs. To learn more about ACLs, see [Access control list (ACL) overview](https://docs.aws.amazon.com/AmazonS3/latest/userguide/acl-overview.html) in the *Amazon Simple Storage Service Developer Guide*.

### 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*.

# How Amazon Timestream for LiveAnalytics works with IAM
<a name="security_iam_service-with-iam"></a>

Before you use IAM to manage access to Timestream for LiveAnalytics, you should understand what IAM features are available to use with Timestream for LiveAnalytics. To get a high-level view of how Timestream for LiveAnalytics and other AWS services work with IAM, see [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*.

+ [Timestream for LiveAnalytics IAM roles](#security_iam_service-with-iam-roles)

## Timestream for LiveAnalytics identity-based policies
<a name="security_iam_service-with-iam-id-based-policies"></a>

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. Timestream for LiveAnalytics supports specific actions and resources, and condition keys. To learn about all of the elements that you 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*.

### Actions
<a name="security_iam_service-with-iam-id-based-policies-actions"></a>

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.

 You can specify the following actions in the Action element of an IAM policy statement. Use policies to grant permissions to perform an operation in AWS. When you use an action in a policy, you usually allow or deny access to the API operation, CLI command or SQL command with the same name. 

 In some cases, a single action controls access to an API operation as well as SQL command. Alternatively, some operations require several different actions. 

For a list of supported Timestream for LiveAnalytics `Action`'s, see the table below:

**Note**  
For all database-specific `Actions`, you can specify a database ARN to limit the action to a particular database.


| Actions | Description | Access level | Resource types (\$1required) | 
| --- | --- | --- | --- | 
|  DescribeEndpoints  |  Returns the Timestream endpoint that subsequent requests must be made to.   |  All  |  \$1  | 
|  Select  |  Run queries on Timestream that select data from one or more tables. [See this note for a detailed explanation](#security_iam_service-with-iam-id-based-policies-actions.select-vs-selectvalues)  |  Read  |  table\$1  | 
|  CancelQuery  |  Cancel a query.  |  Read  |  \$1  | 
|  ListTables  |  Get the list of tables.  |  List  |  database\$1  | 
|  ListDatabases  |  Get the list of databases.  |  List  |  \$1  | 
|  ListMeasures  |  Get the list of measures.  |  Read  |  table\$1  | 
|  DescribeTable  |  Get the table description.  |  Read  |  table\$1  | 
|  DescribeDatabase  |  Get the database description.  |  Read  |  database\$1  | 
|  SelectValues  |  Run queries that do not require a particular resource to be specified. [See this note for a detailed explanation](#security_iam_service-with-iam-id-based-policies-actions.select-vs-selectvalues).  |  Read  |  \$1  | 
|  WriteRecords  |  Insert data into Timestream.  |  Write  |  table\$1  | 
|  CreateTable  |  Create a table.  |  Write  |  database\$1  | 
|  CreateDatabase  |  Create a database.  |  Write  |  \$1  | 
|  DeleteDatabase  |  Delete a database.  |  Write  |  \$1  | 
|  UpdateDatabase  |  Update a database.  |  Write  |  \$1  | 
|  DeleteTable  |  Delete a table.  |  Write  |  database\$1  | 
|  UpdateTable  |  Update a table.   |  Write  |  database\$1  | 

#### SelectValues vs. select:
<a name="security_iam_service-with-iam-id-based-policies-actions.select-vs-selectvalues"></a>

`SelectValues` is an `Action` that is used for queries that *do not* require a resource. An example of a query that does not require a resource is as follows:

```
SELECT 1
```

Notice that this query does not refer to a particular Timestream for LiveAnalytics resource. Consider another example:

```
SELECT now()
```

This query returns the current timestamp using the `now()` function, but does not require a resource to be specified. `SelectValues` is often used for testing, so that Timestream for LiveAnalytics can run queries without resources. Now, consider a `Select` query:

```
SELECT * FROM database.table
```

This type of query requires a resource, specifcially an Timestream for LiveAnalytics `table` , so that the specified data can be fetched from the table.

### Resources
<a name="security_iam_service-with-iam-id-based-policies-resources"></a>

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": "*"
```

In Timestream for LiveAnalytics databases and tables can be used in the `Resource` element of IAM permissions.

The Timestream for LiveAnalytics database resource has the following ARN:

```
arn:${Partition}:timestream:${Region}:${Account}:database/${DatabaseName}
```

The Timestream for LiveAnalytics table resource has the following ARN:

```
arn:${Partition}:timestream:${Region}:${Account}:database/${DatabaseName}/table/${TableName}
```

For more information about the format of ARNs, see [Amazon Resource Names (ARNs) and AWS Service Namespaces](https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html).

For example, to specify the `database` keyspace in your statement, use the following ARN:

```
"Resource": "arn:aws:timestream:us-east-1:123456789012:database/mydatabase"
```

To specify all databases that belong to a specific account, use the wildcard (\$1):

```
"Resource": "arn:aws:timestream:us-east-1:123456789012:database/*"
```

Some Timestream for LiveAnalytics actions, such as those for creating resources, cannot be performed on a specific resource. In those cases, you must use the wildcard (\$1).

```
"Resource": "*"
```

### Condition keys
<a name="security_iam_service-with-iam-id-based-policies-conditionkeys"></a>

Timestream for LiveAnalytics does not provide any service-specific condition keys, but it does support using some global condition keys. 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*.

### Examples

## Timestream for LiveAnalytics resource-based policies
<a name="security_iam_service-with-iam-resource-based-policies"></a>

Timestream for LiveAnalytics does not support resource-based policies. To view an example of a detailed resource-based policy page, see [https://docs.aws.amazon.com/lambda/latest/dg/access-control-resource-based.html](https://docs.aws.amazon.com/lambda/latest/dg/access-control-resource-based.html).

## Authorization based on Timestream for LiveAnalytics tags
<a name="security_iam_service-with-iam-tags"></a>

You can manage access to your Timestream for LiveAnalytics resources by using tags. To manage resource 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 `timestream:ResourceTag/key-name`, `aws:RequestTag/key-name`, or `aws:TagKeys` condition keys. For more information about tagging Timestream for LiveAnalytics resources, see [Adding tags and labels to resources](tagging-keyspaces.md).

To view example identity-based policies for limiting access to a resource based on the tags on that resource, see [Timestream for LiveAnalytics resource access based on tags](security_iam_id-based-policy-examples.md#security_iam_id-based-policy-examples-tags).

## Timestream for LiveAnalytics IAM roles
<a name="security_iam_service-with-iam-roles"></a>

An [IAM role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html) is an entity within your AWS account that has specific permissions.

### Using temporary credentials with Timestream for LiveAnalytics
<a name="security_iam_service-with-iam-roles-tempcreds"></a>

You can use temporary credentials to sign in with federation, assume an IAM role, or to assume a cross-account role. You obtain temporary security credentials by calling AWS STS API operations such as [AssumeRole](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html) or [GetFederationToken](https://docs.aws.amazon.com/STS/latest/APIReference/API_GetFederationToken.html). 

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

Timestream for LiveAnalytics does not support service-linked roles.

### Service roles
<a name="security_iam_service-with-iam-roles-service"></a>

Timestream for LiveAnalytics does not support service roles.

# AWS managed policies for Amazon Timestream Live Analytics
<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*.

# Amazon Timestream for LiveAnalytics identity-based policy examples
<a name="security_iam_id-based-policy-examples"></a>

By default, IAM users and roles don't have permission to create or modify Timestream for LiveAnalytics resources. They also can't perform tasks using the AWS Management Console, CQLSH, AWS CLI, or AWS API. An IAM administrator must create IAM policies that grant users and roles permission to perform specific API operations on the specified resources they need. The administrator must then attach those policies to the IAM users or groups that require those permissions.

To learn how to create an IAM identity-based policy using these example JSON policy documents, see [Creating Policies on the JSON Tab](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create.html#access_policies_create-json-editor) in the *IAM User Guide*.

**Topics**
+ [Policy best practices](#security_iam_service-with-iam-policy-best-practices)
+ [Using the Timestream for LiveAnalytics console](#security_iam_id-based-policy-examples-console)
+ [Allow users to view their own permissions](#security_iam_id-based-policy-examples-view-own-permissions)

+ [Timestream for LiveAnalytics resource access based on tags](#security_iam_id-based-policy-examples-tags)
+ [Scheduled queries](#security_iam_id-based-policy-examples-sheduledqueries)

## 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 Timestream for LiveAnalytics 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 Timestream for LiveAnalytics console
<a name="security_iam_id-based-policy-examples-console"></a>

Timestream for LiveAnalytics does not require specific permissions to access the Amazon Timestream for LiveAnalytics console. You need at least read-only permissions to list and view details about the Timestream for LiveAnalytics 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 (IAM users or roles) with that policy.

## 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.

## Timestream for LiveAnalytics resource access based on tags
<a name="security_iam_id-based-policy-examples-tags"></a>

You can use conditions in your identity-based policy to control access to Timestream for LiveAnalytics resources based on tags. This section provides some examples. 

The following example shows how you can create a policy that grants permissions to a user to view a table if the table's `Owner` contains the value of that user's user name.

------
#### [ JSON ]

****  

```
{
    "Version":"2012-10-17",		 	 	 
    "Statement": [
        {
            "Sid": "ReadOnlyAccessTaggedTables",
            "Effect": "Allow",
            "Action": "timestream:Select",
            "Resource": "arn:aws:timestream:us-east-2:111122223333:database/mydatabase/table/*",
            "Condition": {
                "StringEquals": {
                    "aws:ResourceTag/Owner": "${aws:username}"
                }
            }
        }
    ]
}
```

------

You can attach this policy to the IAM users in your account. If a user named `richard-roe` attempts to view an Timestream for LiveAnalytics table, the table must be tagged `Owner=richard-roe` or `owner=richard-roe`. Otherwise, he is denied access. The condition tag key `Owner` matches both `Owner` and `owner` because condition key names are not case-sensitive. 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*.

The following policy grants permissions to a user to create tables with tags if the tag passed in request has a key `Owner` and a value `username`:

------
#### [ JSON ]

****  

```
{
    "Version":"2012-10-17",

            "Action": [
                "timestream:CreateTable",

            }

            "Action": [
                "timestream:TagResource"
            ],
            "Resource": "*",
            "Condition": {
                "StringEquals": {
                    "aws:RequestTag/env": [
                        "test",
                        "dev"

                }
            }
        }

# Troubleshooting Amazon Timestream for LiveAnalytics 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 Timestream for LiveAnalytics and IAM.

**Topics**
+ [I am not authorized to perform an action in Timestream for LiveAnalytics](#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 Timestream for LiveAnalytics resources](#security_iam_troubleshoot-cross-account-access)

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

If the AWS Management Console tells you that you're not authorized to perform an action, then you must contact your administrator for assistance. Your administrator is the person that provided you with your sign-in credentials.

The following example error occurs when the `mateojackson` IAM user tries to use the console to view details about a *table* but does not have `timestream:Select` permissions for the table.

```
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: timestream:Select on resource: mytable
```

In this case, Mateo asks his administrator to update his policies to allow him to access the `mytable` resource using the `timestream:Select` action.

## 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 Timestream for LiveAnalytics.

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 Timestream for LiveAnalytics. 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 Timestream for LiveAnalytics 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 Timestream for LiveAnalytics supports these features, see [How Amazon Timestream for LiveAnalytics 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*.
+ To learn how to provide access to your resources to third-party AWS accounts, see [Providing access to AWS accounts owned by third parties](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_common-scenarios_third-party.html) in the *IAM User Guide*.

# Logging and monitoring in Timestream for LiveAnalytics
<a name="monitoring"></a>

Monitoring is an important part of maintaining the reliability, availability, and performance of Timestream for LiveAnalytics and your AWS solutions. You should collect monitoring data from all of the parts of your AWS solution so that you can more easily debug a multi-point failure if one occurs. However, before you start monitoring Timestream for LiveAnalytics, you should create a monitoring plan that includes answers to the following questions:
+ What are your monitoring goals?
+ What resources will you monitor?
+ How often will you monitor these resources?
+ What monitoring tools will you use?
+ Who will perform the monitoring tasks?
+ Who should be notified when something goes wrong?

The next step is to establish a baseline for normal Timestream for LiveAnalytics performance in your environment, by measuring performance at various times and under different load conditions. As you monitor Timestream for LiveAnalytics, store historical monitoring data so that you can compare it with current performance data, identify normal performance patterns and performance anomalies, and devise methods to address issues.

To establish a baseline, you should, at a minimum, monitor the following items:
+ System errors, so that you can determine whether any requests resulted in an error.

**Topics**
+ [Monitoring tools](monitoring-automated-manual.md)
+ [Logging Timestream for LiveAnalytics API calls with AWS CloudTrail](logging-using-cloudtrail.md)

# Monitoring tools
<a name="monitoring-automated-manual"></a>

AWS provides various tools that you can use to monitor Timestream for LiveAnalytics. You can configure some of these tools to do the monitoring for you, while some of the tools require manual intervention. We recommend that you automate monitoring tasks as much as possible.

**Topics**

## Automated monitoring tools
<a name="monitoring-automated_tools"></a>

You can use the following automated monitoring tools to watch Timestream for LiveAnalytics and report when something is wrong:
+ **Amazon CloudWatch Alarms** – Watch a single metric over a time period that you specify, and perform one or more actions based on the value of the metric relative to a given threshold over a number of time periods. The action is a notification sent to an Amazon Simple Notification Service (Amazon SNS) topic or Amazon EC2 Auto Scaling policy. CloudWatch alarms do not invoke actions simply because they are in a particular state; the state must have changed and been maintained for a specified number of periods. For more information, see [Monitoring with Amazon CloudWatch](monitoring-cloudwatch.md).

## Manual monitoring tools
<a name="monitoring-manual-tools"></a>

Another important part of monitoring Timestream for LiveAnalytics involves manually monitoring those items that the CloudWatch alarms don't cover. The Timestream for LiveAnalytics, CloudWatch, Trusted Advisor, and other AWS Management Console dashboards provide an at-a-glance view of the state of your AWS environment.
+ The CloudWatch home page shows the following:
  + Current alarms and status
  + Graphs of alarms and resources
  + Service health status

  In addition, you can use CloudWatch to do the following: 
  + Create [customized dashboards](https://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/CloudWatch_Dashboards.html) to monitor the services you care about
  + Graph metric data to troubleshoot issues and discover trends
  + Search and browse all your AWS resource metrics
  + Create and edit alarms to be notified of problems

# Logging Timestream for LiveAnalytics API calls with AWS CloudTrail
<a name="logging-using-cloudtrail"></a>



Timestream for LiveAnalytics is integrated with AWS CloudTrail, a service that provides a record of actions taken by a user, role, or an AWS service in Timestream for LiveAnalytics. CloudTrail captures Data Definition Language (DDL) API calls for Timestream for LiveAnalytics as events. The calls that are captured include calls from the Timestream for LiveAnalytics console and code calls to the Timestream for LiveAnalytics API operations. If you create a trail, you can enable continuous delivery of CloudTrail events to an Amazon Simple Storage Service (Amazon S3) bucket, including events for Timestream for LiveAnalytics. If you don't configure a trail, you can still view the most recent events on the CloudTrail console in **Event history**. Using the information collected by CloudTrail, you can determine the request that was made to Timestream for LiveAnalytics, the IP address from which the request was made, who made the request, when it was made, and additional details. 

To learn more about CloudTrail, see the [AWS CloudTrail User Guide](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/).

## Timestream for LiveAnalytics information in CloudTrail
<a name="service-name-info-in-cloudtrail"></a>

CloudTrail is enabled on your AWS account when you create the account. When activity occurs in Timestream for LiveAnalytics, that activity is recorded in a CloudTrail event along with other AWS service events in **Event history**. You can view, search, and download recent events in your AWS account. For more information, see [Viewing Events with CloudTrail Event History](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/view-cloudtrail-events.html). 

**Warning**  
Currently, Timestream for LiveAnalytics generates CloudTrail events for all management and `Query` API operations, but does not generate events for `WriteRecords` and `DescribeEndpoints` APIs. 

For an ongoing record of events in your AWS account, including events for Timestream for LiveAnalytics, create a trail. A *trail* enables CloudTrail to deliver log files to an Amazon S3 bucket. By default, when you create a trail in the console, the trail applies to all AWS Regions. The trail logs events from all Regions in the AWS partition and delivers the log files to the Amazon S3 bucket that you specify. Additionally, you can configure other AWS services to further analyze and act upon the event data collected in CloudTrail logs.

For more information, see the following topics in the *AWS CloudTrail User Guide*: 
+ [Overview for Creating a Trail](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-create-and-update-a-trail.html)
+ [CloudTrail Supported Services and Integrations](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-aws-service-specific-topics.html#cloudtrail-aws-service-specific-topics-integrations)
+ [Configuring Amazon SNS Notifications for CloudTrail](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/getting_notifications_top_level.html)
+ [Receiving CloudTrail Log Files from Multiple Regions](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/receive-cloudtrail-log-files-from-multiple-regions.html)
+ [Receiving CloudTrail Log Files from Multiple Accounts](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-receive-logs-from-multiple-accounts.html)
+ [Logging data events](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/logging-data-events-with-cloudtrail.html)

Every event or log entry contains information about who generated the request. The identity information helps you determine the following: 
+ Whether the request was made with root or AWS Identity and Access Management (IAM) user credentials
+ Whether the request was made with temporary security credentials for a role or federated user
+ Whether the request was made by another AWS service

For more information, see the [CloudTrail userIdentity Element](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-event-reference-user-identity.html).

For `Query` API events:
+ Create a trail that receives all events or select events with Timestream for LiveAnalytics resource type `AWS::Timestream::Database` or `AWS::Timestream::Table`.
+ `Query` API requests that do not access any database or table or that result in a validation exception due to a malformed query string are recorded in CloudTrail with a resource type `AWS::Timestream::Database` and an ARN value of:

  ```
  arn:aws:timestream:(region):(accountId):database/NO_RESOURCE_ACCESSED
  ```

  These events are delivered only to trails that receive events with resource type `AWS::Timestream::Database`.

# Resilience in Amazon Timestream Live Analytics
<a name="disaster-recovery-resiliency"></a>

The AWS global infrastructure is built around AWS Regions and Availability Zones. AWS Regions provide multiple physically separated and isolated Availability Zones, which are connected with low-latency, high-throughput, and highly redundant networking. With Availability Zones, you can design and operate applications and databases that automatically fail over between zones without interruption. Availability Zones are more highly available, fault tolerant, and scalable than traditional single or multiple data center infrastructures. 

For more information about AWS Regions and Availability Zones, see [AWS Global Infrastructure](https://aws.amazon.com/about-aws/global-infrastructure/).

For information about data protection functionality for Timestream available through AWS Backup, see [Working with AWS Backup](backups.md).

# Infrastructure security in Amazon Timestream Live Analytics
<a name="infrastructure-security"></a>

As a managed service, Amazon Timestream Live Analytics is protected by the AWS global network security procedures that are described in the [Amazon Web Services: Overview of Security Processes](https://d0.awsstatic.com/whitepapers/Security/AWS_Security_Whitepaper.pdf) whitepaper.

You use AWS published API calls to access Timestream Live Analytics through the network. Clients must support Transport Layer Security (TLS) 1.0 or later. We recommend TLS 1.2 or later. Clients must also support cipher suites with perfect forward secrecy (PFS) such as Ephemeral Diffie-Hellman (DHE) or Elliptic Curve Ephemeral Diffie-Hellman (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](https://docs.aws.amazon.com/STS/latest/APIReference/Welcome.html) (AWS STS) to generate temporary security credentials to sign requests.

Timestream Live Analytics is architected so that your traffic is isolated to the specific AWS Region that your Timestream Live Analytics instance resides in.

# Configuration and vulnerability analysis in Timestream
<a name="ConfigAndVulnerability"></a>

 Configuration and IT controls are a shared responsibility between AWS and you, our customer. For more information, see the AWS [shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/). In addition to the shared responsibility model, Timestream for LiveAnalytics users should be aware of the following: 
+ It is the customer responsibility to patch their client applications with the relevant client side dependencies.
+ Customers should consider penetration testing if appropriate (see [https://aws.amazon.com/security/penetration-testing/](https://aws.amazon.com/security/penetration-testing/).)

# VPC endpoints (AWS PrivateLink)
<a name="VPCEndpoints"></a>

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

Each interface endpoint is represented by one or more [Elastic Network Interfaces](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html) in your subnets. For more information on Interface VPC endpoints, see [Interface VPC endpoints (AWS PrivateLink)](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html) in the *Amazon VPC User Guide*.

To get started with Timestream for LiveAnalytics and VPC endpoints, we've provided information on specific considerations for Timestream for LiveAnalytics with VPC endpoints, creating an interface VPC endpoint for Timestream for LiveAnalytics, creating a VPC endpoint policy for Timestream for LiveAnalytics, and using the Timestream client (for either the Write or Query SDK) with VPC endpoints..

**Topics**
+ [How VPC endpoints work with Timestream](VPCEndpoints.vpc-endpoint-considerations.md)

+ [Creating a VPC endpoint policy for Timestream for LiveAnalytics](VPCEndpoints.vpc-endpoint-policy.md)

# How VPC endpoints work with Timestream
<a name="VPCEndpoints.vpc-endpoint-considerations"></a>

 When you create a VPC endpoint to access either the Timestream Write or Timestream Query SDK, all requests are routed to endpoints within the Amazon network and do not access the public internet. More specifically, your requests are routed to the write and query endpoints of the cell that your account has been mapped to for a given region. To learn more about Timestream's cellular architecture and cell-specific endpoints, you can refer to [Cellular architecture](architecture.md#cells). For example, suppose that your account has been mapped to `cell1` in `us-west-2`, and you've set up VPC interface endpoints for writes (`ingest-cell1.timestream.us-west-2.amazonaws.com`) and queries (`query-cell1.timestream.us-west-2.amazonaws.com`). In this case, any write requests sent using these endpoints will stay entirely within the Amazon network and will not access the public internet. 

## Considerations for Timestream VPC endpoints
<a name="VPCEndpoints.vpc-endpoint-considerations.how-it-works"></a>

Consider the following when creating a VPC endpoint for Timestream:
+ Before you set up an interface VPC endpoint for Timestream for LiveAnalytics, ensure that you review [Interface endpoint properties and limitations](https://docs.aws.amazon.com/vpc/latest/userguide/vpce-interface.html#vpce-interface-limitations) in the *Amazon VPC User Guide*. 
+ Timestream for LiveAnalytics supports making calls to [all of its API actions](https://docs.aws.amazon.com/timestream/latest/developerguide/API_Reference.html) from your VPC. 
+ VPC endpoint policies are supported for Timestream for LiveAnalytics. By default, full access to Timestream for LiveAnalytics is allowed through the endpoint. 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*.
+ Because of Timestream's architecture, access to both Write and Query actions requires the creation of two VPC interface endpoints, one for each SDK. Additionally, you must specify a cell endpoint (you will only be able to create an endpoint for the Timestream cell that you are mapped to). Detailed information can be found in the [create an interface VPC endpoint for Timestream for LiveAnalytics](VPCEndpoints.vpc-endpoint-create.md) section of this guide. 

Now that you understand how Timestream for LiveAnalytics works with VPC endpoints, [create an interface VPC endpoint for Timestream for LiveAnalytics](VPCEndpoints.vpc-endpoint-create.md).

# Creating an interface VPC endpoint for Timestream for LiveAnalytics
<a name="VPCEndpoints.vpc-endpoint-create"></a>

You can create an [interface VPC endpoint](https://docs.aws.amazon.com/vpc/latest/privatelink/vpce-interface.html) for the Timestream for LiveAnalytics service using either the Amazon VPC console or the AWS Command Line Interface (AWS CLI). To create a VPC endpoint for Timestream, complete the Timestream-specific steps described below. 

**Note**  
Before completing the steps below, ensure that you understand [specific considerations for Timestream VPC endpoints.](VPCEndpoints.vpc-endpoint-considerations.md)

## Constructing a VPC endpoint service name using your Timestream cell
<a name="VPCEndpoints.vpc-endpoint-create.vpc-endpoint-name"></a>

 Because of Timestream's unique architecture, separate VPC interface endpoints must be created for each SDK (Write and Query). Additionally, you must specify a Timestream cell endpoint (you will only be able to create an endpoint for the Timestream cell that you are mapped to). To use Interface VPC Endpoints to directly connect to Timestream from within your VPC, complete the steps below: 

1. First, find an available Timestream cell endpoint. To find an available cell endpoint, use the [`DescribeEndpoints` action](https://docs.aws.amazon.com/timestream/latest/developerguide/API_query_DescribeEndpoints.html) (available through both the Write and Query APIs) to list the cell endpoints available in your Timestream account. See the [example](#VPCEndpoints.vpc-endpoint-create.vpc-endpoint-name.example) for further details. 

1. Once you've selected a cell endpoint to use, create a VPC interface endpoint string for either the Timestream Write or Query API:
   + *For the Write API:*

     ```
     com.amazonaws.<region>.timestream.ingest-<cell>
     ```
   + *For the Query API:*

     ```
     com.amazonaws.<region>.timestream.query-<cell>
     ```

    where *<region>* is a [valid AWS region code](https://docs.aws.amazon.com/general/latest/gr/rande.html) and *<cell>* is one of the cell endpoint addresses (such as `cell1` or `cell2`) returned in the [Endpoints object](https://docs.aws.amazon.com/timestream/latest/developerguide/API_query_DescribeEndpoints.html#API_query_DescribeEndpoints_ResponseSyntax) by the [DescribeEndpoints action](https://docs.aws.amazon.com/timestream/latest/developerguide/API_query_DescribeEndpoints.html). See the [example](#VPCEndpoints.vpc-endpoint-create.vpc-endpoint-name.example) for further details. 

1. Now that you have constructed a VPC endpoint service name, [create an interface endpoint](https://docs.aws.amazon.com/vpc/latest/privatelink/vpce-interface.html). When asked to provide a VPC endpoint service name, use the VPC endpoint service name that you constructed in Step 2.

### Example: Constructing your VPC endpoint service name
<a name="VPCEndpoints.vpc-endpoint-create.vpc-endpoint-name.example"></a>

In the following example, the `DescribeEndpoints` action is executed in the AWS CLI using the Write API in the `us-west-2` region:

```
aws timestream-write describe-endpoints --region us-west-2
```

This command will return the following output:

```
{
    "Endpoints": [
        {
            "Address": "ingest-cell1.timestream.us-west-2.amazonaws.com",
            "CachePeriodInMinutes": 1440
        }
    ]
}
```

In this case, *cell1* is the *<cell>* , and *us-west-2* is the *<region>*. So, the resulting VPC endpoint service name will look like: 

```
com.amazonaws.us-west-2.timestream.ingest-cell1
```

Now that you've created an interface VPC endpoint for Timestream for LiveAnalytics, [create a VPC endpoint policy for Timestream for LiveAnalytics](VPCEndpoints.vpc-endpoint-policy.md).

# Creating a VPC endpoint policy for Timestream for LiveAnalytics
<a name="VPCEndpoints.vpc-endpoint-policy"></a>

You can attach an endpoint policy to your VPC endpoint that controls access to Timestream for LiveAnalytics. The policy specifies the following information:
+ 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*. 

**Example: VPC endpoint policy for Timestream for LiveAnalytics actions**  
The following is an example of an endpoint policy for Timestream for LiveAnalytics. When attached to an endpoint, this policy grants access to the listed Timestream for LiveAnalytics actions (in this case, [https://docs.aws.amazon.com/timestream/latest/developerguide/API_ListDatabases.html](https://docs.aws.amazon.com/timestream/latest/developerguide/API_ListDatabases.html)) for all principals on all resources.

```
{
   "Statement":[
      {
         "Principal":"*",
         "Effect":"Allow",
         "Action":[
            "timestream:ListDatabases"
         ],
         "Resource":"*"
      }
   ]
}
```

# Security best practices for Amazon Timestream for LiveAnalytics
<a name="best-practices-security"></a>

Amazon Timestream for LiveAnalytics provides a number of security features to consider as you develop and implement your own security policies. The following best practices are general guidelines and don't represent a complete security solution. Because these best practices might not be appropriate or sufficient for your environment, treat them as helpful considerations rather than prescriptions. 

**Topics**
+ [Timestream for LiveAnalytics preventative security best practices](best-practices-security-preventative.md)

# Timestream for LiveAnalytics preventative security best practices
<a name="best-practices-security-preventative"></a>

The following best practices can help you anticipate and prevent security incidents in Timestream for LiveAnalytics.

**Encryption at rest**  
Timestream for LiveAnalytics encrypts at rest all user data stored in tables using encryption keys stored in [AWS Key Management Service (AWS KMS)](https://aws.amazon.com/kms/). This provides an additional layer of data protection by securing your data from unauthorized access to the underlying storage.  
Timestream for LiveAnalytics uses a single service default key (AWS owned CMK) for encrypting all of your tables. If this key doesn't exist, it is created for you. Service default keys can't be disabled. For more information, see [Timestream for LiveAnalytics Encryption at Rest](https://docs.aws.amazon.com/mcs/latest/devguide/EncryptionAtRest.html).

**Use IAM roles to authenticate access to Timestream for LiveAnalytics**  
For users, applications, and other AWS services to access Timestream for LiveAnalytics, they must include valid AWS credentials in their AWS API requests. You should not store AWS credentials directly in the application or EC2 instance. These are long-term credentials that are not automatically rotated, and therefore could have significant business impact if they are compromised. An IAM role enables you to obtain temporary access keys that can be used to access AWS services and resources.  
For more information, see [IAM Roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html).

**Use IAM policies for Timestream for LiveAnalytics base authorization**  
When granting permissions, you decide who is getting them, which Timestream for LiveAnalytics APIs they are getting permissions for, and the specific actions you want to allow on those resources. Implementing least privilege is key in reducing security risk and the impact that can result from errors or malicious intent.  
Attach permissions policies to IAM identities (that is, users, groups, and roles) and thereby grant permissions to perform operations on Timestream for LiveAnalytics resources.  
You can do this by using the following:  
+ [AWS managed (predefined) policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#aws-managed-policies)
+ [Customer managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_managed-vs-inline.html#customer-managed-policies)
+ [Tag-based authorization](security_iam_service-with-iam.md#security_iam_service-with-iam-tags)

**Consider client-side encryption**  
If you store sensitive or confidential data in Timestream for LiveAnalytics, you might want to encrypt that data as close as possible to its origin so that your data is protected throughout its lifecycle. Encrypting your sensitive data in transit and at rest helps ensure that your plaintext data isn't available to any third party.
