To get a high-level view of how Timestream for InfluxDB and other AWS services work with most IAM features, see AWS services that work with IAM in the IAM User Guide.
Identity-based policies for Timestream for InfluxDB
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 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 in the IAM User Guide.

Resource-based policies within Timestream for InfluxDB
Supports resource-based policies: No
Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM role trust policies and Amazon S3 bucket policies. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must specify a principal in a resource-based policy. Principals can include accounts, users, roles, federated users, or AWS services.
To enable cross-account access, you can specify an entire account or IAM entities in another account as the principal in a resource-based policy. For more information, see Cross account resource access in IAM in the IAM User Guide.
Policy actions for Timestream for InfluxDB
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 Timestream for InfluxDB actions, see Actions, resources and condition keys for Amazon Timestream for InfluxDB in the Service Authorization Reference.
Policy actions in Timestream for InfluxDB use the following prefix before the action:
timestream-influxdb
To specify multiple actions in a single statement, separate them with commas.
"Action": [ "timestream-influxdb:action1", "timestream-influxdb:action2" ]
You can specify multiple actions using wildcards (*). For example, to specify all actions that begin with the
word Describe, include the following action:
"Action": "timestream-influxdb:Describe*"
Policy resources for Timestream for InfluxDB
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). For actions that don't support resource-level permissions, use a wildcard (*) to indicate that the statement applies to all resources.
"Resource": "*"
To see a list of Timestream for InfluxDB resource types and their ARNs, see Resource types defined by Amazon Timestream for InfluxDB in the Service Authorization Reference. To learn with which actions you can specify the ARN of each resource, see Actions, resources and condition keys for Amazon Timestream for InfluxDB.
Policy condition keys for Timestream for InfluxDB
Supports service-specific policy condition keys: No
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, 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 in the
IAM User Guide.
Access control lists (ACLs) in Timestream for InfluxDB
Supports ACLs: No
Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format.
Attribute-based access control (ABAC) with Timestream for InfluxDB
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 of a policy using the aws:ResourceTag/,
key-nameaws:RequestTag/, or key-nameaws: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 in the IAM User Guide. To view a tutorial with steps for setting up ABAC, see Use attribute-based access control (ABAC) in the IAM User Guide.
Using Temporary credentials with Timestream for InfluxDB
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 and AWS services that work with IAM in the IAM User Guide.
Cross-service principal permissions for Timestream for InfluxDB
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.
Service roles for Timestream for InfluxDB
Supports service roles: No
A service role is an IAM role 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 in the IAM User Guide.
Warning
Changing the permissions for a service role might break Timestream for InfluxDB functionality. Edit service roles only when Timestream for InfluxDB provides guidance to do so.
Service-linked roles for Timestream for InfluxDB
Supports service-linked roles: Yes
A service-linked role is a type of service role that is linked to an AWS service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your AWS account and are owned by the service. An IAM administrator can view, but not edit the permissions for service-linked roles.
For details about creating or managing service-linked roles, see AWS services that work with IAM. Find
a service in the table that includes a Yes in the Service-linked role column.
Choose the Yes link to view the service-linked role documentation for that service.
