Identity and Access Management for Amazon OpenSearch Ingestion

Amazon Identity and Access Management (IAM) is an Amazon Web Service that helps an administrator securely control access to Amazon resources. IAM administrators control who can be authenticated (signed in) and authorized (have permissions) to use OpenSearch Ingestion resources. IAM is an Amazon Web Service that you can use with no additional charge.

Identity-based policies for OpenSearch Ingestion

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 Creating IAM 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. You can't specify the principal in an identity-based policy because it applies to the user or role to which it is attached. 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.

Policy actions for OpenSearch Ingestion

The Action element of a JSON policy describes the actions that you can use to allow or deny access in a policy. Policy actions usually have the same name as the associated Amazon API operation. There are some exceptions, such as permission-only actions that don't have a matching API operation. There are also some operations that require multiple actions in a policy. These additional actions are called dependent actions.

Include actions in a policy to grant permissions to perform the associated operation.

Policy actions in OpenSearch Ingestion use the following prefix before the action:

osis

To specify multiple actions in a single statement, separate them with commas.

"Action": [
      "osis:action1",
      "osis:action2"
         ]

You can specify multiple actions using wildcard characters (*). For example, to specify all actions that begin with the word List, include the following action:

"Action": "osis:List*"

To view examples of OpenSearch Ingestion identity-based policies, see Identity-based policy examples for OpenSearch Serverless.

Policy resources for OpenSearch Ingestion

Administrators can use Amazon 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. Statements must include either a Resource or a NotResource element. As a best practice, specify a resource using its Amazon Resource Name (ARN). You can do this for actions that support a specific resource type, known as resource-level permissions.

For actions that don't support resource-level permissions, such as listing operations, use a wildcard (*) to indicate that the statement applies to all resources.

"Resource": "*"

Policy condition keys for Amazon OpenSearch Ingestion

Administrators can use Amazon 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 (or Condition block) lets you specify conditions in which a statement is in effect. The Condition element is optional. 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.

If you specify multiple Condition elements in a statement, or multiple keys in a single Condition element, Amazon evaluates them using a logical AND operation. If you specify multiple values for a single condition key, Amazon evaluates the condition using a logical OR operation. All of the conditions must be met before the statement's permissions are granted.

You can also use placeholder variables when you specify conditions. For example, you can grant an IAM user permission to access a resource only if it is tagged with their IAM user name. For more information, see IAM policy elements: variables and tags in the IAM User Guide.

Amazon supports global condition keys and service-specific condition keys. To see all Amazon global condition keys, see Amazon global condition context keys in the IAM User Guide.

To see a list of OpenSearch Ingestion condition keys, see Condition keys for Amazon OpenSearch Ingestion in the Service Authorization Reference. To learn with which actions and resources you can use a condition key, see Actions defined by Amazon OpenSearch Ingestion.

ABAC with OpenSearch Ingestion

Attribute-based access control (ABAC) is an authorization strategy that defines permissions based on attributes. In Amazon, these attributes are called tags. You can attach tags to IAM entities (users or roles) and to many Amazon resources. Tagging entities and resources is the first step of ABAC. Then you design ABAC policies to allow operations when the principal's tag matches the tag on the resource that they are trying to access.

ABAC is helpful in environments that are growing rapidly and helps with situations where policy management becomes cumbersome.

To control access based on tags, you provide tag information in the condition element 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 What is ABAC? 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.

For more information about tagging OpenSearch Ingestion resources, see Tagging Amazon OpenSearch Ingestion pipelines.

Using temporary credentials with OpenSearch Ingestion

Some Amazon Web Services don't work when you sign in using temporary credentials. For additional information, including which Amazon Web Services work with temporary credentials, see Amazon Web Services that work with IAM in the IAM User Guide.

You are using temporary credentials if you sign in to the Amazon Web Services Management Console using any method except a user name and password. For example, when you access Amazon using your company's single sign-on (SSO) link, that process automatically creates temporary credentials. You also automatically create temporary credentials when you sign in to the console as a user and then switch roles. For more information about switching roles, see Switching to a role (console) in the IAM User Guide.

You can manually create temporary credentials using the Amazon CLI or Amazon API. You can then use those temporary credentials to access Amazon. Amazon recommends that you dynamically generate temporary credentials instead of using long-term access keys. For more information, see Temporary security credentials in IAM.

Service-linked roles for OpenSearch Ingestion

A service-linked role is a type of service role that is linked to an Amazon Web Service. The service can assume the role to perform an action on your behalf. Service-linked roles appear in your Amazon Web Services account and are owned by the service. An IAM administrator can view, but not edit the permissions for service-linked roles.

OpenSearch Ingestion uses a service-linked role called AWSServiceRoleForAmazonOpenSearchIngestionService. The service-linked role named AWSServiceRoleForOpensearchIngestionSelfManagedVpce is also available for pipelines with self-managed VPC endpoints. For details about creating and managing OpenSearch Ingestion service-linked roles, see Using service-linked roles to create OpenSearch Ingestion pipelines.

Identity-based policy examples for OpenSearch Ingestion

By default, users and roles don't have permission to create or modify OpenSearch Ingestion resources. They also can't perform tasks by using the Amazon Web Services Management Console, Amazon Command Line Interface (Amazon CLI), or Amazon API. To grant users permission to perform actions on the resources that they need, an IAM administrator can create IAM policies. The administrator can then add the IAM policies to roles, and users can assume the roles.

To learn how to create an IAM identity-based policy by using these example JSON policy documents, see Creating IAM policies in the IAM User Guide.

For details about actions and resource types defined by Amazon OpenSearch Ingestion, including the format of the ARNs for each of the resource types, see Actions, resources, and condition keys for Amazon OpenSearch Ingestion in the Service Authorization Reference.

Policy best practices

Identity-based policies are very powerful. They determine whether someone can create, access, or delete OpenSearch Ingestion resources in your account. These actions can incur costs for your Amazon Web Services account. When you create or edit identity-based policies, follow these guidelines and recommendations:

Using OpenSearch Ingestion in the console

To access OpenSearch Ingestion within the OpenSearch Service console, you must have a minimum set of permissions. These permissions must allow you to list and view details about the OpenSearch Ingestion resources in your Amazon 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 (such as IAM roles) with that policy.

You don't need to allow minimum console permissions for users that are making calls only to the Amazon CLI or the Amazon API. Instead, allow access to only the actions that match the API operation that you're trying to perform.

The following policy allows a user to access OpenSearch Ingestion within the OpenSearch Service console:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Resource": "*",
            "Effect": "Allow",
            "Action": [
                "osis:ListPipelines",
                "osis:GetPipeline",
                "osis:ListPipelineBlueprints",
                "osis:GetPipelineBlueprint",
                "osis:GetPipelineChangeProgress"
            ]
        }
    ]
}

Alternately, you can use the AmazonOpenSearchIngestionReadOnlyAccess Amazon Web Services managed policy, which grants read-only access to all OpenSearch Ingestion resources for an Amazon Web Services account.

Administering OpenSearch Ingestion pipelines

This policy is an example of a "pipeline admin" policy that allows a user to manage and administer Amazon OpenSearch Ingestion pipelines. The user can create, view, and delete pipelines.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Resource": "arn:aws:osis:region:123456789012:pipeline/*",
            "Action": [
                "osis:CreatePipeline",
                "osis:DeletePipeline",
                "osis:UpdatePipeline",
                "osis:ValidatePipeline",
                "osis:StartPipeline",
                "osis:StopPipeline"
            ],
            "Effect": "Allow"
        },
        {
            "Resource": "*",
            "Action": [
                "osis:ListPipelines",
                "osis:GetPipeline",
                "osis:ListPipelineBlueprints",
                "osis:GetPipelineBlueprint",
                "osis:GetPipelineChangeProgress"
            ],
            "Effect": "Allow"
        }
    ]
}

Ingesting data into an OpenSearch Ingestion pipeline

This example policy allows a user or other entity to ingest data into an Amazon OpenSearch Ingestion pipeline in their account. The user can't modify the pipelines.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Resource": "arn:aws:osis:region:123456789012:pipeline/*",
            "Action": [
                "osis:Ingest"
            ],
            "Effect": "Allow"
        }
    ]
}
