<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 Verified Permissions 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 Verified Permissions identity and access](security_iam_troubleshoot.md))
+ **Service administrator** - determine user access and submit permission requests (see [How Amazon Verified Permissions works with IAM](security_iam_service-with-iam.md))
+ **IAM administrator** - write policies to manage access (see [Identity-based policy examples for Amazon Verified Permissions](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 within your AWS account that has specific permissions. It is similar to an IAM user, but is not associated with a specific person. You can temporarily assume an IAM role in the AWS Management Console by [switching roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-console.html). You can assume a role by calling an AWS CLI or AWS API operation or by using a custom URL. For more information about methods for using roles, see [Using IAM roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html) in the *IAM User Guide*.

IAM roles with temporary credentials are useful in the following situations:
+ **Federated user access** – To assign permissions to a federated identity, you create a role and define permissions for the role. When a federated identity authenticates, the identity is associated with the role and is granted the permissions that are defined by the role. For information about roles for federation, see [ Create a role for a third-party identity provider (federation)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create_for-idp.html) in the *IAM User Guide*. If you use IAM Identity Center, you configure a permission set. To control what your identities can access after they authenticate, IAM Identity Center correlates the permission set to a role in IAM. For information about permissions sets, see [ Permission sets](https://docs.aws.amazon.com/singlesignon/latest/userguide/permissionsetsconcept.html) in the *AWS IAM Identity Center User Guide*. 
+ **Temporary IAM user permissions** – An IAM user or role can assume an IAM role to temporarily take on different permissions for a specific task.
+ **Cross-account access** – You can use an IAM role to allow someone (a trusted principal) in a different account to access resources in your account. Roles are the primary way to grant cross-account access. However, with some AWS services, you can attach a policy directly to a resource (instead of using a role as a proxy). To learn the difference between roles and resource-based policies for cross-account access, see [How IAM roles differ from resource-based policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_compare-resource-policies.html) in the *IAM User Guide*.
+ **Applications running on Amazon EC2** – You can use an IAM role to manage temporary credentials for applications that are running on an EC2 instance and making AWS CLI or AWS API requests. This is preferable to storing access keys within the EC2 instance. To assign an AWS role to an EC2 instance and make it available to all of its applications, you create an instance profile that is attached to the instance. An instance profile contains the role and enables programs that are running on the EC2 instance to get temporary credentials. For more information, see [Use an IAM role to grant permissions to applications running on Amazon EC2 instances](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2.html) in the *IAM User Guide*. 

To learn whether to use IAM roles or IAM users, see [When to create an IAM role (instead of a user)](https://docs.aws.amazon.com/IAM/latest/UserGuide/id.html#id_which-to-choose_role) 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*.

## Identity-based policies for Verified Permissions
<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 Verified Permissions
<a name="security-iam-service-with-iam-id-based-policies-examples"></a>



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

## Resource-based policies within Verified Permissions
<a name="security-iam-service-with-iam-resource-based-policies"></a>


|  |  | 
| --- |--- |
|  Supports resource-based policies  |  No  | 

Resource-based policies are JSON policy documents that you attach to a resource. Examples of resource-based policies are IAM *role trust policies* and Amazon S3 *bucket policies*. In services that support resource-based policies, service administrators can use them to control access to a specific resource. For the resource where the policy is attached, the policy defines what actions a specified principal can perform on that resource and under what conditions. You must [specify a principal](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html) in a resource-based policy. Principals can include accounts, users, roles, federated users, or AWS services.

To enable cross-account access, you can specify an entire account or IAM entities in another account as the principal in a resource-based policy. For more information, see [Cross account resource access in IAM](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies-cross-account-resource-access.html) in the *IAM User Guide*.

## Policy actions for Verified Permissions
<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 Verified Permissions actions, see [Actions defined by Amazon Verified Permissions](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonverifiedpermissions.html#amazonverifiedpermissions-actions-as-permissions) in the *Service Authorization Reference*.

Policy actions in Verified Permissions use the following prefix before the action:

```
verifiedpermissions
```

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

```
"Action": [
      "verifiedpermissions:action1",
      "verifiedpermissions:action2"
         ]
```

You can specify multiple actions using wildcards (\$1). For example, to specify all actions that begin with the word `Get`, include the following action:

```
"Action": "verifiedpermissions:Get*"
```

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

## Policy resources for Verified Permissions
<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": "*"
```

To see a list of Verified Permissions resource types and their ARNs, see [Resource types defined by Amazon Verified Permissions](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonverifiedpermissions.html#amazonverifiedpermissions-resources-for-iam-policies) in the *Service Authorization Reference*. To learn with which actions you can specify the ARN of each resource, see [Actions defined by Amazon Verified Permissions](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonverifiedpermissions.html#amazonverifiedpermissions-actions-as-permissions).

## Policy condition keys for Verified Permissions
<a name="security-iam-service-with-iam-id-based-policies-conditionkeys"></a>


|  |  | 
| --- |--- |
|  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](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*.

## ACLs in Verified Permissions
<a name="security-iam-service-with-iam-acls"></a>


|  |  | 
| --- |--- |
|  Supports ACLs  |  No  | 

Access control lists (ACLs) control which principals (account members, users, or roles) have permissions to access a resource. ACLs are similar to resource-based policies, although they do not use the JSON policy document format.

## ABAC with Verified Permissions
<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*.

## Using temporary credentials with Verified Permissions
<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*.

## Cross-service principal permissions for Verified Permissions
<a name="security-iam-service-with-iam-principal-permissions"></a>


|  |  | 
| --- |--- |
|  Supports principal permissions  |  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 Verified Permissions
<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*. 

## Service-linked roles for Verified Permissions
<a name="security-iam-service-with-iam-roles-service-linked"></a>


|  |  | 
| --- |--- |
|  Supports service-linked roles  |  No  | 

 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](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html). 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.

# IAM policies for Verified Permissions
<a name="security-iam-getting-started-policies"></a>

Verified Permissions manages the permissions of users within your application. In order for your application to call the Verified Permissions APIs or for AWS Management Console users to be allowed to manage Cedar policies in a Verified Permissions policy store, you must add the necessary IAM permissions.

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](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 (listed below). 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](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html) in the IAM User Guide.

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

By default, users and roles don't have permission to create or modify Verified Permissions resources. They also can't perform tasks by using the AWS Management Console, AWS Command Line Interface (AWS CLI), or AWS API. An IAM administrator must create IAM policies that grant users and roles permission to perform actions on the resources that they need. The administrator must then attach those policies for users that require them.

To learn how to create an IAM identity-based policy by using these example JSON policy documents, see [Creating IAM policies](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 Verified Permissions, including the format of the ARNs for each of the resource types, see see [Actions, resources, and condition keys for Amazon Verified Permissions](https://docs.aws.amazon.com/service-authorization/latest/reference/list_amazonverifiedpermissions.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 Verified Permissions 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 Verified Permissions console
<a name="security-iam-id-based-policy-examples-console"></a>

To access the Amazon Verified Permissions console, you must have a minimum set of permissions. These permissions must allow you to list and view details about the Verified Permissions 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 Verified Permissions console, also attach the Verified Permissions `ConsoleAccess` or `ReadOnly` AWS managed policy to the entities. For more information, see [Adding permissions to a user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_change-permissions.html#users_change_permissions-add-console) in the *IAM User Guide*.

## Allow users to view their own permissions
<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 Verified Permissions
<a name="security-iam-awsmanpol"></a>







To add permissions to users, groups, and roles, it is easier to use AWS managed policies than to write policies yourself. It takes time and expertise to [create IAM customer managed policies](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_create-console.html) that provide your team with only the permissions they need. To get started quickly, you can use our AWS managed policies. These policies cover common use cases and are available in your AWS account. For more information about AWS managed policies, 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*.

AWS services maintain and update AWS managed policies. You can't change the permissions in AWS managed policies. Services occasionally add additional permissions to an AWS managed policy to support new features. This type of update affects all identities (users, groups, and roles) where the policy is attached. Services are most likely to update an AWS managed policy when a new feature is launched or when new operations become available. Services do not remove permissions from an AWS managed policy, so policy updates won't break your existing permissions.

Additionally, AWS supports managed policies for job functions that span multiple services. For example, the **ReadOnlyAccess** AWS managed policy provides read-only access to all AWS services and resources. When a service launches a new feature, AWS adds read-only permissions for new operations and resources. For a list and descriptions of job function policies, see [AWS managed policies for job functions](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies_job-functions.html) in the *IAM User Guide*.









## AWS managed policy: AmazonVerifiedPermissionsFullAccess
<a name="security-iam-awsmanpol-AmazonVerifiedPermissionsFullAccess"></a>

The `AmazonVerifiedPermissionsFullAccess` managed policy grants full access to Verified Permissions. To work with Amazon Cognito-based identity sources, you'll need to attach a separate policy, such as the [AmazonCognitoReadOnly](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AmazonCognitoReadOnly.html) policy.

## AWS managed policy: AmazonVerifiedPermissionsReadOnlyAccess
<a name="security-iam-awsmanpol-AmazonVerifiedPermissionsReadOnlyAccess"></a>

The `AmazonVerifiedPermissionsReadOnlyAccess` managed policy grants read-only access to Verified Permissions.

This policy grants access to all read operations of Amazon Verified Permissions, including the authorization query APIs `IsAuthorized` and `IsAuthorizedWithToken`.

**Note**  
Access to `BatchIsAuthorized` and `BatchIsAuthorizedWithToken` are granted automatically when access is granted to `IsAuthorized` and `IsAuthorizedWithToken`, respectively.

# Troubleshooting Amazon Verified Permissions 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 Verified Permissions and IAM.

**Topics**
+ [I am not authorized to perform an action in Verified Permissions](#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 Verified Permissions resources](#security-iam-troubleshoot-cross-account-access)

## I am not authorized to perform an action in Verified Permissions
<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 `verifiedpermissions:GetWidget` permissions.

```
User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: verifiedpermissions: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 `verifiedpermissions: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 Verified Permissions.

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 Verified Permissions. 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 Verified Permissions 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.
