# Identity and access management for AWS Billing Conductor 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 Billing Conductor 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 AWS Billing Conductor works with IAM ](security_iam_service-with-iam.md) + [ # AWS Billing Conductor identity-based policy examples ](security_iam_id-based-policy-examples.md) ## Audience 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 AWS Billing Conductor identity and access](security_iam_troubleshoot.md)) + **Service administrator** - determine user access and submit permission requests (see [How AWS Billing Conductor works with IAM](security_iam_service-with-iam.md)) + **IAM administrator** - write policies to manage access (see [AWS Billing Conductor identity-based policy examples](security_iam_id-based-policy-examples.md)) ## Authenticating with identities 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 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*. ### IAM users and groups 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 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 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 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 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) 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 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 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 AWS Billing Conductor works with IAM Before you use IAM to manage access to Billing Conductor, you should understand what IAM features are available to use with Billing Conductor. To get a high-level view of how Billing Conductor 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*. **Topics** + [ ## Billing Conductor identity-based policies ](#security_iam_service-with-iam-id-based-policies) + [ ## Billing Conductor resource-based policies ](#security_iam_service-with-iam-resource-based-policies) + [ ## Access control lists (ACLs) ](#security_iam_service-with-iam-acls) + [ ## Authorization based on Billing Conductor tags ](#security_iam_service-with-iam-tags) + [ ## Billing Conductor IAM roles ](#security_iam_service-with-iam-roles) ## Billing Conductor identity-based policies 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. Billing Conductor supports specific actions, 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 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. Policy actions in Billing Conductor use the following prefix before the action: `Billing Conductor:`. For example, to grant someone permission to run an Amazon EC2 instance with the Amazon EC2 `RunInstances` API operation, you include the `ec2:RunInstances` action in their policy. Policy statements must include either an `Action` or `NotAction` element. Billing Conductor defines its own set of actions that describe tasks that you can perform with this service. To specify multiple actions in a single statement, separate them with commas as follows: ``` "Action": [ "ec2:action1", "ec2:action2" ``` You can specify multiple actions using wildcards (\$1). For example, to specify all actions that begin with the word `Describe`, include the following action: ``` "Action": "ec2:Describe*" ``` To see a list of Billing Conductor actions, see [Actions Defined by AWS Billing Conductor](https://docs.aws.amazon.com/IAM/latest/UserGuide/list_awsbillingconductor.html#awsbillingconductor-actions-as-permissions) in the *IAM User Guide*. ### Resources 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": "*" ``` The Amazon EC2 instance resource has the following ARN: ``` arn:${Partition}:ec2:${Region}:${Account}:instance/${InstanceId} ``` 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 `i-1234567890abcdef0` instance in your statement, use the following ARN: ``` "Resource": "arn:aws:ec2:us-east-1:123456789012:instance/i-1234567890abcdef0" ``` To specify all instances that belong to a specific account, use the wildcard (\$1): ``` "Resource": "arn:aws:ec2:us-east-1:123456789012:instance/*" ``` Some Billing Conductor actions, such as those for creating resources, cannot be performed on a specific resource. In those cases, you must use the wildcard (\$1). ``` "Resource": "*" ``` Many Amazon EC2 API actions involve multiple resources. For example, `AttachVolume` attaches an Amazon EBS volume to an instance, so an IAM user must have permissions to use the volume and the instance. To specify multiple resources in a single statement, separate the ARNs with commas. ``` "Resource": [ "resource1", "resource2" ``` To see a list of Billing Conductor resource types and their ARNs, see [Resources Defined by AWS Billing Conductor](https://docs.aws.amazon.com/IAM/latest/UserGuide/list_awsbillingconductor.html#awsbillingconductor-resources-for-iam-policies) in the *IAM User Guide*. To learn with which actions you can specify the ARN of each resource, see [Actions Defined by AWS Billing Conductor](https://docs.aws.amazon.com/IAM/latest/UserGuide/list_awsbillingconductor.html#awsbillingconductor-actions-as-permissions). ### Condition keys 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*. Billing Conductor defines its own set of condition keys and also supports 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*. All Amazon EC2 actions support the `aws:RequestedRegion` and `ec2:Region` condition keys. For more information, see [Example: Restricting Access to a Specific Region](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ExamplePolicies_EC2.html#iam-example-region). To see a list of Billing Conductor condition keys, see [Condition Keys for AWS Billing Conductor](https://docs.aws.amazon.com/IAM/latest/UserGuide/list_awsbillingconductor.html#awsbillingconductor-policy-keys) in the *IAM User Guide*. To learn with which actions and resources you can use a condition key, see [Actions Defined by AWS Billing Conductor](https://docs.aws.amazon.com/IAM/latest/UserGuide/list_awsbillingconductor.html#awsbillingconductor-actions-as-permissions). ### Examples To view examples of Billing Conductor identity-based policies, see [AWS Billing Conductor identity-based policy examples](security_iam_id-based-policy-examples.md). ## Billing Conductor resource-based policies Resource-based policies are JSON policy documents that specify what actions a specified principal can perform on the Billing Conductor resource and under what conditions. Amazon S3 supports resource-based permissions policies for Amazon S3 *buckets*. Resource-based policies let you grant usage permission to other accounts on a per-resource basis. You can also use a resource-based policy to allow an AWS service to access your Amazon S3 *buckets*. 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](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_principal.html). Adding a cross-account principal to a resource-based policy is only half of establishing the trust relationship. When the principal and the resource are in different AWS accounts, you must also grant the principal entity permission to access the resource. Grant permission by attaching an identity-based policy to the entity. However, if a resource-based policy grants access to a principal in the same account, no additional identity-based policy is required. For more information, 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*. The Amazon S3 service supports only one type of resource-based policy called a **bucket* policy*, which is attached to a *bucket*. This policy defines which principal entities (accounts, users, roles, and federated users) can perform actions on the *Billing Conductor*. ### Examples To view examples of Billing Conductor resource-based policies, see [AWS Billing Conductor resource-based policy examples](security_iam_resource-based-policy-examples.md), ## Access control lists (ACLs) Access control lists (ACLs) are lists of grantees that you can attach to resources. They grant accounts permissions to access the resource to which they are attached. You can attach ACLs to an Amazon S3 *bucket* resource. With Amazon S3 access control lists (ACLs), you can manage access to *bucket* resources. Each *bucket* has an ACL attached to it as a subresource. It defines which AWS accounts, IAM users or groups of users, or IAM roles are granted access and the type of access. When a request is received for a resource, AWS checks the corresponding ACL to verify that the requester has the necessary access permissions. When you create a *bucket* resource, Amazon S3 creates a default ACL that grants the resource owner full control over the resource. In the following example *bucket* ACL, John Doe is listed as the owner of the *bucket* and is granted full control over that *bucket*. An ACL can have up to 100 grantees. ``` c1daexampleaaf850ea79cf0430f33d72579fd1611c97f7ded193374c0b163b6 john-doe c1daexampleaaf850ea79cf0430f33d72579fd1611c97f7ded193374c0b163b6 john-doe FULL_CONTROL ``` The ID field in the ACL is the AWS account canonical user ID. To learn how to view this ID in an account that you own, see [Finding an AWS Account Canonical User ID](https://docs.aws.amazon.com/general/latest/gr/acct-identifiers.html#FindingCanonicalId). ## Authorization based on Billing Conductor tags You can attach tags to Billing Conductor resources or pass tags in a request to Billing Conductor. 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 `Billing Conductor:ResourceTag/key-name`, `aws:RequestTag/key-name`, or `aws:TagKeys` condition keys. ## Billing Conductor IAM roles 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 Billing Conductor 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). Billing Conductor supports using temporary credentials. ### Service-linked roles [Service-linked roles](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role) allow AWS services to access resources in other services to complete an action on your behalf. Service-linked roles appear in your IAM account and are owned by the service. An IAM administrator can view but not edit the permissions for service-linked roles. ### Service roles This feature allows a service to assume a [service role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-role) on your behalf. This role allows the service to access resources in other services to complete an action on your behalf. Service roles appear in your IAM account and are owned by the account. This means that an IAM administrator can change the permissions for this role. However, doing so might break the functionality of the service. Billing Conductor supports service roles. ### Choosing an IAM role in Billing Conductor When you create a resource in Billing Conductor, you must choose a role to allow Billing Conductor to access Amazon EC2 on your behalf. If you have previously created a service role or service-linked role, then Billing Conductor provides you with a list of roles to choose from. It's important to choose a role that allows access to start and stop Amazon EC2 instances. # AWS Billing Conductor identity-based policy examples By default, IAM users and roles don't have permission to create or modify Billing Conductor resources. They also can't perform tasks using the AWS Management Console, 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) + [ ## Billing Conductor identity-based policy examples ](#security_policy-examples) + [ # AWS managed policies for AWS Billing Conductor ](security-iam-awsmanpol.md) + [ # AWS Billing Conductor resource-based policy examples ](security_iam_resource-based-policy-examples.md) + [ # Troubleshooting AWS Billing Conductor identity and access ](security_iam_troubleshoot.md) ## Policy best practices Identity-based policies determine whether someone can create, access, or delete Billing Conductor 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*. ## Billing Conductor identity-based policy examples This topic contains example policies that you can attach to your IAM user or group to control access to your account's information and tools. **Topics** + [ ### Granting full access to the Billing Conductor console ](#security_iam_id-based-policy-examples-console) + [ ### Granting full access to the Billing Conductor API ](#security_iam_id-based-policy-examples-fullAPI) + [ ### Granting read-only access to the Billing Conductor console ](#security_iam_id-based-policy-examples-readonly) + [ ### Granting Billing Conductor access through the AWS Billing console ](#security_iam_id-based-policy-examples-ABCthroughbilling) + [ ### Granting Billing Conductor access through AWS Cost and Usage Reports ](#security_iam_id-based-policy-examples-ABCthroughCUR) + [ ### Granting Billing Conductor access to the import organizational unit feature ](#security_iam_id-based-policy-examples-ABCaccessOU) + [ ### Denying AWS Billing and Cost Explorer access to services and features that don't support pro forma costs ](#deny-access-proforma-costs) + [ ### Creating a pro forma CUR by billing group ](#allow-legacy-cur) ### Granting full access to the Billing Conductor console To access the Billing Conductor console, you must have a minimum set of permissions. These permissions must allow you to list and view details about the Billing Conductor 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. To ensure that those entities can still use the Billing Conductor console, also attach the following 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*: In addition to the `billingconductor:*` permissions, `pricing:DescribeServices` is required for pricing rule creation, and `organizations:ListAccounts` is required to list linked accounts that are linked to the payer account. ------ #### [ JSON ] **** ``` { "Version":"2012-10-17", "Statement": [ { "Effect": "Allow", "Action": "billingconductor:*", "Resource": "*" }, { "Effect": "Allow", "Action": [ "organizations:ListAccounts", "organizations:DescribeAccount" ], "Resource": "*" }, { "Effect": "Allow", "Action": "pricing:DescribeServices", "Resource": "*" } ] } ``` ------ You don't need to allow minimum console permissions for users that are making calls only to the AWS CLI or the AWS API.

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: AWSBillingConductorFullAccess The AWSBillingConductorFullAccess managed policy grants complete access to AWS Billing Conductor console and APIs. Users can list, create, and delete AWS Billing Conductor resources. To view the permissions for this policy, see [AWSBillingConductorFullAccess](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSBillingConductorFullAccess.html) in the *AWS Managed Policy Reference*. ## AWS managed policy: AWSBillingConductorReadOnlyAccess The AWSBillingConductorReadOnlyAccess managed policy grants read-only access to AWS Billing Conductor console and APIs. Users can view and list all AWS Billing Conductor resources. Users can't create or delete resources. To view the permissions for this policy, see [AWSBillingConductorReadOnlyAccess](https://docs.aws.amazon.com/aws-managed-policy/latest/reference/AWSBillingConductorReadOnlyAccess.html) in the *AWS Managed Policy Reference*. ## AWS Billing Conductor updates to AWS managed policies View details about updates to AWS managed policies for AWS Billing Conductor since this service began tracking these changes.

However, the request must originate from the range of IP addresses specified in the condition. The condition in this statement identifies the 54.240.143.\$1 range of allowed Internet Protocol version 4 (IPv4) IP addresses, with one exception: 54.240.143.188. The `Condition` block uses the `IpAddress` and `NotIpAddress` conditions and the `aws:SourceIp` condition key, which is an AWS wide condition key. For more information about these condition keys, see [Specifying Conditions in a Policy](https://docs.aws.amazon.com/AmazonS3/latest/userguide/amazon-s3-policy-keys.html). The`aws:sourceIp` IPv4 values use the standard CIDR notation. For more information, see [IP Address Condition Operators](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements_condition_operators.html#Conditions_IPAddress) in the *IAM User Guide*. ------ #### [ JSON ] **** ``` { "Version":"2012-10-17", "Id": "S3PolicyId1", "Statement": [ { "Sid": "IPAllow", "Effect": "Allow", "Principal": "*", "Action": "s3:*", "Resource": "arn:aws:s3:::amzn-s3-demo-bucket1/*", "Condition": { "IpAddress": {"aws:SourceIp": "54.240.143.0/24"}, "NotIpAddress": {"aws:SourceIp": "54.240.143.188/32"} } } ] } ``` ------ # Troubleshooting AWS Billing Conductor identity and access Use the following information to help you diagnose and fix common issues that you might encounter when working with Billing Conductor and IAM. **Topics** + [ ## I am not authorized to perform an action in Billing Conductor ](#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 Billing Conductor resources ](#security_iam_troubleshoot-cross-account-access) ## I am not authorized to perform an action in Billing Conductor 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 user name and password. The following example error occurs when the `mateojackson` IAM user tries to use the console to view details about a *Billing Conductor* but does not have `Billing Conductor:GetWidget` permissions. ``` User: arn:aws:iam::123456789012:user/mateojackson is not authorized to perform: Billing Conductor:GetWidget on resource: my-example-Billing Conductor ``` In this case, Mateo asks his administrator to update his policies to allow him to access the `my-example-Billing Conductor` resource using the `Billing Conductor:GetWidget` action. ## I am not authorized to perform iam:PassRole 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 Billing Conductor. 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 Billing Conductor. 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 Billing Conductor resources 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.
