Permissions

If you need to assign different permissions to employees in your enterprise, Identity and Access Management (IAM) is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you flexibly manage resource access.

You can create users using IAM and grant users permissions to implement access control. For example, if you want some of your employees to have the permissions for configuring the resource recorder, you can create IAM users for them and grant them with the required permissions.

If your Huawei Cloudaccount does not need individual IAM users for permissions management, skip this chapter.

IAM can be used free of charge. You pay only for the resources in your account. For more details, see What is IAM?.

Config Permissions

By default, new IAM users do not have permissions. You need to add a user to one or more groups and attach policies or roles to the user groups. Users in a group inherit permissions from the group, so that they can perform operations on cloud services based on the permissions.

Config is a global service. You do not need to repeat Config authorization for different regions or switch regions for accessing Config.

A user with Config read-only permissions can view all resources on the Resource List page.

You can grant permissions by using roles or policies.

Roles: A coarse-grained authorization strategy that defines permissions by job responsibility. Only a limited number of service-level roles are available for authorization. When using roles to grant permissions, you must also assign other roles which the permissions depend on to take effect. However, roles are not an ideal choice for fine-grained authorization and secure access control.
Policy: A type of fine-grained authorization method that defines permissions required to perform operations on specific cloud resources under certain conditions. Authorization using policies is more flexible and help you implement least privilege. Most policies define permissions based on APIs. API actions are the minimum granularity of permissions. For API actions supported by Config, see the Permissions Policies and Supported Actions section in Config API Reference.

Table 1 Config system-defined permissions lists all the system-defined permissions supported by Config.

**Table 1** Config system-defined permissions
Policy	Description	Dependencies
RMS ConsoleFullAccess	Grants full access to Config console. This policy grants you the permissions to perform all actions on the resource list, resource recorder, resource compliance, advanced queries, aggregators, and conformance packages.	RF FullAccess
RMS FullAccess	Grants full access to Config. This policy grants you the permissions to perform all actions on the resource list, resource recorder, resource compliance, advanced queries, aggregators, and conformance packages.	RF FullAccess
RMS ReadOnlyAccess	Grants read-only access to Config. This policy grants you read access to the resource list, resource recorder, resource compliance, advanced queries, aggregators, and conformance packages.	None

An IAM user or IAM Identity Center user may still be denied specific operations on resource recorders, rules, or conformance packages even if they have been granted the RMS ConsoleFullAccess permission. This is because specific operations require IAM agencies. To perform these operations, you need related IAM agencies. The following lists the details.

To create IAM agencies, you need the iam:agencies:createAgency and iam:permissions:grantRoleToAgency permissions. To grant the permission iam:permissions:grantRoleToAgency, specific actions need to be specified.

Table 2 lists the common operations and the system-defined permissions of Config. √ indicates that an operation is supported, and × indicates not supported.
