Permissions and Supported Actions

This chapter describes fine-grained permissions management for your RFS resources. If your account does not need individual IAM users, you can skip the operations in this chapter.

By default, new IAM users do not have permissions assigned. You need to add a user to one or more groups, and attach permissions policies or roles to these groups. Users inherit permissions from the groups to which they are added and can perform specified operations on cloud services based on the permissions.

You can grant users permissions by using roles and policies. Roles are a type of service-based, coarse-grained authorization mechanism provided by IAM to define permissions that match user responsibilities. Policies define API-based permissions for operations on specific resources under certain conditions, allowing for more fine-grained, secure access control of cloud resources.

Policy-based authorization is useful if you want to allow or deny the access to an API.

An account has all the permissions required to call all APIs, but IAM users must be assigned the permissions to call the required APIs. The permissions required for calling an API are determined by the actions supported by the API. Only users who have been granted permissions can call the API successfully. For example, if an IAM user wants to query ECSs using an API, the user must have been granted permissions that allow the ecs:servers:list action.

Supported Actions in IAM

RFS provides system-defined policies that can be directly used in IAM. You can also create custom policies to supplement system-defined policies for more refined access control. Operations supported by policies are specific to APIs. The following are common concepts related to policies:

Permission: a statement in a policy that allows or denies certain operations.
APIs: APIs that can be called in a custom policy.
Actions: specific operations that are allowed or denied in a custom policy.
Dependencies: actions which a specific action depends on. When allowing an action for a user, you also need to allow any existing action dependencies for that user.
IAM projects/Enterprise projects: the authorization scope of a custom policy. A custom policy can be applied to IAM projects or enterprise projects or both. Policies that contain actions supporting both IAM and enterprise projects can be assigned to user groups and take effect in both IAM and Enterprise Management. Policies that only contain actions supporting IAM projects can be assigned to user groups and only take effect for IAM. Such policies will not take effect if they are assigned to user groups in enterprise management. For details about the differences between IAM and enterprise projects, see What Are the Differences Between IAM and Enterprise Management?

The check mark (√) and cross symbol (x) respectively indicate that an action takes effect or does not take effect for the corresponding type of projects.

RFS supports the following actions in custom policies.
