Actions Supported by Role/Policy-based Authorization (Old IAM Version)

This section describes the actions supported by UCS in role/policy-based authorization.

Supported Actions

UCS 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:

Permissions: statements in a policy that allow or deny certain operations
APIs: REST APIs that can be called by a user who has been granted specific permissions.
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 for both IAM and enterprise projects can be used and applied for both IAM and Enterprise Management. Policies that contain actions only for IAM projects can be used and applied to IAM only. For details about the differences between IAM and enterprise management, see What Are the Differences Between IAM and Enterprise Management?
