Actions Supported by Policy-based Authorization

This section describes the actions supported by policy-based authorization in DEW.

Supported Actions

DEW provides system-defined policies that can be directly used in IAM. You can also create custom policies and use them to supplement system-defined policies, implementing 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.
Dependent actions: When assigning an action to users, you also need to assign dependent permissions for that action to take effect.
IAM or enterprise projects: Type of projects for which an action will take effect. For example, if you set the authorization scope of a custom policy to both IAM projects and enterprise projects, the policy takes effect for user groups in either IAM or enterprise projects. If an action supports only IAM projects, the custom policy that contains this action will take effect only for user groups in IAM. Administrators can check whether an action supports IAM projects or enterprise projects in the action list. "√" indicates that the action supports the project and "×" indicates that the action does not support the project. For details about the differences between IAM and enterprise management, see What Are the Differences Between IAM and Enterprise Management?

The following content describes the custom policy authorization supported by DEW.
