Permissions

If you need to assign different permissions to employees in your enterprise to access your Cloud Eye resources, you can use IAM to manage fine-grained permissions. IAM provides identity authentication, permissions management, and access control, helping you secure access to your Huawei CloudHuawei Cloud resources.

With IAM, you can use your Huawei Cloud account to create IAM users, and assign permissions to the users to control their access to specific resources. For example, some software developers in your enterprise need to use Cloud Eye resources but should not be allowed to delete the resources of other cloud services or perform any other high-risk operations. In this scenario, you can create IAM users for the software developers and grant them only the permissions required for using Cloud Eye resources.

If your Huawei Cloud account does not require individual IAM users for permissions management, skip this section.

IAM can be used free of charge. You pay only for the resources in your account. For more information about IAM, see What Is IAM.

Cloud Eye Permissions

By default, IAM users do not have permissions. To assign permissions to IAM users, add them to one or more groups, and attach policies or roles to these groups. The users then inherit permissions from the groups to which the users belong, and can perform specific operations on cloud services.

Cloud Eye is a project-level service deployed and accessed in specific physical regions. Cloud Eye permissions are assigned to users in specific regions (such as CN-Hong Kong) and only take effect in these regions. To make the permissions take effect in all regions, assign the permissions to users in each region. When users access Cloud Eye, they need to switch to a region where they have been authorized to use this service.

You can grant users permissions by using roles and policies.

Roles: A type of coarse-grained authorization mechanism that defines permissions related to user responsibilities. This mechanism provides only a limited number of service-level roles for authorization. When using roles to grant permissions, you also need to assign other roles on which the permissions depend to take effect. However, roles are not an ideal choice for fine-grained authorization and secure access control.
Policies: A type of fine-grained authorization mechanism that defines permissions required to perform operations on specific cloud resources under certain conditions. This mechanism allows for more flexible policy-based authorization, meeting requirements for secure access control. For example, you can grant Cloud Eye users only the permissions for managing a certain type of Cloud Eye resources.
A majority of fine-grained policies contain permissions for specific APIs, and permissions are defined using API actions. For the API actions supported by Cloud Eye, see Permissions Policies and Supported Actions.

Table 1 lists the system-defined permissions supported by Cloud Eye.

**Table 1** System-defined permissions
System-Defined Role/Policy Name	Description	Type	Dependency
CES FullAccess	All permissions for Cloud Eye. Users granted these permissions can perform all operations on Cloud Eye.	System-defined policies	Cloud Eye monitoring involves querying resources of other cloud services. This policy contains the resource query permissions of some cloud services. If you encounter permission problems, configure required fine-grained permissions of the involved services. For details, see Supported Cloud Services.
CES ReadOnlyAccess	Read-only permissions for Cloud Eye. Users granted these permissions can only view Cloud Eye data.	System-defined policies	Cloud Eye monitoring involves querying resources of other cloud services. This policy contains the resource query permissions of some cloud services. If you encounter permission problems, configure required fine-grained permissions of the involved services. For details, see Supported Cloud Services.
CES AgentAccess	Permissions required for the Cloud Eye Agent to run NOTE: To ensure that the Cloud Eye Agent can provide services, you need to configure an agency. For details, see How Do I Configure an Agency?	System-defined policies	None
CES Administrator	Administrator permissions for Cloud Eye	System-defined roles	Depends on the Tenant Guest policy. Tenant Guest: a global policy, which must be assigned in the Global project

Table 2 lists common operations supported by the Cloud Eye system-defined permissions.

Roles or Policies Required for Operations on the Cloud Eye Console

To grant an IAM user the permissions to view or use resources of other cloud services on the Cloud Eye console, you must first grant the CES Administrator, CES FullAccess, or CES ReadOnlyAccess policy to the user group to which the user belongs and then grant the dependency roles or policies listed in Table 3 to the user. These dependency policies will allow the IAM user to access resources of other cloud services.

**Table 3** Roles or policies required for operations on the Cloud Eye console
Console Function	Dependent Services	Roles or Policies Required
Cloud service monitoring	Cloud Phone Host (CPH) ROMA Connect: Business Flow Service (BFS) Fast Data Integration (FDI) API Connect (APIC) Cloud Search Service (CSS) Workspace Message & SMS	IAM users with the CES Administrator, CES FullAccess, or CES ReadOnlyAccess permission can view information about cloud service monitoring.
