Permissions Management

If you need to assign different permissions to employees in your enterprise to access your AOM resources, 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 secure access to your AOM resources.

With IAM, you can use your account to create IAM users for your employees, and assign permissions to the users to control their access to specific types of resources. For example, some software developers in your enterprise need to use AOM resources but are not allowed to delete them or perform any high-risk operations such as deleting application discovery rules. To achieve this result, you can create IAM users for the software developers and grant them only the permissions required for using AOM resources.

If your account does not need individual IAM users for permissions management, you may skip over this chapter.

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

AOM Permissions

By default, new IAM users do not have any permissions assigned. You need to add a user to one or more groups, and assign permissions policies or roles to these groups. The user then inherits permissions from the groups it is a member of. This process is called authorization. After authorization, the user can perform specified operations on AOM.

AOM is a project-level service deployed and accessed in specific physical regions. To assign AOM permissions to a user group, specify the scope as region-specific projects and select projects for the permissions to take effect. If All projects is selected, the permissions will take effect for the user group in all region-specific projects. When accessing AOM, the users 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 coarse-grained authorization mechanism provided by IAM to define permissions based on users' job responsibilities. This mechanism provides only a limited number of service-level roles for authorization. Huawei Cloud services depend on each other. When you grant permissions using roles, you may also need to attach dependent roles. 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 Elastic Cloud Server (ECS) users only the permissions for managing a certain type of ECSs. Most policies define permissions based on APIs. For the API actions supported by AOM, see Permissions Policies and Supported Actions.

Roles/Policies Required by AOM Dependent Services

If an IAM user needs to view data or use functions on the AOM console, grant the AOM FullAccess or AOM ReadOnlyAccess policy to the user group to which the user belongs and then add the roles or policies required by AOM dependent services by referring to Table 7.

When a user subscribes to AOM for the first time, AOM will automatically create a service agency. In addition to the AOM FullAccess permission, the user must be granted the Security Administrator permission.

**Table 7** Roles/Policies required by AOM dependent services
Console Function	Dependent Service	Policy/Role Required
Workload monitoring Cluster monitoring	CCE	To use workload and cluster monitoring, you need to set the CCE ReadOnlyAccess permission.
Data subscription	Distributed Message Service (DMS) for Kafka	To use data subscription, you need to set the DMS ReadOnlyAccess permission.
