Identity Authentication and Access Control

IAM Permission Policies

Identity and Access Management (IAM) is a basic service provided by Huawei Cloud for permissions management, access control, and identity authentication. You can use IAM to create and manage users and user groups, grant permissions to allow or deny their access to cloud services and resources, and configure policies to improve account and resource security. IAM also provides you with multiple secure access credentials.

You can use IAM to control access to your SMN resources. IAM permissions define which actions on your cloud resources are allowed or denied. 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.

After creating an IAM user, the administrator needs to add it to a user group and grant the permissions required by SMN to the user group. Then, all users in this group automatically inherit the granted permissions. For details about the system permissions and policies supported by SMN, see Permissions Management.

Topic Policies

The topic creator has the right to configure topic policies. Using topic policies, you can specify which users and cloud services can perform a certain operation on a topic, for example, querying topic details and publishing messages. Topic creators always have permissions over a topic even if they grant topic permissions to other users.

For details, see Configuring Topic Policies.
