Basic CAM Concepts

A root account authorizes sub-accounts by binding policies. The policy settings can be specific to the level of API, Resource, User/User Group, Allow/Deny, and Condition.

Account

• Root account: it owns all Tencent Cloud resources and can access any of its resources.
• Sub-account: it includes sub-users and collaborators.
• Sub-user: it is created and fully owned by a root account.
• Collaborator: it has the identity of a root account. After it is added as a collaborator of the current root account, it becomes one of the sub-accounts of the current root account and can switch back to its root account identity.
• Identity credential: it includes login credentials and access certificates. Login credential refers to a user's login name and password. Access certificate refers to Tencent Cloud API keys (SecretId and SecretKey).

Resource and permission

• Resource: it is an object manipulated in Tencent Cloud services. TDMQ resources include clusters, namespaces, topics, and groups.
• Permission: it is an authorization that allows or forbids users to perform certain operations. By default, a root account has full access to all resources under it, while a sub-account does not have access to any resources under its root account.
• Policy: it is a syntax rule that defines and describes one or more permissions. The root account performs authorization by associating policies with users/user groups.
