Fundamental information

Product Abbreviation in CAM Console Authorization by Tag Authorization Granularity IP Restriction
Auto Scaling as Supported Supported Resource level Partially supported

Note：

The authorization granularity of cloud products is divided into three levels: service level, operation level, and resource level, based on the degree of granularity.

  • Service level: It defines whether a user has the permission to access the service as a whole. A user can have either full access or no access to the service. For the authorization granularity of cloud products at service level, the authorization of specific APIs are not supported.
  • Operation level: It defines whether a user has the permission to call a specific API of the service. For example, granting an account read-only access to the CVM service is an authorization at the operation level.
  • Resource level: It is the finest authorization granularity which defines whether a user has the permission to access specific resources. For example, granting an account read/write access to a specific CVM instance is an authorization at the resource level.

API authorization granularity

Two authorization granularity levels of API are supported: resource level, and operation level.

  • Resource level: It supports the authorization of a specific resource.
  • Operation level: It does not support the authorization of a specific resource. If the policy syntax restricts a specific resource during authorization, CAM will determine that this API is not within the scope of authorization, and deem it as unauthorized.
