RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

  • Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.

  • API: The API that you can call to perform the action.

  • Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.

  • Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.

    • For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.

    • For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.

  • Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.

  • Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

The trusted system mode. Set the value to vTPM.

The following instance families support the trusted system mode:

  • Security-enhanced instance families (g7t, c7t, and r7t).

When you create ECS instances of the preceding instance families, you must set this parameter. Take note of the following items:

  • To use the Alibaba Cloud Trusted System, set this parameter to vTPM. The Alibaba Cloud Trusted System performs trusted verification when the instance starts.

  • If you do not use the Alibaba Cloud Trusted System, you do not need to set this parameter. However, if the ECS instance that you create uses the Enclave-based confidential computing mode (SecurityOptions.ConfidentialComputingMode=Enclave), the trusted system is also enabled for the ECS instance.

  • When you use OpenAPI to create a trusted ECS instance, you can call only the RunInstances operation. The CreateInstance operation does not support the SecurityOptions.TrustedSystemMode parameter.

Note

If you specify the instance as a trusted instance when you create it, you can replace the system disk only with an image that supports the trusted system.

For more information about the trusted system, see Overview of trusted features for security-enhanced instances.
