Create security-enhanced instances

Create a security-enhanced instance in the ECS console

The procedure for creating a security-enhanced instance in the ECS console is similar to that for creating a non-security-enhanced instance. However, you must pay attention to some specific options when you create a security-enhanced instance. This procedure describes the specific configurations to be made when you create an instance of the c6t instance family. For other general configurations, see Create an instance by using the wizard.

1. Log on to the ECS console.
2. In the left-side navigation pane, choose Instances & Images > Instances.
3. Click Create Instance.
4. Configure the settings in the Basic Configurations step.
   Take note of the following items:

   • Instance Type: You can filter and select a c6t instance type.
   • Image: You can select Alibaba Cloud Linux 2.1903 64-bit (Trusted) or CentOS 7.8 64-bit (Trusted).
     Note When you create a security-enhanced instance, Trusted System is automatically selected. The Alibaba Cloud trusted system verifies the instance when the instance starts. If you want to use a self-managed trusted service system, you can clear Trusted System.
5. Click Next: Networking. If the Enable Key Management Service (KMS) dialog box appears, click Enable.
   KMS must be enabled. Otherwise, the security-enhanced instance cannot be created. If you have enabled KMS, the dialog box does not appear. Proceed with the next step.
6. Configure the settings in the Networking step.
7. In the System Configurations step, specify RAM Role.
   If Trusted System is enabled for your instance, you must specify a RAM role for the instance. The RAM role must be granted permissions to access the trusted services. Alibaba Cloud provides you with the corresponding AliyunECSInstanceForYundunSysTrustRole service role. We recommend that you configure and select this role by performing the following steps.

   Note If you need more precise or customized configurations, create a role and grant it permissions based on your needs. When you create a RAM role, you must take some precautions. For more information, see Precautions on granting permissions to RAM roles.
   1. Click here to authorize.
      
   2. In the Cloud Resource Access Authorization message, click Confirm Authorization.
   3. In the message that appears, click Confirm Authorization.
   4. Click Authorized.
      
   5. Select AliyunECSInstanceForYundunSysTrustRole as the RAM role.
      
   Note You can also skip the authorization step and grant permissions after the instance is created. For more information, see the Bind an instance RAM role section.
8. Follow the wizard to create the instance.
