Protection for Mission-Critical Operations

Scenarios

ECS protects against mission-critical operations. If you want to perform a mission-critical operation on the management console, you must enter a credential for identity verification. You can perform the operation only after your identity is verified. For account security, it is a good practice to enable operation protection. The setting will take effect for both the account and IAM users under the account.

Operation protection applies to the following operations: stop, restart, or delete an ECS, reset the password for logging in to an ECS, detach a disk from an ECS, and unbind an EIP from an ECS.

Enabling Operation Protection

Operation protection is disabled by default. Perform the following operations to enable it:

1. Log in to the management console.
2. Move the cursor to the username in the upper right corner of the page and select Security Settings from the drop-down list.
   Figure 1 Security Settings
   
3. On the Security Settings page, choose Critical Operations > Operation Protection > Enable.
   Figure 2 Critical Operations
   
4. On the Operation Protection page, select Enable to enable operation protection.
   When you or the IAM users under your account perform critical operations, for example, deleting ECS resources, you are required to enter a verification code based on the selected verification method.

   

   • When performing a critical operation, you need to choose a verification method from email, SMS, and virtual MFA device.
     • If you have bound only a mobile number, only SMS verification is available.
     • If you have bound only an email address, only email verification is available.
     • If you have not bound an email address, mobile number, or virtual MFA device, you are required to bind one to continue with the critical operation.
   • If you want to change the mobile number, email address, or virtual MFA device, see Basic Information.

Verifying an Identity

After operation protection is enabled, when you perform a mission-critical operation, the system will verify your identity.

• If you have bound an email address, enter the email verification code.
• If you have bound a mobile number, enter the SMS verification code.
• If you have bound a virtual MFA device, enter a 6-digit dynamic verification code of the MFA device.

When you attempt to stop an ECS, select a verification method.
