Security Center：Manage quotas

Prerequisites

• The Anti-virus, Advanced, Enterprise, or Ultimate edition of Security Center that uses the subscription billing method is purchased. For more information, see Purchase Security Center.

• A server is added to Security Center. For more information, see Install the Security Center agent.

Usage notes

• Starting May 30, 2024 (UTC+8), if you purchase Security Center by using the subscription billing method, you can purchase quotas for protected servers and server cores based on your business requirements. After or during the purchase, you must bind the purchased quotas to servers to use the security capabilities of the Security Center edition that you purchased.

• If you purchase Security Center by using the subscription billing method before May 30, 2024 (UTC+8), take note of the following items:

  • If the Remaining Quota section of the Overview page in the Security Center console shows the Manage option, your Alibaba Cloud account has transitioned to partial protection mode, and you can manage quotas.

  • If the Manage option is absent in the Security Center console, your account is in full protection mode. In this mode, all servers added to Security Center are automatically bound to quotas. As full protection mode will be discontinued, we recommend switching to partial protection mode manually. For more information, see How do I manually upgrade full protection to partial protection mode?

    

• If you purchase Security Center with the subscription billing method and do not immediately bind quotas to servers, Security Center will automatically allocate quotas to active servers in your account to prevent them from going unused. You can unbind these automatically bound quotas at any time, and you can also unbind quotas in batches for efficiency.

  Note

  For automatically bound quotas, there is no time restriction for the initial unbinding. However, if you manually bind these quotas to new servers, you must wait at least 30 days before you can unbind them again.

• You cannot unbind a quota from a server within 30 days after you bind the quota to the server.

• If an Elastic Compute Service (ECS) instance is released or the Security Center agent is uninstalled from a third-party server in the Security Center console, Security Center automatically releases the quota that was bound to the server.

• Note

  If you uninstall the Security Center agent from a server without using the Security Center console, the status of the server on the Host page in the Security Center console changes to Agent Offline. In this case, Security Center does not automatically release the quota that is bound to the server.

Bind or unbind quotas

You can bind quotas to servers listed on the Host page in Security Center, provided there are remaining quotas. Once you manually bind a quota to a server, you cannot unbind it for 30 days.

1. Log on to the Security Center console. In the upper-left corner of the console, select the region where your assets are located: China or Outside China.

2. In the left-side navigation pane, click Overview.

3. Click Remaining Quota on the right side of the page and click Manage.

   Alternatively, navigate to the Assets > Host page. In the Remaining Quota section, click Manage to open the Quota Management dialog box.

4. In the Quota Management dialog box, select Add or Remove operation type and the server that you want to manage, and click OK.

   To automatically bind quotas to newly added servers, select Automatically Add New Servers to Security Center.

   

Check whether the quota is bound to or unbound from the server

1. Log on to the Security Center console. In the upper-left corner of the console, select the region where your assets are located: China or Outside China.

2. In the left-side navigation pane, select Assets > Host.

3. On the Host page, click the Server tab to check the required servers and view the edition of Security Center in the Binding Status column.

   • If Anti-virus, Advanced, Enterprise, or Ultimate is displayed in the Binding Status column, the quota is bound to the server, and the server is protected by the corresponding Security Center edition.

   • If Basic is shown in the Binding Status column, the quota is not bound to the server, and it relies on the detection capabilities of the Basic edition. The server remains unprotected. For more information, see Introduction to Security Center Basic.

   

What to do next

After you bind the quota to the server, you can configure security features for the server. For more information, see Enable features on the Host Protection Settings tab.
