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 Manage button is displayed next to Remaining Quota in the Subscription section on the Overview page, your Alibaba Cloud account is in partial protection mode, and you can manage quotas.

  • If no Manage button is displayed, your Alibaba Cloud account is in full protection mode. In full protection mode, quotas are automatically bound to all servers that are added to Security Center. If you want to provide security capabilities only for specific servers, you can upgrade Security Center to switch to the partial protection mode.

    

• If you do not bind quotas to servers when you purchase Security Center that uses the subscription billing method, Security Center automatically binds the purchased quotas to random servers after the purchase is complete. You can manually unbind quotas from servers. Batch unbinding is supported.

• 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 a quota to a server and unbind a quota from a server

If the information about a server is displayed on the Host page in the Security Center console, the server is added to Security Center. You can bind a quota to the server. If the remaining quota is greater than 0, you can bind a quota to the server. You can unbind the quota from the server 30 days after the binding. To bind a quota to a server or unbind a quota from a server, perform the following operations:

1. Log on to the Security Center console. In the top navigation bar, select the region of the asset that you want to manage. You can select China or Outside China.

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

3. Click Manage next to Remaining Quota in the Subscription section.

   You can also go to the Assets > Host page and click Manage in the Remaining Quota section. The Quota Management dialog box appears.

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

   If you want the system to automatically bind quotas to all servers that are added to Security Center, 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 top navigation bar, select the region of the asset that you want to manage. You can select China or Outside China.

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

3. On the Server tab of the Host page, find 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 displayed in the Binding Status column, the quota is not bound to the server, and the server is protected by Security Center Basic. 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.
