You can upgrade or downgrade current configurations of your Security Center edition in the Security Center console.
When you purchase Security Center, you must specify the value of the Protected Servers parameter that represents the number of servers to be protected by Security Center. Security Center protects Alibaba Cloud Elastic Compute Service (ECS) instances and third-party servers that have the Security Center agent installed. The default value of the Protected Servers parameter is the total number of your Alibaba Cloud ECS instances and third-party servers that have the Security Center agent installed. The value of the Protected Servers parameter must be no less than the total number of servers within your Alibaba Cloud account. If you want Security Center to protect more servers during the subscription period, we recommend that you estimate the total number of servers within your account and set the Protected Servers parameter to the estimated value.
You can purchase the Security Center Anti-virus, Advanced, Enterprise,or Ultimate edition. If the number of servers or the vCPUs of the servers that require protection exceeds the value of the Protected Servers or the Server vCPUs parameter that you specify, the system prompts you to upgrade Security Center. To continue using Security Center, set the Protected Servers or Server vCPUs parameter to a greater value and pay for the additional quotas. Assume that you have purchased the Security Center Anti-virus, Advanced, or Enterprise edition and set the value of the Protected Servers parameter to 10. To enable Security Center for 13 servers, you must change the value of the Protected Servers parameter to 13 and pay for the three additional servers.
Fees for an upgrade = (Fees of the additional servers + Fees of value-added features) × Number of remaining days within the subscription period
- You must downgrade Security Center before the expiration date. If your subscription expires, you must renew Security Center before you downgrade the service. You can also purchase Security Center of the required configurations after the subscription expires. Security Center retains your statistics and configurations for seven days after the subscription expires. If you do not renew the service within the data retention period, Security Center clears the current statistics and configurations.
- Downgrade refunds are unavailable. A downgrade operation is irreversible. Proceed
with caution when you downgrade Security Center.
Assume that you have reduced the number of servers that can be protected by the web tamper proofing feature of Security Center. If you want to enable this feature for more servers, you must upgrade Security Center.
- Third-party servers that have the Security Center agent installed consume the resource quotas allowed by Security Center. You can perform the following steps to disable protection for a third-party server: Log on to the Security Center console. In the left-side navigation pane, click Assets. On the Assets page, unbind the server that you do not want to protect. After you unbind the server, Security Center releases the resource quota consumed by the server. For more information, see Disassociate an external server.
