Security Center protects servers that are not deployed on Alibaba Cloud and have the Securty Center agent installed. If you do not require protection for these servers, you can unbind the servers from Security Center. This topic describes how to unbind a server that is not deployed on Alibaba Cloud from Security Center.

Prerequisites

Background information

If the server that is not deployed on Alibaba Cloud shuts down but still has unhandled vulnerabilities or alerts, you can unbind the server from Security Center on the Assets page. This prevents the unhandled vulnerabilities and alerts from affecting the security score of your assets. If you no longer want Security Center to protect the server, you can directly uninstall the Security Center agent. For more information about how to uninstall the Security Center agent, see Uninstall the Security Center agent.

After you unbind a server from Security Center, the server is no longer displayed in the server list on the Assets page. Security Center no longer protects the server. However, all processes and files in the directory of the Security Center agent are retained on the server. If you want Security Center to protect the server again, start up the server. After the server connects to the Internet, the Security Center agent automatically runs on the server, and Security Center starts to protect the server.

If you uninstall the Security Center agent, all processes and files in the directory of the Security Center agent are deleted from the server.

Note
  • You can unbind only the servers that are not deployed on Alibaba Cloud from Security Center. If you use an Alibaba Cloud Elastic Compute Service (ECS) instance, you do not need to perform the unbinding operation. If you uninstall the Security Center agent from an ECS instance, the ECS instance is still displayed in the server list on the Assets page.
  • After you unbind a server that is not deployed on Alibaba Cloud from Security Center, the server no longer consumes the quota of protected servers or protected server vCPUs. This way, you can install the Security Center agent on other servers based on your business requirements.

Procedure

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, click Assets.
  3. On the Assets page, click the Server(s) tab.

    In the server list, select the server that you want to unbind from Security Center and choose More Operations > Unbind below the server list. Unbind
  5. Click OK.
    After you unbind the server from Security Center, the server is no longer displayed in the server list.
