A server can be protected by Security Center only after the Security Center agent is installed. This topic describes how the Security Center agent works, information about the agent processes, and supported operating systems.

How the Security Center agent works

The Security Center agent automatically sends connection information of the agent to the Security Center server in real time.

If the Security Center server has not received any information from the agent for 12 hours, it determines that the server where the agent runs is disconnected. The Security Center server then changes the security status of the server to Unprotected in the console.

Agent processes

Note Security Center uses the root account to run the Security Center agent processes on a Linux server. Security Center uses the system account to run the Security Center agent processes on a Windows server.
