You can use a LocalSystem account or specify a different account for the NetIQ Security Agent for Windows service (Windows agent service). During installation, when you provide the name or IP address of the Secure Configuration Manager Core Services computer, the installation process automatically registers the installed agent with Core Services. You can also specify the ports used by the agent to communicate with Secure Configuration Manager. For more information about the agent service account, see Changing the Agent Service Account Settings. For more information about ports, see Understanding Port Requirements.
