Understanding the Default Settings of Oracle ILOM

Oracle ILOM comes preconfigured with most services enabled by default. This makes the deployment of Oracle ILOM simple and straightforward. However, each open port on the server represents a potential attach point by a malicious user. It is therefore important to understand the initial Oracle ILOM settings, and their purpose, and to choose which services are actually required for a deployed system. For best security, enable only the required Oracle ILOM services.

The following table lists the services that are enabled by default with Oracle ILOM.
