The first step in configuring a secure Web services host is to install a minimum operating system configuration. While the installation and configuration is taking place, the system is not connected to any network. This prevents a malicious intruder from gaining access and corrupting the software base before it is secure.
Install a Minimal Operating System
To reduce the complexity and points of entry into the Web services host, do not install a graphical user interface. Instead, select the Core cluster and use the Customize to add SPARCompilers Bundled libC Cfront version (SUNWlibCf). Expand System and Network Administration and add System & Network Administration Framework (SUNWadmfw) and System administration core libraries (SUNWadmc). Finally, add terminal emulation support with Terminal Information (SUNWter).
Install the Recommended Patch Cluster
The latest consolidated patch file can be found at the Sunsolve web site (http://sunsolve.sun.com/). Note that the recommended minimal operating system configuration does not include all components covered by the recommended patch cluster. Patches in the cluster that affect components not installed will fail to install and will display an error code of 8. Do showrev –p to see what patches have been installed. Print a copy of this information and save it for future reference.
