The Sun Fire System Controller controls the hardware components which comprise a Sun Fire 15K server. Because it is a central control point for the entire Sun Fire frame, it represents an excellent attack point for intruders. In order to improve reliability, availability, and serviceability (RAS), the SC must be secured against malicious misuse and attack.
The Sun Fire 15K SC runs the Solaris 8 OE and many of the recommendations made in other Sun BluePrints OnLine articles about hardening the Solaris OE apply to the Sun Fire SC. This article uses these recommendations, in addition to SC-specific suggestions, to improve the overall security posture of a Sun Fire 15K SC by dramatically reducing potential access points to the SC and installing secure access mechanisms. In addition, the implementation of these recommendations can be automatically installed by the Solaris Security Toolkit software.
