A SunFire 15K domain must be secured against unauthorized access to protect it and the information it contains. A secure system also improves RAS as the system will be more secure from malicious misuse and attack.
SunFire 15K domains run the Solaris 8 OE. Many of the recommendations made in other Sun BluePrints OnLine articles about hardening Solaris OE apply to SunFire 15K domains. This article uses these recommendations, in addition to domain-specific suggestions, to improve the overall security posture of a SunFire 15K domain by dramatically reducing potential access points to the domain and by installing secure access mechanisms. In addition, a mechanism is provided to automate the installation of these recommendations through the Solaris Security Toolkit software.
