Best Practices Submission: The eeprom password should be set on all Solaris systems. On a system that does not an eeprom password set, a cracker can gain access to the root account and set the eeprom password himself. If he sets the eeprom to full inter-active mode and reboots the system, the unit will not boot without the eeprom password. If this happens, the eeprom chip must be physically replaced. Estimates I have seen place replace times at 2 to 4 weeks. That's 2 to 4 weeks you Solaris machine will be down, if you do not set an eeprom password.
