The ability to boot from removable media is the same as being able to boot into single user or maintenance mode without a password. This ability could allow a malicious user to boot the system and perform changes possibly compromising or damaging the system. It could also allow the system to be used for malicious purposes by a malicious anonymous user.
Determine if the system is configured to boot from devices other than the system startup media by running command:
# bootlist -m normal -o
The returned values should be "hdisk{x}".
If the system is setup to boot from a non-hard disk device, this is a finding.
Additionally, ask the SA if the machine is setup for "multi-boot" in the SMS application. If multi-boot is enabled, the firmware will stop at boot time and request which image to boot from the user.
If "multi-boot" is enabled, this is a finding.Configure the system to only boot from system startup media: # bootlist -m normal hdisk<x> Set "multi-boot" to "off" in the SMS application.
