Check Text ( C-2060r3_chk )
This check applies to the global zone only. Determine the type of zone that you are currently securing. # zonename If the command output is "global", this check applies. Check the permission of the menu.lst file. On systems that have a ZFS root, the menu.lst file is typically located at /pool-name/boot/grub/menu.lst where "pool-name" is the mount point for the top-level dataset. On systems that have a UFS root, the menu.lst file is typically located at /boot/grub/menu.lst . Procedure: # ls -lL /pool-name/boot/grub/menu.lst or # ls -lL /boot/grub/menu.lst If menu.lst has a mode more permissive than 0600, this is a finding.

Check the permission of the menu.lst file.

On systems that have a ZFS root, the menu.lst file is typically located at /pool-name/boot/grub/menu.lst where "pool-name" is the mount point for the top-level dataset.

On systems that have a UFS root, the menu.lst file is typically located at /boot/grub/menu.lst .

Procedure:
# ls -lL /pool-name/boot/grub/menu.lst
or
# ls -lL /boot/grub/menu.lst

If menu.lst has a mode more permissive than 0600, this is a finding.
