Details
Setting the boot loader password will require that anyone rebooting system must enter a password before being able to set command line boot parameters
Rationale:
Requiring a boot password upon execution of the boot loader will prevent an unauthorized user from entering boot parameters or changing the boot partition. This prevents users from weakening security (e.g. turning off SELinux at boot time).
Solution
Run the following:
#!/bin/bash
grub-md5-crypt | tee /tmp/$$
x=$(tail -1 /tmp/$$)
/bin/rm -f /tmp/$$
ed /etc/grub.conf << END > /dev/null 2>&1
g/^password/d
$
?^#?
a
password –md5 $x
.
w
q
END
Default Value:
OS Default: No
