put the line
restricted
in your /etc/lilo.conf file in the section where your parameters etc
related
to Linux are written. And run
/sbin/lilo -v
And reboot.
This will stop anyone from passing arguments to kernet using Lilo
prompt. Like "single" "vga=ZXY" etc etc [Thanks Binand]

Make a file called /etc/shutdown.allow and enter the names of users
you wish to be able to shutdown the system. Warn you, this is never a
good idea
to have this file. Let anyone be able to shutdown the system. But let
the bootup be 100% secure.. at times, suppose power is going to be
turned off at a short notice then it is better that the present person
can perform a shutdown. Think about it. I removed this file after some
bitter experiences and three re-installs of the filesystems.
