“Welcome back to an exciting odyssey in making your Linux box
more secure. In the previous article we dealt with various issues
like BIOS security passwords, securing your LILO prompt with a
password, restricting the use of “setuid” and “setgid” programs

machine is one unplugged from the electrical point.” Another point
we would like to stress upon is “Security is not a solution but a
way of life.”
