Insanely Securing Your Unix or Linux Systems

The Linux and Unix Menagerie: "2. Take the idea of making generic accounts su-only one step further and start restricting access to the su binary as much as possible. If you can get away with it, ensure that your /usr/bin/su file is chowned to root:special and chmod'ed to 4750. Now only root and users who belong to the "special" group can even use su to do anything. Everyone else will get an error just for trying to run it."
