31.2. Disabling Console Program Access
To disable access by users to console programs, run the following command as root:
rm -f /etc/security/console.apps/*
In environments where the console is otherwise secured (BIOS and boot loader passwords are set, Ctrl+Alt+Delete is disabled, the power and reset switches are disabled, and so forth), you may not want to allow any user at the console to run
poweroff
, halt
, and reboot
, which are accessible from the console by default.
To disable these abilities, run the following commands as root:
rm -f /etc/security/console.apps/poweroff
rm -f /etc/security/console.apps/halt
rm -f /etc/security/console.apps/reboot
