Disable Ctrl-Alt-Del Reboot Activation
By default, the system includes the following line in
to reboot the system when the Ctrl-Alt-Del key sequence is pressed:
'exec /sbin/shutdown -r now "Control-Alt-Delete pressed"'
To configure the system to log a message instead of
rebooting the system, alter that line to read as follows:
'exec /usr/bin/logger -p security.info "Control-Alt-Delete pressed"'
A locally logged-in user who presses Ctrl-Alt-Del, when at the console,
can reboot the system. If accidentally pressed, as could happen in
the case of mixed OS environment, this can create the risk of short-term
loss of availability of systems due to unintentional reboot.
In the GNOME graphical environment, risk of unintentional reboot from the
Ctrl-Alt-Del sequence is reduced because the user will be
prompted before any action is taken.
# The process to disable ctrl+alt+del has changed in RHEL7.
