CCE-90877-2

Platform: rhel7Date: (C)2017-06-29   (M)2018-10-29



Disable Ctrl-Alt-Del Reboot Activation By default, the system includes the following line in '/etc/init/control-alt-delete.conf' 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"'


Parameter:


Technical Mechanism: 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. Fix: # The process to disable ctrl+alt+del has changed in RHEL7. # Reference: https://access.redhat.com/solutions/1123873 ln -sf /dev/null /etc/systemd/system/ctrl-alt-del.target
