Remove Autologin Capabilities from the GNOME desktop
Description
The GNOME Display Manager is used for login session management. See the manual page gdm(1) for more information. By default, GNOME automatic login is defined in /etc/pam.d/gdm-autologin to allow users to access the system without a password. As automatic logins are a known security risk for other than "kiosk" types of systems, GNOME automatic login should be disabled in /etc/pam.d/gdm-autologin. Audit: automated read-only check derived from the CIS audit procedure; it prints "compliant" when the control is met.
How it is checked
Audit method: Shell command
f=/etc/pam.d/gdm-autologin; [ -f "$f" ] || { echo 0; exit 0; }; n=$(egrep "auth|account" "$f" | grep -vc "^#"); echo "$n"- Expected output
0
How it is fixed
Fix method: Guidance or infrastructure patch
Comment out or remove all lines from /etc/pam.d/gdm-autologin: # cp /etc/pam.d/gdm-autologin /etc/pam.d/gdm-autologin.orig # awk '{ if ( $1 ~ /auth/ || $1 ~ /account/) $1 = "#"$1 } { print };' /etc/pam.d/gdm-autologin > /etc/pam.d/gdm-autologin.CIS # cp /etc/pam.d/gdm-autologin.CIS /etc/pam.d/gdm-autologin
