Description
As automatic logins are a known security risk for other than "kiosk" types of systems, GNOME automatic login should be disabled in pam.conf.
ℹ️ Check
Determine if autologin is enabled for the GNOME desktop.
# egrep "auth|account" /etc/pam.d/gdm-autologin | grep -vc ^#
If the command returns other than "0", this is a finding.
✔️ Fix
The root role is required.
Modify the /etc/pam.d/gdm-autologin file.
# pfedit /etc/pam.d/gdm-autologin
Locate the lines:
auth required pam_unix_cred.so.1
auth sufficient pam_allow.so.1
account sufficient pam_allow.so.1
Change the lines to read:
#auth required pam_unix_cred.so.1
#auth sufficient pam_allow.so.1
#account sufficient pam_allow.so.1
