The system must not allow autologin capabilities from the GNOME desktop.

As automatic logins are a known security risk for other than "kiosk" types of systems, GNOME automatic login should be disabled in pam.conf.

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.

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
