Title

The system must not allow autologin capabilities from the GNOME desktop. (Cat I impact)

Discussion

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

Check Content

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 Text

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
