Discussion

Failure to restrict system access to authenticated users negatively impacts SLEM 5 security.

Check Content

Note: If a graphical user interface is not installed, this requirement is not applicable.

Verify SLEM 5 does not allow unattended or automatic logon via the GUI.

Check that unattended or automatic login is disabled with the following commands:

     > grep -i ^DISPLAYMANAGER_AUTOLOGIN /etc/sysconfig/displaymanager
     DISPLAYMANAGER_AUTOLOGIN=""

     > grep -i ^DISPLAYMANAGER_PASSWORD_LESS_LOGIN /etc/sysconfig/displaymanager
     DISPLAYMANAGER_PASSWORD_LESS_LOGIN="no"

If the "DISPLAYMANAGER_AUTOLOGIN" parameter includes a username or the "DISPLAYMANAGER_PASSWORD_LESS_LOGIN" is not set to "no", this is a finding.

Fix Text

Note: If a graphical user interface is not installed, this requirement is not applicable.

Configure SLEM 5 GUI to not allow unattended or automatic logon to the system.

Add or modify the following lines in the "/etc/sysconfig/displaymanager" file:

DISPLAYMANAGER_AUTOLOGIN=""
DISPLAYMANAGER_PASSWORD_LESS_LOGIN="no"
