Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-235031r991591_chk)

Note: If a graphical user interface is not installed, this requirement is Not Applicable. Verify the SUSE operating system 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" If parameter is not set to "no", this is a finding.

Fix Text (F-38182r619363_fix)

Note: If a graphical user interface is not installed, this requirement is Not Applicable. Configure the SUSE operating system GUI to not allow unattended or automatic logon to the system. Add or edit the following lines in the "/etc/sysconfig/displaymanager" configuration file: DISPLAYMANAGER_AUTOLOGIN="" DISPLAYMANAGER_PASSWORD_LESS_LOGIN="no"
