Description
Leaving the user list enabled is a security risk because it allows anyone with physical access to the system to enumerate known user accounts without authenticated access to the system.

Who does this work

5 NICE work roles and 5 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-281287r1166813_chk)

Note: This requirement assumes the use of the RHEL 10 default graphical user interface, the GNOME desktop environment. If the system does not have any graphical user interface installed, this requirement is not applicable. Verify RHEL 10 disables the user login list for graphical user interfaces with the following command: $ gsettings get org.gnome.login-screen disable-user-list true If the setting is "false", this is a finding.

Fix Text (F-85753r1166812_fix)

Configure RHEL 10 to disable the user list at login for graphical user interfaces. Note: The example below is using the database "local" for the system. If the system is using another database in "/etc/dconf/profile/user", the file should be created under the appropriate subdirectory. Create a database to contain the systemwide screensaver settings (if it does not already exist) with the following command: $ sudo vi /etc/dconf/db/local.d/02-login-screen [org/gnome/login-screen] disable-user-list=true Update the system databases: $ sudo dconf update
