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.

Home directories for application accounts requiring different group ownership must be documented using site-defined procedures.

Fix Text (F-16473r294283_fix)

Change the group owner for users home directories to the primary group of the assigned user: # chgrp <groupname> <directoryname> (Replace examples with appropriate group and home directory.) Document all changes.
