Who does this work

8 NICE work roles and 8 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-257860r1044940_chk)

Verify that the "/boot" mount point has the "nodev" option with the following command: $ mount | grep '\s/boot\s' /dev/sda1 on /boot type xfs (rw,nodev,relatime,seclabel,attr2) If the "/boot" file system does not have the "nodev" option set, this is a finding.

Fix Text (F-61525r925566_fix)

Modify "/etc/fstab" to use the "nodev" option on the "/boot" directory.
