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-258896r991589_chk)

At the command line, run the following command: # stat -c "%n permissions are %a and owned by %U:%G" /etc/ssh/*key Example result: /etc/ssh/ssh_host_dsa_key permissions are 600 and owned by root:root /etc/ssh/ssh_host_ecdsa_key permissions are 600 and owned by root:root /etc/ssh/ssh_host_ed25519_key permissions are 600 and owned by root:root /etc/ssh/ssh_host_rsa_key permissions are 600 and owned by root:root If any key file listed is not owned by root or not group owned by root or does not have permissions of "0600", this is a finding.

Fix Text (F-62545r933748_fix)

At the command line, run the following commands for each returned file: # chmod 600 <file> # chown root:root <file> # systemctl restart sshd.service
