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-215419r991589_chk)

Check for the existence of the "/etc/hosts.allow" and "/etc/hosts.deny" files using commands: # ls -la /etc/hosts.allow -rw-r--r-- 1 root system 11 Jan 28 11:09 /etc/hosts.allow # ls -la /etc/hosts.deny -rw-r--r-- 1 root system 0 Jan 28 11:02 /etc/hosts.deny If either file does not exist, this is a finding. Check for the presence of a default deny entry using command: # grep -E "ALL:[[:blank:]]*ALL" /etc/hosts.deny ALL:ALL If the "ALL: ALL" entry is not present in the "/etc/hosts.deny" file, any TCP service from a host or network not matching other rules will be allowed access. If the entry is not in "/etc/hosts.deny", this is a finding.

Fix Text (F-16615r294709_fix)

Edit the "/etc/hosts.allow" and "/etc/hosts.deny" files to configure access restrictions. Add "ALL: ALL" entry to "/etc/hosts.deny" file.
