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-215232r991589_chk)

Check system default for "maxrepeats" attribute: # lssec -f /etc/security/user -s default -a maxrepeats default maxrepeats=3 If the default "maxrepeats" is greater than "3", or its value is not set, or its value is set to "0", this is a finding. Check the "maxrepeats" setting for all users using: # lsuser -a maxrepeats ALL The above command should yield the following output: root maxrepeats=3 daemon maxrepeats=3 bin maxrepeats=3 sys maxrepeats=3 If the "maxrepeats" setting for any user is greater than "3", or its value is set to "0", this is a finding.

Fix Text (F-16428r294148_fix)

Use the "chsec" command to set "maxrepeats" to "3" for the default stanza: # chsec -f /etc/security/user -s default -a maxrepeats=3 Use the "chsec" command to set "maxrepeats" to "3" for all the users who have "maxrepeats" values that are greater than "3", or its value is set to "0": # chuser maxrepeats=3 [user_name]
