Who does this work

6 NICE work roles and 5 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-259552r1038915_chk)

Verify the macOS system is configured to disable accounts after 35 days of inactivity with the following command: /usr/bin/pwpolicy -getaccountpolicies 2> /dev/null | /usr/bin/tail +2 | /usr/bin/xmllint --xpath '//dict/key[text()="policyAttributeInactiveDays"]/following-sibling::integer[1]/text()' - If the result is not "35", this is a finding.

Fix Text (F-63199r1038914_fix)

Configure the macOS system to disable accounts after 35 days of inactivity with the following command. This setting may be enforced using local policy or by a directory service. To set local policy to disable an inactive user after 35 days, edit the current password policy to contain the following <dict> within the "policyCategoryAuthentication": [source,xml] ---- <dict> <key>policyContent</key> <string>policyAttributeLastAuthenticationTime &gt; policyAttributeCurrentTime - (policyAttributeInactiveDays * 24 * 60 * 60)</string> <key>policyIdentifier</key> <string>Inactive Account</string> <key>policyParameters</key> <dict> <key>policyAttributeInactiveDays</key> <integer>35</integer> </dict> </dict> ---- After saving the file and exiting to the command prompt, run the following command to load the new policy file, substituting the path to the file in place of "$pwpolicy_file". [source,bash] ---- /usr/bin/pwpolicy setaccountpolicies $pwpolicy_file ----
