Who does this work

8 NICE work roles and 7 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-213431r1207394_chk)

Verify the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Microsoft Defender Antivirus >> Exclusions >> "Turn off Auto Exclusions" is set to "Disabled". Procedure: Use the Windows Registry Editor to navigate to the following key: HKLM\Software\Policies\Microsoft\Windows Defender\Exclusions Criteria: If the value "DisableAutoExclusions" is REG_DWORD = 0, this is not a finding. NOTE: The configuration of WNDF-AV-000100 will likely hide this setting from being reviewed. If compliance can be shown via group policy editor or other means, this is not a finding.

Fix Text (F-14654r823033_fix)

Set the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Microsoft Defender Antivirus >> Exclusions >> "Turn off Auto Exclusions" to "Disabled".
