Description
This policy setting allows the disabling of scheduled and real-time scanning for any file opened by any of the specified processes. The process itself will not be excluded. To exclude the process, use the Path exclusion. Processes should be added under the options for this setting. Each entry must be listed as a name value pair where the name should be a string representation of the path to the process image. Note that only executables can be excluded. For example, a process might be defined as: "c:\windows\app.exe". The value is not used and it is recommended that this be set to 0.

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-213430r1207392_chk)

Verify the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> Microsoft Defender Antivirus >> Exclusions >> "Process Exclusions" is set to "Disabled" or "Not Configured". Procedure: Use the Windows Registry Editor to navigate to the following key: HKLM\Software\Policies\Microsoft\Windows Defender\Exclusions Criteria: If the value "Exclusions_Processes" does not exist, 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-14653r1190709_fix)
