TMA-DEFENDER-1.17

Ensure 'Control whether exclusions are visible to local users' is set to 'Enabled'

보통레벨 1자동defender

설명

This policy setting controls whether Microsoft Defender Antivirus exclusions are visible to local users on the system. The recommended state for this setting is: Enabled. Warning: This setting requires at least Microsoft Defender for Endpoint Plan 1 (Foundational enterprise endpoint protection) to function. If Plan 1 is not in use, an exception to this recommendation is required. Rationale: Only administrators should be able to view and manage Microsoft Defender Antivirus exclusions. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Microsoft\Windows Defender:HideExclusionsFromLocalUsers (REG_DWORD); compliant when it is 1. Remediation writes 1 locally; in a domain set it through the ADMX so Group Policy does not revert it.
