Ensure 'Remote Encryption Protection Configured State' is set to 'Audit: Generate EDR detections without blocking' or higher

HighLevel 1Automatedintune-defender

Description

This policy setting sets the mode for Remote Encryption Protection in Microsoft Defender Antivirus, which can detect and block attempts to replace local files with encrypted versions from another device. The recommended state for this setting is: Audit: Generate EDR detections without blocking. Configuring this setting to Block: Prevent suspicious and malicious behaviors also conforms to the benchmark. Note: Configuring the value to either Default or Off does not conform to this benchmark. Audit: reads the registry value(s) behind this Defender policy (HKLM\SOFTWARE\Policies\Microsoft\Windows Defender) and prints compliant only when each satisfies the benchmark value. Policy delivered by Intune only appears here once it has been applied to the device.

How it is checked

Audit method: Windows registry

registry

$bad = @(); $v = (Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\PolicyManager' -Name 'RemoteEncryptionProtectionConfiguredState' -ErrorAction SilentlyContinue).'RemoteEncryptionProtectionConfiguredState'; if (-not ($null -ne $v -and @(2,1) -contains [int64]$v)) { $bad += 'RemoteEncryptionProtectionConfiguredState=' + $v }; if ($bad.Count -eq 0) { 'compliant' } else { 'non-compliant: ' + ($bad -join ', ') }

Expected output: compliant
