function Test-MtMdeQuickScanTime { <# .SYNOPSIS Checks that quick scan time configuration is not required .DESCRIPTION Verifies that the quick scan time setting does not need to be configured in Microsoft Defender Antivirus policies. Quick scans are replaced by real-time protection, so this setting is not required for compliance. .PARAMETER ComplianceLogic Determines how policy compliance is evaluated. 'AllPolicies' requires every assigned policy to be compliant; 'AnyPolicy' requires at least one. Default: 'AllPolicies'. .PARAMETER PolicyFiltering Determines which Defender Antivirus policies are evaluated. 'OnlyAssigned' (default) checks only assigned policies; 'IncludeUnassigned' includes unassigned policies; 'All' includes every policy. .PARAMETER ComplianceLogic Specify compliance logic: AllPolicies or AnyPolicy .PARAMETER PolicyFiltering Specify policy filtering: All, IncludeUnassigned, or OnlyAssigned .EXAMPLE Test-MtMdeQuickScanTime Returns $true as this setting is not required. .LINK https://maester.dev/docs/commands/Test-MtMdeQuickScanTime #> [CmdletBinding()] [OutputType([bool])] param( [ValidateSet('AllPolicies', 'AnyPolicy')] [string]$ComplianceLogic = 'AllPolicies', [ValidateSet('All', 'IncludeUnassigned', 'OnlyAssigned')] [string]$PolicyFiltering = 'OnlyAssigned' ) Write-Verbose "Running Test-MtMdeQuickScanTime..." if (!(Test-MtConnection Graph)) { Add-MtTestResultDetail -SkippedBecause NotConnectedGraph return $null } $deviceCount = 0 $policyConfig = $null try { $deviceCount = Get-MdeDeviceCount $policyConfig = Get-MdePolicyConfiguration -PolicyFiltering $PolicyFiltering } catch { Add-MtTestResultDetail -SkippedBecause Error -SkippedError $_ return $null } if ($deviceCount -eq 0) { Add-MtTestResultDetail -SkippedBecause Custom -SkippedCustomReason "No MDE-managed Windows devices found" return $null } if ($policyConfig.TotalCount -eq 0) { Add-MtTestResultDetail -SkippedBecause Custom -SkippedCustomReason "No assigned Microsoft Defender Antivirus policies found" return $null } try { $compliance = Test-MdePolicyCompliance -PolicyConfiguration $policyConfig ` -ComplianceLogic $ComplianceLogic ` -SettingId "device_vendor_msft_policy_config_defender_schedulequickscantime" ` -ComplianceCheck "NotRequired" $testResult = $compliance.IsCompliant if ($testResult) { $testResultMarkdown = "Well done.
