Ensure 'Macro Notification Settings' is set to 'Enabled: Disable VBA macros except digitally signed macros'

VisokaNivo 1Automatskaoffice

Opis

This policy setting controls how the specified applications warn users when Visual Basic for Applications (VBA) macros or Excel 4.0 (XLM) macros are present. Multiple Office apps support VBA macros, but XLM macros are only supported by Excel. Disable VBA macros except digitally signed macros: The application displays the Trust Bar for digitally signed macros, allowing users to enable them or leave them disabled. Rationale: When users open files in Excel that contain VBA macros, Excel opens the files with the macros disabled, and displays the Trust Bar with a warning that macros are present and have been disabled. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\excel\security:vbawarnings (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 3. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.

Kako se proverava

$sids = @(Get-ChildItem -Path 'Registry::HKEY_USERS' -ErrorAction SilentlyContinue | Where-Object { $_.PSChildName -match '^S-1-5-21-\d+-\d+-\d+-\d+$' } | ForEach-Object { $_.PSChildName }); if ($sids.Count -eq 0) { 'no-user-hive-loaded' } else { $bad = @(); foreach ($s in $sids) { $v = (Get-ItemProperty -Path ('Registry::HKEY_USERS\' + $s + '\SOFTWARE\Policies\Microsoft\office\16.0\excel\security') -Name 'vbawarnings' -ErrorAction SilentlyContinue).'vbawarnings'; if (-not ($null -ne $v -and @(3) -contains [int64]$v)) { $bad += $s + ':vbawarnings=' + $v } }; if ($bad.Count -eq 0) { 'compliant' } else { 'non-compliant: ' + ($bad -join ', ') } }

Očekivani izlaz: compliant
