Ensure 'Macro Runtime Scan Scope' is set to 'Enabled: Enable for all documents'

Opis

This policy setting specifies the behavior for both the VBA and Excel 4.0 (XLM) runtime scan features. Multiple Office apps support VBA macros, but XLM macros are only supported by Excel. The VBA and XLM runtimes report to an antivirus system certain high-risk code behaviors the macro is about to execute. This allows the antivirus system to indicate whether or not the macro behavior is malicious. Rationale: Macros may contain harmful functions designed to inject malicious software into a system, escalate privilege, and be a first entry point in the attack chain. User setting: the audit checks HKEY_USERS\<SID>\SOFTWARE\Policies\Microsoft\office\16.0\common\security:macroruntimescanscope (REG_DWORD) in every loaded user hive (S-1-5-21-*) and is compliant when each holds 2. It prints 'no-user-hive-loaded' (FAIL) when no user profile is loaded, so scan while users are logged on.

Kako se proverava

Metod provere: Windows registar

registry

$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\' + $s + '\SOFTWARE\Policies\Microsoft\office\16.0\common\security') -Name 'macroruntimescanscope' -ErrorAction SilentlyContinue).'macroruntimescanscope'; if (-not ($null -ne $v -and @(2) -contains [int64]$v)) { $bad += $s + ':macroruntimescanscope=' + $v } }; if ($bad.Count -eq 0) { 'compliant' } else { 'non-compliant: ' + ($bad -join ', ') } }

Očekivani izlaz: compliant
