ActiveX controls and plug-ins must be disallowed (Restricted Sites zone).

Description

Discussion Text

This policy setting allows you to manage whether ActiveX controls and plug-ins can be run on pages from the specified zone. ActiveX controls not marked as safe should not be executed. If you enable this policy setting, controls and plug-ins can run without user intervention. If you disable this policy setting, controls and plug-ins are prevented from running.

Assessment Script Powered by AISyntax-verified

A standalone PowerShell script to assess this control automatically. Review before running it in your environment.

Syntax-checked as valid PowerShell. Not executed here — running it for real needs the actual ms_ie10 target this check assesses.

# OVAL Definition: oval:mil.disa.fso.ie:def:285
$regPath = "HKLM:\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\4\1200"
$regValue = (Get-ItemProperty -Path $regPath -ErrorAction SilentlyContinue).Value
if ($regValue -eq 3) { Write-Output "PASS"; Exit 0 } else { Write-Output "FAIL"; Exit 1 }

Remediation

Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Restricted Sites Zone -> "Run ActiveX controls and plugins" to "Enabled", and select "Disable" from the drop-down box.
