TMA-CHROME-1.26
Ensure 'Origins or hostname patterns for which restrictions on insecure origins should not apply' is set to 'Disabled'
Description
Google Chrome can use a list of origins (URLs) or hostname patterns (such as "*.example.com") for which security restrictions on insecure origins will not apply and are prevented from being labeled as "Not Secure" in the omnibox. The recommended state for this setting is: Disabled (0) Rationale: Insecure contexts shall always be labeled as insecure. The policy is Disabled when it is not present: the audit prints 'absent' when the list key HKLM\SOFTWARE\Policies\Google\Chrome\OverrideSecurityRestrictionsOnInsecureOrigin is missing or empty, otherwise the configured entries.
How it is checked

$l = @((Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\OverrideSecurityRestrictionsOnInsecureOrigin' -ErrorAction SilentlyContinue).PSObject.Properties | Where-Object { $_.Name -notlike 'PS*' } | ForEach-Object { "$($_.Value)" }); if ($l.Count -eq 0) { 'absent' } else { 'configured: ' + ($l -join ', ') }- Expected output
absent
How it is fixed
Fix method: Guidance or infrastructure patch
Configure through Group Policy: Computer Configuration\Policies\Administrative Templates\Google\Google Chrome\Origins or hostname patterns for which restrictions on insecure origins should not apply = Disabled.
