TMA-CHROME-4.1.1

Ensure 'Allow or deny screen capture' is set to 'Disabled'

MittelStufe 2Automatisiertchrome

Beschreibung

This setting controls whether Google Chrome can use screen-share APIs including web-based online meetings, video, or screen sharing. Rationale: Allowing screen-share APIs within Google Chrome could potentially allow for sensitive data to be shared via screen captures. Audit reads the Group Policy registry value and prints 'compliant', 'unset' (policy not configured, reported as FAIL) or the non-compliant value. Registry value: HKLM\SOFTWARE\Policies\Google\Chrome:ScreenCaptureAllowed (REG_DWORD); compliant when it is 0. Remediation writes 0 locally; in a domain set it through the ADMX so Group Policy does not revert it.

So wird geprüft

registry

$v = (Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome' -Name 'ScreenCaptureAllowed' -ErrorAction SilentlyContinue).'ScreenCaptureAllowed'; if ($null -eq $v) { 'unset' } elseif (($null -ne $v -and @(0) -contains [int64]$v)) { 'compliant' } else { "non-compliant: $v" }

Erwartete Ausgabe: compliant

So wird behoben
