Ensure 'Require online OCSP/CRL checks for local trust anchors' is set to 'Enabled'

MittelStufe 2Automatisiertchrome

Beschreibung

Google Chrome performs revocation checking for server certificates that successfully validate and are signed by locally-installed CA certificates. If Google Chrome is unable to obtain revocation status information, such certificates will be treated as revoked ('hard-fail'). Disabled: Google Chrome uses existing online revocation-checking settings. The recommended state for this setting is: Enabled (1) Rationale: Certificates shall always be validated. 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:RequireOnlineRevocationChecksForLocalAnchors (REG_DWORD); compliant when it is 1. Remediation writes 1 locally; in a domain set it through the ADMX so Group Policy does not revert it.

So wird geprüft

registry

$v = (Get-ItemProperty -Path 'Registry::HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome' -Name 'RequireOnlineRevocationChecksForLocalAnchors' -ErrorAction SilentlyContinue).'RequireOnlineRevocationChecksForLocalAnchors'; if ($null -eq $v) { 'unset' } elseif (($null -ne $v -and @(1) -contains [int64]$v)) { 'compliant' } else { "non-compliant: $v" }

Erwartete Ausgabe: compliant

So wird behoben

Behebungsmethode: Shell-Befehl
