Ensure 'Disable Certificate Transparency enforcement for a list of Legacy Certificate Authorities' is set to 'Disabled'

高レベル 1自動chrome

説明

Google Chrome can disable the enforcing of Certificate Transparency requirements for a list of Legacy Certificate Authorities. If this setting is disabled, certificates not properly publicly disclosed as required by Certificate Transparency are untrusted. The recommended state for this setting is: Disabled (0) Rationale: Legacy Certificate Authorities shall follow the Certificate Transparency policy. The policy is Disabled when it is not present: the audit prints 'absent' when the list key HKLM\SOFTWARE\Policies\Google\Chrome\CertificateTransparencyEnforcementDisabledForLegacyCas is missing or empty, otherwise the configured entries.
