Ensure 'Blocks external extensions from being installed' is set to 'Enabled'

高等級 1自動化chrome

說明

Enabling this setting blocks external extensions (an extension that is not installed from the Chrome Web Store) from being installed. The recommended state for this setting is: Enabled (1) Rationale: Allowing users to install extensions from other locations (not the Chrome Web Store) can lead to malicious extensions being installed. 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:BlockExternalExtensions (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.
