Ensure 'Allow proceeding from the SSL warning page' is set to 'Disabled'

MediaNivel 2Automatizadachrome

Descripción

This setting controls whether a user is able to proceed to a webpage when an invalid SSL certificate warning has occurred. The recommended state for this setting is: Disabled (0) Rationale: Sites protected by SSL should always be recognized as valid in the web browser. Allowing a user to make the decision as to whether there appears to be an invalid certificate could open an organization up to users visiting a site that is otherwise not secure and/or malicious in nature. 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:SSLErrorOverrideAllowed (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.
