Ensure 'List of names that will bypass the HSTS policy check' is set to 'Disabled'

AltaNível 1Automatizadachrome

Descrição

This setting allows a list of names to be specified that will be exempt from HTTP Strict Transport Security (HSTS) policy checks, then potentially upgraded from http:// to https://. The recommended state for this setting is: Disabled (0) Rationale: Allowing hostnames to be exempt from HSTS checks could allow for protocol downgrade attacks and cookie hijackings. The policy is Disabled when it is not present: the audit prints 'absent' when the list key HKLM\SOFTWARE\Policies\Google\Chrome\HSTSPolicyBypassList is missing or empty, otherwise the configured entries.
