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

AltaNivel 1Automatizadaedge

Descripción

This policy 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. Rationale: Allowing hostnames to be exempt from HSTS policy checks could allow for protocol downgrade attacks and cookie hijackings. The policy is Disabled when it is not present: the audit prints 'absent' when neither the value HSTSPolicyBypassList nor a populated list subkey HSTSPolicyBypassList exists under HKLM\SOFTWARE\Policies\Microsoft\Edge, otherwise the configured entries.
