My external security gateways are accepting tcp/443 inbound traffic via an implied rule from the public internet. I have examined the implied rules in SmartConsole by selecting the appropriate policy Actions => Implied Rules. I can't seem to identify which implied rule it is that is allowing https. None of the implied rules how "https" as the service and when I go to the left and click on "Configuration" it doesn't seem that any of the options I have selected would apply .
There is one option checked (see screen shot below) that states "Accept Web and SSH connections for Gateways administration (Small Office Appliance)" that I would assume allows https but these gateways are 15,400 appliances. Would this rule still apply?
I am in need of disabling https to these external security gateways as this came up as a finding from auditors on a external pen scan.
Also, I do not have SSL Extender enabled.
