Control FWBlock

The interface between a Host and a Logical Subnet. Represents a possible point of control and a target for attack. If the Logical Subnet is an IP network, the Interface also represents the existence of an IP address.

A base class representing a route through a Host between any two distinct Logical Subnets of any kind.

Apply a default firewall rule at gateway host Gateway to drop messages sent via the gateway from FromSubnet to ToSubnet, unless they are service requests or responses.

Apply a default firewall rule at host Host to drop messages sent to the host from subnet LogicalSubnet, unless they are service requests or responses.

Apply a default firewall rule at host Host to drop messages sent to services running on the host from subnet LogicalSubnet. This strategy may represent a run-time adaptation in response to a threat, or a permanent restriction introduced by design or in accordance with an operational policy or user preference. It also triggers threats representing side effects that would be caused by such a restriction, which affect access to services running on Host but not other uses of its connection to LogicalSubnet.
