Abstract: A method of securing data traffic between a local and remote host systems is provided. The method includes autogenerating a filter having rules associated with a defined tunnel. The filter rules are used to permit or deny acceptance of transmitted data by the host system and to direct traffic to the tunnel. The tunnel, on the other hand, is used to keep data confidential. The method further includes autogeneration of a counterpart tunnel and associated filter to be used by the remote host when in communication with the local host. The method further autogenerates a new filter to reflect changes to any one of the tunnels and autodeactivates the filter associated with a deleted tunnel.
