An ad hoc network formed of electronic communication control devices for scanning each packet that crosses an interface and allowing a packet through the network interface only if the packet meets policy criteria, otherwise rejecting the packet. The electronic communication control devices have a unique communication method that exists between electronic communication control device chipsets. This method is transparent to other devices on the network so that only an electronic communication control device can communicate with another electronic communication control device. This gives a network interface adapter equipped with an electronic communication control device the ability to form an ad hoc network and communicate with other interface adapters and port line cards throughout the ad hoc network. This ad hoc network allows electronic communication control device equipped network interface units to promulgate a communication policy between units. Rejection may be of several forms including deliberate TCP/IP rules manipulation. The ad hoc network may identify and repel denial of service attacks and impede virus propagation.
