Abstract
The invention provides an improved network and methods of operation thereof for use in or with process control systems, computer-based manufacturing or production control systems, environmental control systems, industrial control system, and the like (collectively, “control systems”). Those networks utilize a unique combination of firewalls, intrusion detection systems, intrusion protection devices and/or other devices for hardening (e.g., security against hacking, intrusion or other mischievous conduct) and/or intrusion detection. The networks and methods have application, by way of example, in plants, sites and other facilities in which networks that support control systems interface with corporate, business or other networks.
