Title: Backplane filtering and firewalls

Abstract

Described herein are various technologies for providing active mitigation of cyber-attacks against industrial and other control systems. A filtering device is connected to a backplane of a control system and receives communications from various modules of the control system. The filter device analyzes the received communications and determines whether they are genuine and permissible communications for the control system. Validated signals are output to a communications bus of the control system by the filter device, while impermissible communications are blocked. The filter device can be interposed between the modules of the control system and the backplane, or the filter device can be included as a component of a control system backplane.
