Abstract
Providing for employing a real time firewall to secure components of an automation control network from unauthorized communication to or from such components is disclosed herein. A monitoring component can inspect at least a portion of an instance of communication directed toward or originating from a component of the automation control network. Such inspection can, e.g., be a deep packet inspection based on information received from a communication request and/or response protocol. A filtering component can selectively admit or deny propagation of the instance of communication based on the inspection and a predetermined security criterion. In such a manner, the subject innovation can provide for limited access to network components from office network machines and for securing components of an automation control network from influence by unauthorized entities.
