On the other hand, most of the users are connected through an administrative network which is less sensitive and thus less secure than the operational network. The demand for connecting the networks is required for business continuity reasons and for day by day necessity. The presentation will analyze the threats with regard to networks connectivity and expand the model to other IP based networks. Some solutions will be analyzed and a novel solution will be presented to overcome the network connectivity problem.

Critical National Infrastructure is under a constant, yet invisible, threat from cyber hacking and cyber terror attempts that are being launched from external networks. These attacks (mainly – from the Internet) are targeting industrial Process Control Networks (PCN), Supervisory Control and Data Acquisition (SCADA) Networks and lower level Distributed Control Systems (DCS) and Process Control Systems (PCS) networks.

In the Electricity Utilities’ domain, these critical networks control and operate the very machinery which powers modern day civilization. Throughout North America, electricity utilities are challenged with the task of complying with the reliability standards mandated by NERC (North American Electric Reliability Corporation).

The NERC-CIP (Critical Infrastructure Protection) standards, recently revised in May 2009, provide a cyber security framework for the identification and protection of Critical Cyber Assets to support reliable operation of the Bulk Electric System. The following whitepaper introduces the reader to the Waterfall One-Way™ unidirectional cyber security solution, and explains its ideal fit for achieving both powerful cyber-security as well as NERC-CIP compliance.
