The Smart Grid: An Introduction, prepared for the U.S. Department of Energy by Litos Strategic Communications under contract No. Since existing control system architectures are not random and therefore response characteristics are reproducible, the strength of potential adversaries is amplified. This system, illustrated in Figure 5 and described in the following section, allows companies to capitalize on rapid-fire strategic challenges and retain their stability [1]." The Solution: SAFe Offers a Dual Operating System. To protect control systems, well-established information security practices must also be utilized. This article provides a brief overview of smart-grid technology, and then explores the safety considerations that should be addressed in the design of smart grid technology equipment, particularly in low-voltage AC power applications operating below 1000 V AC. DDoS attacks utilize networks of infected computerswhose owners often do not even know that they have been infectedto overwhelm target networks with millions of fake requests for information over the Internet. The threat of a Trojan horse embedded in the control center software can only be addressed by means of careful security measures within the commercial firms that develop and supply this software along with careful security screening of the utility and outside service personnel who perform software maintenance within the centers. Likewise, other product applicable safety modules, such as requirements for outdoor equipment, can serve as supplements or overlays to the base meter standard in this case. In addition to the physical threats to such centers and the communication links that flow in and out of them, one must be concerned about two other factors: the reliability of the operators within the centers and the possibility that insecure code has been added to a program in a center computer. A successful terrorist attempt to disrupt the power delivery system could have adverse effects on national security, the economy, and the lives of every citizen. Despite the increase in the utilization of AMI, there has been very little assessment or R&D effort to identify the security needs for such systems. return true; } } [CDATA[ */ The Academy compiled a list of twenty accomplishments that have affected virtually everyone in the world. if ('undefined' !== typeof arguments[1].hitType) { Safety of smart Grid Data Security: . While the direct physical destruction of generators, substations, or power lines may be the most obvious strategy for causing blackouts, activities that compromise the operation of sensors, communications, and control systems by spoofing, jamming, or sending improper commands could also disrupt the system, cause blackouts, and in some cases result in physical damage to key system components. 14621. , and other security systems often overlook a piece of their system that can shut down the entire system if it isnt properly maintained: battery backup. }; Mr. Gies has become a leading subject matter expert for his company in the field of global product safety compliance, working primarily with Alcatel-Lucents wireless base station equipment. Part of the problem is that the existing control systems, which were originally designed for use with proprietary, stand-alone communication networks, were later connected to the Internet (because of its productivity advantages and lower costs) but without adding the technology needed to make them secure.
