“…The IEEE RTS-96 model specification was used in an NSTB workshop [11] to perform reliability analysis (Section 6.1.1) using the steady-state, load-shedding model (Section 6.1.2). The advantage of using the IEEE RTS-96 as a model of an electric grid is that it provides a standardized specification that can be reproduced in relatively inexpensive simulations.…”

“…The simple model uses 2 buses, while another model (still under development) uses 20 buses. Preliminary analysis of the FSM models suggests that the models are valid and that the simple model demonstrates the correct dynamics ( [11]). Because the FSM model is in its infancy, it is uncertain whether it can scale up to be able to simulate real electric grids.…”

“…Sandia has developed a methodology for performing reliability analysis on electric power systems that accounts for failures in electric power control systems caused by cyber attacks (see [11]). The failure of the control systems due to attacks is acknowledged with the assumption that cyber attacks will occur randomly throughout time and with equal probability.…”

“…After a sufficiently long simulation, summary measures of the metrics can be recorded. For example, "Impact Analysis from Cyber Intrusion for Electric Power Systems" [11] calculates the mean number of megawatt-hours (MWh) of load that are unserved every year due to the cyber attacks by simulating the system for a large number of years, summing the total MWh or unserved load, and dividing by the number of years.…”

“…While the probabilistic analysis methodology used in "Impact Analysis from Cyber Intrusion for Electric Power Systems" [11] does not currently assess the consequences of cyber attacks to other infrastructures and the economy, this extension is straightforward if a real electric grid with historic loads is used to model the system-wide impact of cyber attacks and dependencies on the components of the grid are known. For example, if it is known that a manufacturing facility was connected to a certain bus, the average amount of time each year that the facility is without power could be calculated by monitoring the status of the bus.…”

The goal of the work discussed in this document is to understand the risk to the nation of cyber attacks on critical infrastructures. The large body of research results on cyber attacks against physical infrastructure vulnerabilities has not resulted in clear understanding of the cascading effects a cyber-caused disruption can have on critical national infrastructures and the ability of these affected infrastructures to deliver services. This document discusses current research and methodologies aimed at assessing the translation of a cyber-based effect into a physical disruption of infrastructure and thence into quantification of the economic consequences of the resultant disruption and damage. The document discusses the deficiencies of the existing methods in correlating cyber attacks with physical consequences. The document then outlines a research plan to correct those deficiencies. When completed, the research plan will result in a fully supported methodology to quantify the economic consequences of events that begin with cyber effects, cascade into other physical infrastructure impacts, and result in degradation of the critical infrastructure's ability to deliver services and products.This methodology enables quantification of the risks to national critical infrastructure of cyber threats. The work addresses the electric power sector as an example of how the methodology can be applied. Cyber and Physical Infrastructure Interdependencies 4This page intentionally left blank.
